suggestopedia

Suggestopedia (USA English) or Suggestopaedia (UK English) is a teaching method developed by the Bulgarian psychotherapist Georgi Lozanov. It is used in different fields, but mostly in the field of foreign language learning. Lozanov has claimed that by using this method a teacher's students can learn a language approximately three to five times as quickly as through conventional teaching methods.

Suggestopedia has been called a "pseudo-science". It strongly depends on the trust that students develop towards the method by simply believing that it works.

The theory applied positive suggestion in teaching when it was developed in the 1970s. However, as the method improved, it has focused more on “desuggestive learning” and now is often called “desuggestopedia.”  Suggestopedia is a portmanteau of the words “suggestion” and “pedagogy". A common misconception is to link "suggestion" to "hypnosis". However, Lozanov intended it in the sense of offering or proposing, emphasising student choice.

purpose and theory

The intended purpose of Suggestopedia was to enhance learning by tapping into the power of suggestion. Lozanov claims in his website, Suggestology and Suggestopedy, that “suggestopedia is a system for liberation”; liberation from the “preliminary negative concept regarding the difficulties in the process of learning” that is established throughout their life in the society. Desuggestopedia focuses more on liberation as Lozanov describes “desuggestive learning” as “free, without a mildest pressure, liberation of previously suggested programs to restrict intelligence and spontaneous acquisition of knowledge, skills and habits.” The method implements this by working not only on the conscious level of human mind but also on the subconscious level, the mind’s reserves. Since it works on the reserves in human mind and brain, which are said to have unlimited capacities, one can teach more than other methods can teach in the same amount of time.

in practice

Physical surroundings and atmosphere in classroom are the vital factors to make sure that "the students feel comfortable and confident", and various techniques, including art and music, are used by the trained teachers. The lesson of Suggestopedia consisted of three phases at first: deciphering, concert session (memorization séance), and elaboration.

Deciphering: The teacher introduces the grammar and lexis of the content.

Concert session (active and passive): In the active session, the teacher reads the text at a normal speed, sometimes intoning some words, and the students follow. In the passive session, the students relax and listen to the teacher reading the text calmly. Music (“Pre-Classical”) is played in the background.

Elaboration: The students finish off what they have learned with dramas, songs, and games.

Then it has developed into four phases as lots of experiments were done: introduction, concert session, elaboration, and production.

Introduction: The teacher teaches the material in “a playful manner” instead of analyzing lexis and grammar of the text in a directive manner.

Concert session (active and passive): In the active session, the teacher reads with intoning as selected music is played. Occasionally, the students read the text together with the teacher, and listen only to the music as the teacher pauses in particular moments. The passive session is done more calmly.

Elaboration: The students sing classical songs and play games while “the teacher acts more like a consultant”.

Production: The students spontaneously speak and interact in the target language without interruption or correction.

teachers

Teachers should not act directive, although this method is teacher-controlled but not student-controlled. For example, they should act as a real partner to the students, participating in the activities such as games and songs “naturally” and “genuinely.”  In the concert session, they should fully include classical art into their behaviors. Although there are many techniques that the teachers use, the factors such as “communication in the spirit of love, respect for man as a human being, the specific humanitarian way of applying there ‘techniques’” etc. are crucial. The teachers need not only to know the techniques and theoretical information but also to understand the theory and to acquire the practical methodology completely because if they implement those techniques without complete understanding, they will not be able lead their learners to successful results, or they could even cause a negative impact on their learning. Therefore, the teacher has to be trained in a course taught by the certified trainers.

Here are the most important factors for teachers to acquire, described by Lozanov.

    Covering a huge bulk of learning material.
    Structuring the material in the suggestopaedic way; global-partial – partial-global, and global in the part – part in the global, related to the golden proportion.
    As a professional, on one hand, and a personality, on the other hand, the teacher should be a highly-regarded professional, reliable and credible.
    The teacher should have, not play, a hundred percent expectation of positive results (because the teacher is already experienced even from the time of the teacher training course).
    The teacher should love his/her students (of course, not sentimentally but as human beings) and teach them with personal participation through games, songs, a classical type of arts and pleasure.

method for children (preventive Suggestopedia)

The method for Adults includes long sessions without movement, and materials that are appropriate for adults. Children, however, get impacts from “the social suggestive norms” differently and their brains are more delicate than those of adults. Therefore, another method with different materials should be applied to children, which better matches their characteristics. Lessons for children are more incidental and short, preventing the children from the negative pedagogical suggestions of Society. It is important to tell the parents about the method and their roles because they could influence children both negatively and positively, depending on how they support the kids.

side effects

Lozanov claims that the effect of the method is not only in language learning, but also in producing favorable side effects on health, the social and psychological relations, and the subsequent success in other subjects.

unesco's final report on Suggestopedia

recommendations (Extraction)

Made by the Experts from the Working Group on Suggestology as a Learning Methodology Meeting in Sofia, December 11–17, 1978

...1.There is consensus that Suggestopedia is a generally superior teaching method for many subjects and for many types of students, compared with traditional methods. We have arrived at this consensus following a study of the research literature, listening to the testimony of international experts, observing films portraying Suggestopedia instruction and visiting classes in which Suggestopedia is practiced. The films were prepared and the classroom visitations were impressive.

...2.Standards should be set up for the training, certification and maintaining of standards of suggestopedic training.

...3.Different categories of competency of teachers should be used to reflect increasing levels of teaching performance in certification.

...4.Suggestopedic teacher training should be started as soon as possible.

...5.An International Association for Suggestology and Suggestopedia should be set up that is affiliated with UNESCO and should have the assistance and guidance of Dr. Lozanov for training, research, coordination and publication of results.

...6.UNESCO is requested to give its support to all these proposed activities by all possible means and under the existing international regulations.”

criticism

Suggestopedia has been called a "pseudo-science". It strongly depends on the trust that students develop towards the method by simply believing that it works. Lozanov himself admits that Suggestopedia can be compared to a placebo. He argues, however, that placebos are indeed effective. Another point of criticism is brought forward by Baur who claims that the students only receive input by listening, reading and musical-emotional backing, while other important factors of language acquisition are being neglected. Furthermore, several other features of the method, like the 'nonconscious' acquisition of language, or bringing the learner into a childlike state are questioned by critics.

Lukesch claims that Suggestopedia lacks in scientific backing and is criticized by psychologists as being based on pseudoscience.

later variations

Suggestopedia produced four main offshoots. The first was still called Suggestopedia but was developed in eastern Europe and used different techniques from Lozanov's original version. The other three are named Superlearning, Suggestive Accelerated Learning and Teaching (SALT), and Psychopädie. Superlearning and SALT originated in North America, while Psychopädie was developed in West Germany. While all four are slightly different from the original Suggestopedia and from each other, they still share the common traits of music, relaxation, and suggestion.

hell's angels

The Hells Angels Motorcycle Club (HAMC) is a worldwide one-percenter motorcycle club whose members typically ride Harley-Davidson motorcycles and is considered an organized crime syndicate by the U.S. Department of Justice. In the United States and Canada, the Hells Angels are incorporated as the Hells Angels Motorcycle Corporation. Common nicknames for the club are the "H.A.", "Red & White", and "81" (H and A being the eighth and first letters of the alphabet.)

history

The Hells Angels were originally formed in 1948 in Fontana, California through an amalgamation of former members from different motorcycle clubs, such as The Pissed Off Bastards of Bloomington. The Hells Angels' website denies the suggestion that any misfit or malcontent troops are connected with the motorcycle club. However, the website also notes that the name was suggested by Arvid Olson, an associate of the founders, who had served in the Flying Tigers' "Hells Angels" squadron in China during World War II. The name "Hells Angels" was inspired by the typical naming of squadrons, or other fighting groups, with a fierce, death-defying title in both World War I and World War II, e.g., the Flying Tigers (American Volunteer Group) in Burma and China fielded three squadrons of P-40s and the third Squadron was called "Hell's Angels". In 1930, Howard Hughes film Hell's Angels displayed extraordinary and dangerous feats of aviation, and it is believed that the World War II groups who used that name based it on the film.

Some of the early history of the HAMC is not clear, and accounts differ. According to Ralph 'Sonny' Barger, founder of the Oakland chapter, early chapters of the club were founded in San Francisco, Gardena, Fontana, as well as his chapter in Oakland, and other places independently of one another, with the members usually being unaware that there were other Hells Angels clubs.

Other sources[13] claim that the Hells Angels in San Francisco were originally organized in 1953 by Rocky Graves, a Hells Angel member from San Bernardino ("Berdoo") implying that the "Frisco" Hells Angels were very much aware of their forebears. The "Frisco" Hells Angels were reorganized in 1955 with thirteen charter members, Frank Sadilek serving as President, and using the smaller, original logo. The Oakland chapter, at the time headed by Barger used a larger version of the "Death's Head" patch nicknamed the "Barger Larger" which was first used in 1959. It later became the club standard.

The Hells Angels are often depicted in a similarly mythical fashion as other modern-day legends like the James-Younger Gang; free-spirited, iconic, bound by brotherhood and loyalty. At other times, such as in the 1966 Roger Corman film The Wild Angels where they are depicted as violent and nihilistic, they are portrayed as a violent criminal gang and a scourge on society.

The club became prominent within, and established its initial notoriety as part of, the 1960s counterculture movement in San Francisco's Haight-Ashbury scene, London, in England, and elsewhere where it played a part at many of the movement's seminal events. Original members were directly connected to many of the counterculture's primary leaders, such as Ken Kesey and the Merry Pranksters, Allen Ginsberg, Jerry Garcia and The Grateful Dead, Timothy Leary, The Beatles, The Rolling Stones, Mick Farren and Tom Wolfe. The club launched the career of "Gonzo" journalist Hunter S. Thompson.

In recent years, they have been at the center of a highly politicized, worldwide moral panic involving the media, politicians, law enforcement and intelligence agencies.

insignia

The Hells Angels' official website attributes the official "death's head" insignia design to Frank Sadilek, past president of the San Francisco Chapter. The colors and shape of the early-style jacket emblem (prior to 1953) were copied from the insignias of the 85th Fighter Squadron and the 552nd Medium Bomber Squadron.

The Hells Angels utilize a system of patches, similar to military medals. Although the specific meaning of each patch is not publicly known, the patches identify specific or significant actions or beliefs of each biker. The official colors of the Hells Angels are red lettering displayed on a white background—hence the club's nickname "The Red and White". These patches are worn on leather or denim jackets and vests.

Red and white are also used to display the number 81 on many patches, as in "Support 81, Route 81". The 8 and 1 stand for the respective positions in the alphabet of H and A. These are used by friends and supporters of the club, in deference to club rules which purport to restrict the wearing of Hells Angels imagery to club members.

The diamond-shaped one-percenter patch is also used, displaying '1%', in red on a white background with a red merrowed border. The term one-percenter is said to be a response to the American Motorcyclist Association (AMA) comment on the Hollister incident, to the effect that 99% of motorcyclists were law-abiding citizens and the last 1% were outlaws. The AMA has no record of such a statement to the press, and call this story apocryphal.

Most members wear a rectangular patch (again, white background with red letters and a red merrowed border) identifying their respective chapter locations. Another similarly designed patch reads "Hells Angels". When applicable, members of the club wear a patch denoting their position or rank within the organization. The patch is rectangular, and, similarly to the patches described above, displays a white background with red letters and a red merrowed border. Some examples of the titles used are President, Vice President, Secretary, Treasurer, and Sergeant at Arms. This patch is usually worn above the 'club location' patch. Some members also wear a patch with the initials "AFFA", which stands for "Angels Forever; Forever Angels", referring to their lifelong membership in the biker club (i.e., "once a member, always a member").

The book Gangs, written by Tony Thompson (a crime correspondent for The Observer), states that Stephen Cunningham, a member of the Angels, sported a new patch after he recovered from attempting to set a bomb: two Nazi-style SS lightning bolts below the words 'Filthy Few'. Some law enforcement officials claim that the patch is only awarded to those who have committed, or are prepared to commit, murder on behalf of the club. According to a report from the R. v. Bonner and Lindsay case in 2005, another patch, similar to the 'Filthy Few' patch, is the 'Dequiallo' patch. This patch "signifies that the wearer has fought law enforcement on arrest". There is no common convention as to where the patches are located on the members' jacket/vest.

In March 2007, the Hells Angels filed suit against Walt Disney Motion Pictures Group alleging that the film entitled Wild Hogs used both the name and distinctive logo of the Hells Angels Motorcycle Corporation without permission. The suit was eventually voluntarily dismissed, after it received assurances that its references would not appear in the film.

In October 2010, the Hells Angels filed a lawsuit against Alexander McQueen for "misusing its trademark winged death heads symbol" in several items from its Autumn/Winter 2010 collection. The lawsuit is also aimed at Saks Fifth Avenue and Zappos.com, which stock the jacquard box dress and knuckle duster ring which bear the symbol which has been used since at least 1948 and is protected by the U.S. Patent and Trademark Office. A handbag and scarf was also named in lawsuit. The lawyer representing Hells Angels claimed "This isn’t just about money, it’s about membership. If you’ve got one of these rings on, a member might get really upset that you’re an impostor." Saks refused to comment, Zappos had no immediate comment and the company's parent company, PPR, could not be reached for comment. The company settled the case with the Hells Angels after agreeing to remove all of the merchandise featuring the logo from sale on their website, stores and concessions and recalling any of the goods which have already been sold and destroying them.

membership

In order to become a Hells Angels prospect, it has been reported (but not confirmed by the club) that candidates must be a white male, have a valid driver's license, a motorcycle over 750cc and have the right combination of personal qualities. It is said the club excludes child molesters and those individuals who have applied to become police or prison officers.

After a lengthy, phased process, a prospective member is first deemed to be a 'hang-around', indicating that the individual is invited to some club events or to meet club members at known gathering places.

If the hang-around is interested, he may be asked to become an 'associate', a status that usually lasts a year or two. At the end of that stage, he is reclassified as 'prospect', participating in some club activities, but not having voting privileges while he is evaluated for suitability as a full member. The last phase, and highest membership status, is 'Full Membership' or 'Full-Patch'. The term Full-Patch refers to the complete four-piece crest, including the 'Death Head' logo, two rockers (top rocker: 'Hells Angels'; bottom rocker: State or Territory claimed) and the rectangular 'MC' patch below the wing of the Death's Head. Prospects are allowed to wear only a bottom rocker with the State or Territory name along with the rectangular 'MC' patch.

To become a full member, the Prospect must be voted on by the rest of the full club members. Prior to votes being cast, a Prospect usually travels to every chapter in the sponsoring chapter's geographic jurisdiction (state/province/territory) and introduces himself to every Full-Patch member. This process allows each voting member to become familiar with the subject and to ask any questions of concern prior to the vote. Successful admission usually requires more than a simple majority, and some clubs may reject a Prospect for a single dissenting vote. Some form of formal induction follows, wherein the Prospect affirms his loyalty to the club and its members. The final logo patch (top Hells Angels rocker) is then awarded at this initiation ceremony. The step of attaining full membership can be referred to as "being patched".

Even after a member is patched-in, the patches themselves remain the property of HAMC rather than the member. On leaving the Hells Angels, or being ejected, they must be returned to the club.

Contrary to popular opinion, the club was not established as a racially segregated organization.

official chapters

The HAMC acknowledges more than one hundred chapters spread over 29 countries. The first official chapter outside of the U.S. was formed in New Zealand in 1961. Europe did not become home to the Hells Angels until 1969, when two London chapters were formed after the Beatle George Harrison invited some members of the HAMC San Francisco to London. Two people from London visited California, "prospected", and ultimately joined. Two charters were issued on July 30, 1969; one for "South London", the other for "East London", but by 1973 the two charters came together as one, simply called "London". The London Angels provided security at a number of UK Underground festivals including Phun City in 1970 organized by anarchist, International Times writer and lead singer with The Deviants Mick Farren. They even awarded Farren an "approval patch" in 1970 for use on his first solo album Mona, which also featured Steve Peregrin Took (who was credited as "Shagrat the Vagrant"). The 1980s and 1990s saw a major expansion of the club into Canada.

A list of acknowledged chapters can be found on the HAMC club's official website.

criminal activities and incidents

Numerous police and intelligence agencies internationally classify the Hells Angels as one of the "big four" motorcycle gangs, along with the Pagans, Outlaws, and Bandidos, and contend that members carry out widespread violent crimes, drug dealing, trafficking in stolen goods, extortion and are involved in the prostitution industry. Members of the organization have continuously asserted that they are only a group of motorcycle enthusiasts who have joined to ride motorcycles together, to organize social events such as group road trips, fundraisers, parties, and motorcycle rallies and that those crimes are the responsibility of the individuals who carried them out and not the club as a whole.

satyagraha

Satyagraha (/sætɪəɡrɑːhɑː/; Sanskrit: सत्याग्रह satyāgraha), loosely translated as "insistence on truth"- satya (truth); agraha (insistence) "soul force" or "truth force" is a particular philosophy and practice within the broader overall category generally known as nonviolent resistance or civil resistance. The term "satyagraha" was coined and developed by Mahatma Gandhi. He deployed satyagraha in the Indian independence movement and also during his earlier struggles in South Africa for Indian rights. Satyagraha theory influenced Nelson Mandela's struggle in South Africa under apartheid, Martin Luther King, Jr.'s campaigns during the civil rights movement in the United States, and many other social justice and similar movements. Someone who practices satyagraha is a satyagrahi.

origin and meaning of name

The term originated in a competition in the news-sheet Indian Opinion in South Africa in 1906. It was an adaptation by Gandhi of one of the entries in that competition. "Satyagraha" is a Tatpuruṣa compound of the Sanskrit words satya (meaning "truth") and Agraha ("insistence", or "holding firmly to"). For Gandhi, satyagraha went far beyond mere "passive resistance" and became strength in practising non-violent methods. In his words:

Truth (satya) implies love, and firmness (agraha) engenders and therefore serves as a synonym for force. I thus began to call the Indian movement Satyagraha, that is to say, the Force which is born of Truth and Love or non-violence, and gave up the use of the phrase “passive resistance”, in connection with it, so much so that even in English writing we often avoided it and used instead the word “satyagraha” itself or some other equivalent English phrase.

In September 1935, a letter to P.K. Rao, Servants of India Society, Gandhi disputed the proposition that his idea of Civil Disobedience was adapted from the writings of Thoreau.

The statement that I had derived my idea of civil disobedience from the writings of Thoreau is wrong. The resistance to authority in South Africa was well advanced before I got the essay of Thoreau on civil disobedience. But the movement was then known as passive resistance. As it was incomplete, I had coined the word satyagraha for the Gujarati readers. When I saw the title of Thoreau’s great essay, I began the use of his phrase to explain our struggle to the English readers. But I found that even civil disobedience failed to convey the full meaning of the struggle. I therefore adopted the phrase civil resistance. Non-violence was always an integral part of our struggle."

Gandhi described it as follows:

I have also called it love-force or soul-force. In the application of satyagraha, I discovered in the earliest stages that pursuit of truth did not admit of violence being inflicted on one’s opponent but that he must be weaned from error by patience and compassion. For what appears to be truth to the one may appear to be error to the other. And patience means self-suffering. So the doctrine came to mean vindication of truth, not by infliction of suffering on the opponent, but on oneself.

Contrast to “Passive resistance”

Gandhi distinguished between satyagraha and Nonviolent resistance in the following letter:

I have drawn the distinction between passive resistance as understood and practised in the West and satyagraha before I had evolved the doctrine of the latter to its full logical and spiritual extent. I often used “passive resistance” and “satyagraha” as synonymous terms: but as the doctrine of satyagraha developed, the expression “passive resistance” ceases even to be synonymous, as passive resistance has admitted of violence as in the case of suffragettes and has been universally acknowledged to be a weapon of the weak. Moreover, passive resistance does not necessarily involve complete adherence to truth under every circumstance. Therefore it is different from satyagraha in three essentials: Satyagraha is a weapon of the strong; it admits of no violence under any circumstance whatsoever; and it ever insists upon truth. I think I have now made the distinction perfectly clear."

Satyagraha theory

Defining success

Assessing the extent to which Gandhi's ideas of satyagraha were or were not successful in the Indian independence struggle is a complex task. Judith Brown has suggested that "this is a political strategy and technique which, for its outcomes, depends of historical specificities." The view taken by Gandhi differs from the idea that the goal in any conflict is necessarily to defeat the opponent or frustrate the opponent’s objectives, or to meet one’s own objectives despite the efforts of the opponent to obstruct these. In satyagraha, by contrast, these are not the goals. “The Satyagrahi’s object is to convert, not to coerce, the wrong-doer.” Success is defined as cooperating with the opponent to meet a just end that the opponent is unwittingly obstructing. The opponent must be converted, at least as far as to stop obstructing the just end, for this cooperation to take place.

Means and ends

The theory of satyagraha sees means and ends as inseparable. The means used to obtain an end are wrapped up in and attached to that end. Therefore, it is contradictory to try to use unjust means to obtain justice or to try to use violence to obtain peace. As Gandhi wrote: “They say, 'means are, after all, means'. I would say, 'means are, after all, everything'. As the means so the end...”
Gandhi used an example to explain this:

If I want to deprive you of your watch, I shall certainly have to fight for it; if I want to buy your watch, I shall have to pay for it; and if I want a gift, I shall have to plead for it; and, according to the means I employ, the watch is stolen property, my own property, or a donation.

Gandhi rejected the idea that injustice should, or even could, be fought against “by any means necessary” — if you use violent, coercive, unjust means, whatever ends you produce will necessarily embed that injustice. To those who preached violence and called nonviolent actionists cowards, he replied: “I do believe that, where there is only a choice between cowardice and violence, I would advise violence....I would rather have India resort to arms in order to defend her honour than that she should, in a cowardly manner, become or remain a helpless witness to her own dishonour....But I believe that nonviolence is infinitely superior to violence, forgiveness is more manly than punishment.”

Satyagraha versus Duragraha

The essence of Satyagraha is that it seeks to eliminate antagonisms without harming the antagonists themselves, as opposed to violent resistance, which is meant to cause harm to the antagonist. A Satyagrahi therefore does not seek to end or destroy the relationship with the antagonist, but instead seeks to transform or “purify” it to a higher level. A euphemism sometimes used for Satyagraha is that it is a “silent force” or a “soul force” (a term also used by Martin Luther King Jr. during his famous “I Have a Dream” speech). It arms the individual with moral power rather than physical power. Satyagraha is also termed a “universal force,” as it essentially “makes no distinction between kinsmen and strangers, young and old, man and woman, friend and foe.”

Gandhi contrasted satyagraha (holding on to truth) with “duragraha” (holding on by force), as in protest meant more to harass than enlighten opponents. He wrote: “There must be no impatience, no barbarity, no insolence, no undue pressure. If we want to cultivate a true spirit of democracy, we cannot afford to be intolerant. Intolerance betrays want of faith in one's cause.”
Civil disobedience and non-cooperation as practised under Satyagraha are based on the “law of suffering”, a doctrine that the endurance of suffering is a means to an end. This end usually implies a moral upliftment or progress of an individual or society. Therefore, non-cooperation in Satyagraha is in fact a means to secure the cooperation of the opponent consistently with truth and justice.

Satyagraha in large-scale conflict

When using satyagraha in a large-scale political conflict involving civil disobedience, Gandhi believed that the satyagrahis must undergo training to ensure discipline. He wrote that it is “only when people have proved their active loyalty by obeying the many laws of the State that they acquire the right of Civil Disobedience."

He therefore made part of the discipline that satyagrahis:

1. appreciate the other laws of the State and obey them voluntarily
2. tolerate these laws, even when they are inconvenient
3. be willing to undergo suffering, loss of property, and to endure the suffering that might be inflicted on family and friends

This obedience has to be not merely grudging, but extraordinary:

…an honest, respectable man will not suddenly take to stealing whether there is a law against stealing or not, but this very man will not feel any remorse for failure to observe the rule about carrying headlights on bicycles after dark.… But he would observe any obligatory rule of this kind, if only to escape the inconvenience of facing a prosecution for a breach of the rule. Such compliance is not, however, the willing and spontaneous obedience that is required of a Satyagrahi.

Principles for satyagrahis

Gandhi envisioned satyagraha as not only a tactic to be used in acute political struggle, but as a universal solvent for injustice and harm. He felt that it was equally applicable to large-scale political struggle and to one-on-one interpersonal conflicts and that it should be taught to everyone.

He founded the Sabarmati Ashram to teach satyagraha. He asked satyagrahis to follow the following principles (Yamas described in Yoga Sutra):

1. Nonviolence (ahimsa)
2. Truth — this includes honesty, but goes beyond it to mean living fully in accord with and in devotion to that which is true
3. Non-stealing
4. Chastity (brahmacharya) — this includes sexual chastity, but also the subordination of other sensual desires to the primary devotion to truth
5. Non-possession (not the same as poverty)
6. Body-labor or bread-labor
7. Control of the palate
8. Fearlessness
9. Equal respect for all religions
10. Economic strategy such as boycotts (swadeshi)
11. Freedom from untouchability

On another occasion, he listed seven rules as “essential for every Satyagrahi in India”:

1. must have a living faith in God
2. must believe in truth and non-violence and have faith in the inherent goodness of human nature which he expects to evoke by suffering in the satyagraha effort
3. must be leading a chaste life, and be willing to die or lose all his possessions
4. must be a habitual khadi wearer and spinner
5. must abstain from alcohol and other intoxicants
6. must willingly carry out all the rules of discipline that are issued
7. must obey the jail rules unless they are specially devised to hurt his self respect

Rules for satyagraha campaigns

Gandhi proposed a series of rules for satyagrahis to follow in a resistance campaign:

1. harbour no anger
2. suffer the anger of the opponent
3. never retaliate to assaults or punishment; but do not submit, out of fear of punishment or assault, to an order given in anger
4. voluntarily submit to arrest or confiscation of your own property
5. if you are a trustee of property, defend that property (non-violently) from confiscation with your life
6. do not curse or swear
7. do not insult the opponent
8. neither salute nor insult the flag of your opponent or your opponent’s leaders
9. if anyone attempts to insult or assault your opponent, defend your opponent (non-violently) with your life
10. as a prisoner, behave courteously and obey prison regulations (except any that are contrary to self-respect)
11. as a prisoner, do not ask for special favourable treatment
12. as a prisoner, do not fast in an attempt to gain conveniences whose deprivation does not involve any injury to your self-respect
13. joyfully obey the orders of the leaders of the civil disobedience action
14. do not pick and choose amongst the orders you obey; if you find the action as a whole improper or immoral, sever your connection with the action entirely
15. do not make your participation conditional on your comrades taking care of your dependents while you are engaging in the campaign or are in prison; do not expect them to provide such support
16. do not become a cause of communal quarrels
17. do not take sides in such quarrels, but assist only that party which is demonstrably in the right; in the case of inter-religious conflict, give your life to protect (non-violently) those in danger on either side
18. avoid occasions that may give rise to communal quarrels
19. do not take part in processions that would wound the religious sensibilities of any community

Satyagraha and the civil rights movement in the United States

Satyagraha theory also influenced many other movements of civil resistance. For example, Martin Luther King, Jr. wrote in his autobiography about Gandhi's influence on his developing ideas regarding the civil rights movement in the United States:

Like most people, I had heard of Gandhi, but I had never studied him seriously. As I read I became deeply fascinated by his campaigns of nonviolent resistance. I was particularly moved by his Salt March to the Sea and his numerous fasts. The whole concept of Satyagraha (Satya is truth which equals love, and agraha is force; Satyagraha, therefore, means truth force or love force) was profoundly significant to me. As I delved deeper into the philosophy of Gandhi, my skepticism concerning the power of love gradually diminished, and I came to see for the first time its potency in the area of social reform. ... It was in this Gandhian emphasis on love and nonviolence that I discovered the method for social reform that I had been seeking.

Satyagraha and the Jewish Holocaust

In view of the Nazi persecution of the Jews in Germany, Gandhi offered satyagraha as a method of combating oppression and genocide, stating:

If I were a Jew and were born in Germany and earned my livelihood there, I would claim Germany as my home even as the tallest Gentile German might, and challenge him to shoot me or cast me in the dungeon; I would refuse to be expelled or to submit to discriminating treatment. And for doing this I should not wait for the fellow Jews to join me in civil resistance, but would have confidence that in the end the rest were bound to follow my example. If one Jew or all the Jews were to accept the prescription here offered, he or they cannot be worse off than now. And suffering voluntarily undergone will bring them an inner strength and joy. the calculated violence of Hitler may even result in a general massacre of the Jews by way of his first answer to the declaration of such hostilities. But if the Jewish mind could be prepared for voluntary suffering, even the massacre I have imagined could be turned into a day of thanksgiving and joy that Jehovah had wrought deliverance of the race even at the hands of the tyrant. For to the God-fearing, death has no terror.

When Gandhi was criticized for these statements, he responded in another article entitled “Some Questions Answered”:

Friends have sent me two newspaper cuttings criticizing my appeal to the Jews. The two critics suggest that in presenting non-violence to the Jews as a remedy against the wrong done to them, I have suggested nothing new... What I have pleaded for is renunciation of violence of the heart and consequent active exercise of the force generated by the great renunciation.”

In a similar vein, anticipating a possible attack on India by Japan during World War II, Gandhi recommended satyagraha as a means of national defense (what is now sometimes called "defence by civil resistance" or "social defence"):

…there should be unadulterated non-violent non-cooperation, and if the whole of India responded and unanimously offered it, I should show that, without shedding a single drop of blood, Japanese arms – or any combination of arms – can be sterilized. That involves the determination of India not to give quarter on any point whatsoever and to be ready to risk loss of several million lives. But I would consider that cost very cheap and victory won at that cost glorious. That India may not be ready to pay that price may be true. I hope it is not true, but some such price must be paid by any country that wants to retain its independence. After all, the sacrifice made by the Russians and the Chinese is enormous, and they are ready to risk all. The same could be said of the other countries also, whether aggressors or defenders. The cost is enormous. Therefore, in the non-violent technique I am asking India to risk no more than other countries are risking and which India would have to risk even if she offered armed resistance.

Gandhi's combination of renunciation of violence with active acceptance of suffering also received support from Jewish thinkers. Psychiatrist Victor Frankl and psychologist Bruno Bettelheim, both Holocaust survivors, confirmed Gandhi's experience that individuals who neither submit passively nor retaliate to violence find in themselves a new sense of strength, dignity, and courage. Gandhi's approach has been compared with Frankl's.

cats

The domestic cat (Felis catus or Felis silvestris catus) is a small, usually furry, domesticated, carnivorous mammal. It is often called the housecat when kept as an indoor pet, or simply the cat when there is no need to distinguish it from other felids and felines. Cats are valued by humans for companionship and ability to hunt vermin and household pests. They are primarily nocturnal.


Cats are similar in anatomy to the other felids, with strong, flexible bodies, quick reflexes, sharp retractable claws, and teeth adapted to killing small prey. Cat senses fit a crepuscular and predatory ecological niche. Cats can see in near darkness, and hear sounds too faint or too high in frequency for human ears, such as those made by the usual prey of cats (particularly mice and other rodents). Like most mammals, cats have a much better sense of smell than humans.


Despite being solitary hunters, cats are a social species, and cat communication includes the use of a variety of vocalizations (meowing, purring, trilling, hissing, growling and grunting) as well as pheromones and types of cat-specific body language.


Cats have a rapid breeding rate. Under controlled breeding, they can be bred and shown as registered pedigree pets, a hobby known as cat fancy. Failure to control the breeding of pet cats by spaying and neutering and the abandonment of former household pets has resulted in large numbers of feral cats worldwide, with a population of up to 60 million of these animals in the United States alone, while in Japan they are caught and disposed of.


Since cats were cult animals in ancient Egypt, they were commonly believed to have been domesticated there, but there may have been instances of domestication as early as the Neolithic.


A genetic study in 2007 revealed that all domestic cats are descended from as few as five female African wildcats (Felis silvestris lybica) c. 8000 BCE, in the Middle East. Cats are currently the most popular pet in the world, and now found almost everywhere in the world where people live.


nomenclature and etymology


The English word cat (Old English catt) is in origin a loanword, introduced to many languages of Europe from Latin cattus and Byzantine Greek κάτια, including Portuguese and Spanish gato, French chat, German Katze, Lithuanian katė and Old Church Slavonic kotka, among others.The ultimate source of the word is Afroasiatic, presumably from Late Egyptian čaute, the feminine of čaus "wildcat".The word was introduced, together with the domestic animal itself, to the Roman Republic by the 1st century BCE. An alternative word with cognates in many languages is English puss (pussycat). Attested only from the 16th century, it may have been introduced from Dutch poes or from Low German puuskatte, related to Swedish kattepus, or Norwegian pus, pusekatt. The etymology of this word is unknown, but it appears to reflect the native Germanic name of the animal.


A group of cats is referred to as a "clowder", a male cat is called a "tom" (or a "gib", if neutered), a female is called a "molly" or (especially among breeders) a "queen", and a pre-pubescent juvenile is referred to as a "kitten". The male progenitor of a cat, especially a pedigreed cat, is its "sire", and its female progenitor is its "dam". An immature cat is called a "kitten". In Early Modern English, the word kitten was interchangeable with the now-obsolete word catling.


A pedigreed cat is one whose ancestry is recorded by a cat fancier organization. A purebred cat cat is one whose ancestry contains only individuals of the same breed. Many pedigreed and especially purebred cats are exhibited as show cats. Cats of unrecorded, mixed ancestry are referred to as domestic short-haired ordomestic long-haired cats, by coat type, or commonly as random-bred, moggies (chiefly British)), or (using terms borrowed from dog breeding) mongrels or mutt-cats.


While the African wildcat is the ancestral species from which domestic cats are descended, there are several intermediate stages between domestic pet and pedigree cats on the one hand and those entirely wild animals on the other. The semi-feral cat is a mostly outdoor cat that is not owned by any one individual, but is generally friendly to people and may be fed by several households. Feral cats are associated with human habitation areas and may be fed by people or forage in rubbish, but are wary of human interaction.


taxonomy and evolution


The felids are a rapidly evolving family of mammals that share a common ancestor only 10–15 million years ago, and include, in addition to the domestic cat, lions, tigers, cougars, and many others. Within this family, domestic cats (Felis catus) are part of the genus Felis, which is a group of small cats containing approximately seven species (depending upon classification scheme). Members of the genus are found worldwide and include the jungle cat (Felis chaus) of southeast Asia, European wildcat (F. silvestris silvestris), African wildcat (F. s. lybica), the Chinese mountain cat (F. bieti), and the Arabian sand cat (F. margarita), among others.


All the cats in this genus share a common ancestor that probably lived around 6–7 million years ago in Asia. The exact relationships within the Felidae are close but still uncertain, e.g. the Chinese mountain cat is sometimes classified (under the name Felis silvestris bieti) as a subspecies of the wildcat, like an African variety F. S. lybica. As domestic cats are little altered from wildcats, they can readily interbreed. This hybridization poses a danger to the genetic distinctiveness of wildcat populations, particularly in Scotland and Hungary, and possibly also the Iberian Peninsula.


The domestic cat was first classified as Felis catus by Carolus Linnaeus in the tenth edition of his Systema Naturae in 1758. However, because of modern phylogenetics, domestic cats are now usually regarded as another subspecies of the wildcat, Felis silvestris. This has resulted in mixed usage of the terms, as the domestic cat can be called by its subspecies name, Felis silvestris catus. Wildcats have also been referred to as various subspecies of F. catus, but in 2003 the International Commission on Zoological Nomenclature fixed the name for wildcats as F. silvestris. The most common name in use for the domestic cat remains F. catus, following a convention for domesticated animals of using the earliest (the senior) synonym proposed. Sometimes the domestic cat has been called Felis domesticus or Felis domestica, as proposed by German naturalist J. C. P. Erxleben in 1777, but these are not valid taxonomic names and have only rarely been used in scientific literature, because Linnaeus's binomial takes precedence.


Cats have either a mutualistic or commensal relationship with humans. However, in comparison to dogs, cats have not undergone major changes during the domestication process, as the form and behavior of the domestic cat are not radically different from those of wildcats, and domestic cats are perfectly capable of surviving in the wild. This limited evolution during domestication means that domestic cats tend to interbreed freely with wild relatives, which distinguishes them from other domesticated animals. Fully domesticated house cats also often interbreed with feral F. catus populations. However, several natural behaviors and characteristics of wildcats may have pre-adapted them for domestication as pets. These traits include their small size, social nature, obvious body language, love of play, and relatively high intelligence; they may also have an inborn tendency towards tameness.


There are two main theories about how cats were domesticated. In one, people deliberately tamed cats in a process of artificial selection, as they were useful predators of vermin. However, this has been criticized as implausible, because there may have been little reward for such an effort: Cats generally do not carry out commands and, although they do eat rodents, other species such as ferrets or terriers may be better at controlling these pests. The alternative idea is that cats were simply tolerated by people and gradually diverged from their wild relatives through natural selection, as they adapted to hunting the vermin found around humans in towns and villages.


genetics


The domesticated cat and its closest wild ancestor are both diploid organisms that possess 38 chromosomes and roughly 20,000 genes. About 250 heritable genetic disorders have been identified in cats, many similar to human inborn errors. The high level of similarity among the metabolisms of mammals allows many of these feline diseases to be diagnosed using genetic tests that were originally developed for use in humans, as well as the use of cats as animal models in the study of the human diseases.


anatomy


Domestic cats are similar in size to the other members of the genus Felis, typically weighing between 4 kilograms (8.8 lb) and 5 kilograms (11 lb). However, some breeds, such as the Maine Coon, can occasionally exceed 11 kilograms (25 lb). Conversely, very small cats (less than 1.8 kilograms (4.0 lb)) have been reported. The world record for the largest cat is 21.297 kilograms (46 lb 15.2 oz). The smallest adult cat ever officially recorded weighed around 1.36 kilograms (3 lb). Cats average about 23–25 centimeters (9–10 in) in height and 46 centimeters (18.1 in) in head/body length (males being larger than females), with tails averaging 30 centimeters (11.8 in) in length.


Cats have 7 cervical vertebrae like almost all mammals, 13 thoracic vertebrae (humans have 12), 7 lumbar vertebrae (humans have 5), 3 sacral vertebrae like most mammals (humans have 5 because of their bipedal posture), and a variable number of caudal vertebrae in the tail (humans retain 3 to 5 caudal vertebrae, fused into an internal coccyx).The extra lumbar and thoracic vertebrae account for the cat's spinal mobility and flexibility. Attached to the spine are 13 ribs, the shoulder, and the pelvis.Unlike human arms, cat forelimbs are attached to the shoulder by free-floating clavicle bones, which allow them to pass their body through any space into which they can fit their heads.


The cat skull is unusual among mammals in having very large eye sockets and a powerful and specialized jaw. Within the jaw, cats have teeth adapted for killing prey and tearing meat. When it overpowers its prey, a cat delivers a lethal neck bite with its two long canine teeth, inserting them between two of the prey's vertebrae and severing its spinal cord, causing irreversible paralysis and death. Compared to other felines, domestic cats have narrowly spaced canine teeth; which is an adaptation to their preferred prey of small rodents, which have small vertebrae. The premolar and first molar together compose the carnassial pair on each side of the mouth, which efficiently shears meat into small pieces, like a pair of scissors. These are vital in feeding, since cats' small molars cannot chew food effectively.


Cats, like dogs, are digitigrades. They walk directly on their toes, with the bones of their feet making up the lower part of the visible leg. Cats are capable of walking very precisely, because like all felines they directly register; that is, they place each hind paw (almost) directly in the print of the corresponding forepaw, minimizing noise and visible tracks. This also provides sure footing for their hind paws when they navigate rough terrain. Unlike most mammals, when cats walk, they use a "pacing" gait; that is, they move the two legs on one side of the body before the legs on the other side. This trait is shared with camels and giraffes. As a walk speeds up into a trot, a cat's gait will change to be a "diagonal" gait, similar to that of most other mammals (and many other land animals, such as lizards): the diagonally opposite hind and forelegs will move simultaneously.


Like almost all members of the Felidae family, cats have protractable and retractable claws. In their normal, relaxed position the claws are sheathed with the skin and fur around the paw's toe pads. This keeps the claws sharp by preventing wear from contact with the ground and allows the silent stalking of prey. The claws on the forefeet are typically sharper than those on the hind feet. Cats can voluntarily extend their claws on one or more paws. They may extend their claws in hunting or self-defense, climbing, kneading, or for extra traction on soft surfaces. Most cats have five claws on their front paws, and four on their rear paws. The fifth front claw (the dewclaw) is proximal to the other claws. More proximally, there is a protrusion which appears to be a sixth "finger". This special feature of the front paws, on the inside of the wrists, is the carpal pad, also found on the paws of big cats and of dogs. It has no function in normal walking, but is thought to be an anti-skidding device used while jumping. Some breeds of cats are prone to polydactyly (extra toes and claws). These are particularly common along the northeast coast of North America.


physiology


As cats are familiar and easily kept animals, their physiology has been particularly well studied; it generally resembles that of other carnivorous mammals but displays several unusual features probably attributable to cats' descent from desert-dwelling species. For instance, cats are able to tolerate quite high temperatures: Humans generally start to feel uncomfortable when their skin temperature passes about 44.5 °C (112 °F), but cats show no discomfort until their skin reaches around 52 °C (126 °F), and can tolerate temperatures of up to 56 °C (133 °F) if they have access to water.


Cats conserve heat by reducing the flow of blood to their skin and lose heat by evaporation through their mouth. They do not sweat, and pant for heat relief only at very high temperatures (but may also pant when stressed). Unusually, a cat's body temperature does not vary throughout the day; this is part of cats' general lack of circadian rhythms and may reflect their tendency to be active both during the day and at night. Cats' feces are comparatively dry and their urine is also highly concentrated, both of which are adaptations that allow cats to retain as much fluid as possible. Their kidneys are so efficient that cats can survive on a diet consisting only of meat, with no additional water, and can even rehydrate by drinking seawater.


Cats are obligate carnivores: Their physiology has evolved to efficiently process meat, and they have difficulty digesting plant matter. In contrast to omnivores such as rats, which only require about 4% protein in their diet, about 20% of a cat's diet must be protein. Cats are unusually dependent on a constant supply of the amino acid arginine, and a diet lacking arginine causes marked weight loss and can be rapidly fatal. Another unusual feature is that the cat also cannot produce the amino acid taurine, with taurine deficiency causing macular degeneration, wherein the cat's retina slowly degenerates, causing irreversible blindness. Since cats tend to eat all of their prey, they obtain minerals by digesting animal bones, and a diet composed only of meat may cause calcium deficiency.


A cat's gastrointestinal tract is also adapted to meat eating, being much shorter than that of omnivores and having low levels of several of the digestive enzymes that are needed to digest carbohydrates. These traits severely limit the cat's ability to digest and use plant-derived nutrients, as well as certain fatty acids. Despite the cat's meat-oriented physiology, several vegetarian or vegan cat foods have been marketed that are supplemented with chemically synthesized taurine and other nutrients, in attempts to produce a complete diet. However, some of these products still fail to provide all the nutrients that cats require, and diets containing no animal products pose the risk of causing severe nutritional deficiencies.


Cats also eat grass occasionally. Proposed explanations include that grass is a source of folic acid or dietary fiber.


senses


Cats have excellent night vision and can see at only one-sixth the light level required for human vision.This is partly the result of cat eyes having a tapetum lucidum, which reflects any light that passes through the retina back into the eye, thereby increasing the eye's sensitivity to dim light. Another adaptation to dim light is the large pupils of cats' eyes. Unlike some big cats, such as tigers, domestic cats have slit pupils. These slit pupils can focus bright light without chromatic aberration, and are needed since the domestic cat's pupils are much larger, relative to their eyes, than the pupils of the big cats. Indeed, at low light levels a cat's pupils will expand to cover most of the exposed surface of its eyes. However, domestic cats have rather poor color vision and (like most non-primate mammals) have only two types of cones, optimized for sensitivity to blue and yellowish green; they have limited ability to distinguish between red and green, although they can achieve this in some conditions.


Cats have excellent hearing and can detect an extremely broad range of frequencies. They can hear higher-pitched sounds than either dogs or humans, detecting frequencies from 55 Hz up to 79 kHz, a range of 10.5 octaves; while humans can only hear from 31 Hz up to 18 kHz, and dogs hear from 67 Hz to 44 kHz, which are both ranges of about 9 octaves. Cats do not use this ability to hear ultrasound for communication but it is probably important in hunting, since many species of rodents make ultrasonic calls. Cat hearing is also extremely sensitive and is among the best of any mammal, being most acute in the range of 500 Hz to 32 kHz. This sensitivity is further enhanced by the cat's large movable outer ears (their pinnae), which both amplify sounds and help a cat sense the direction from which a noise is coming.


Cats have an acute sense of smell, which is due in part to their well-developed olfactory bulb and also to a large surface of olfactory mucosa, in cats this mucosa is about 5.8 cm2 in area, which is about twice that of humans and only 1.7-fold less than the average dog. Cats are very sensitive to pheromones such as 3-mercapto-3-methylbutan-1-ol, which they use to communicate through urine spraying and marking with scent glands. Cats also respond strongly to plants that contain nepetalactone, especially catnip, as they can detect that substance at less than one part per billion. This response is also produced by other plants, such as silver vine (''Actinidia polygama) and the herb valerian; it may be caused by the smell of these plants mimicking a pheromone and stimulating cats' social or sexual behaviors.


Cats have relatively few taste buds compared to humans. Owing to a mutation in an early cat ancestor, one of two genes necessary to taste sweetness may have been lost by the cat family. Their taste buds instead respond to amino acids, bitter tastes and acids. To aid with navigation and sensation, cats have dozens of movable vibrissae (whiskers) over their body, especially their face. These provide information on the width of gaps and on the location of objects in the dark, both by touching objects directly and by sensing air currents; they also trigger protective blink reflexes to protect the eyes from damage.


health


The average life expectancy for male indoor cats at birth is around 12 to 14 years, with females usually living a year or two longer. However, there have been reports of cats reaching into their 30s, with the oldest known cat, Creme Puff, dying at a verified age of 38. Feline life expectancy has increased significantly in recent decades. Having a cat neutered or spayed confers some health benefits, since castrated males cannot develop testicular cancer, spayed females cannot develop uterine or ovarian cancer, and both have a reduced risk of mammary cancer. The lifespan of feral cats is hard to determine accurately, although one study reported a median age of 4.7 years, with a range between 0 to 8.3 years.


diseases


Cats can suffer from a wide range of health problems, including infectious diseases, parasites, injuries and chronic disease. Vaccinations are available for many of these diseases, and domestic cats are regularly given treatments to eliminate parasites such as worms and fleas.


poisoning


In addition to obvious dangers such as rodenticides, insecticides and herbicides, cats may be poisoned by many chemicals that are usually considered safe by pet owners. This is because their livers are less effective at some forms of detoxification than those of many other animals, including humans and dogs.Some of the most common causes of poisoning in cats are antifreeze and rodent baits. It has also been suggested that cats may be particularly sensitive to environmental pollutants. When a cat has a sudden or prolonged serious illness without any obvious cause, it is possible that it has been exposed to a toxin.


Human medicines should never be given to cats. For example, the painkiller paracetamol (also called acetaminophen, sold as Tylenol and Panadol) is extremely toxic to cats: even very small doses need immediate treatment and can be fatal. Even aspirin, which is sometimes used to treat arthritis in cats, is much more toxic to them than to humans and must be administered cautiously. Similarly, application of minoxidil (Rogaine) to the skin of cats, either accidentally or by well-meaning owners attempting to counter loss of fur, has sometimes been fatal. Essential oils can be toxic to cats and there have been reported cases of serious illnesses caused by tea tree oil, including flea treatments and shampoos containing it.


Other common household substances that should be used with caution around cats include mothballs and other naphthalene products. Phenol-based products (e.g. Pine-Sol, Dettol (Lysol) or hexachlorophene) are often used for cleaning and disinfecting near cats' feeding areas or litter boxes but these can sometimes be fatal. Ethylene glycol, often used as an automotive antifreeze, is particularly appealing to cats, and as little as a teaspoonful can be fatal. Some human foods are toxic to cats; for example chocolate can cause theobromine poisoning, although (unlike dogs) few cats will eat chocolate. Large amounts of onions or garlic are also poisonous to cats. Many houseplants are also dangerous, such as Philodendron species and the leaves of the Easter lily (Lilium longiflorum), which can cause permanent and life-threatening kidney damage.


behavior


Free-ranging cats are active both day and night, although they tend to be slightly more active at night. The timing of cats' activity is quite flexible and varied, which means that house cats may be more active in the morning and evening (crepuscular behavior), as a response to greater human activity at these times. Although they spend the majority of their time in the vicinity of their home, housecats can range many hundreds of meters from this central point, and are known to establish territories that vary considerably in size, in one study ranging from 7 to 28 hectares (17 to 69 acres). Cats conserve energy by sleeping more than most animals, especially as they grow older. The daily duration of sleep varies, usually 12–16 hours, with 13–14 being the average. Some cats can sleep as much as 20 hours in a 24-hour period. The term"cat nap" for a short rest refers to the cat's tendency to fall asleep (lightly) for a brief period. While asleep, cats experience short periods of rapid eye movement sleep often accompanied by muscle twitches, which suggests that they are dreaming.


sociability


Although wildcats are solitary, the social behavior of domestic cats is much more variable and ranges from widely dispersed individuals to feral cat colonies that form around a food source, based on groups of co-operating females. Within such groups one cat is usually dominant over the others. Each cat in a colony holds a distinct territory, with sexually active males having the largest territories, which are about ten times larger than those of female cats and may overlap with several females' territories. These territories are marked by urine spraying, by rubbing objects at head height with secretions from facial glands, and by defecation. Between these territories are neutral areas where cats watch and greet one another without territorial conflicts. Outside these neutral areas, territory holders usually chase away stranger cats, at first by staring, hissing, and growling, and if that does not work, by short but noisy and violent attacks. Despite some cats cohabiting in colonies, cats do not have a social survival strategy, or a pack mentality and always hunt alone.


Domestic cats use many vocalizations for communication, including purring, trilling, hissing, growling/snarling, grunting, and several different forms of meowing.By contrast, feral cats are generally silent. Their types of body language, including position of ears and tail, relaxation of whole body, and kneading of paws, are all indicators of mood. The tail and ears are particularly important social signal mechanisms in cats, e.g. with a raised tail acting as a friendly greeting, and flattened ears indicating hostility. Tail-raising also indicates the cat's position in the group's social hierarchy, with dominant individuals raising their tails less often than subordinate animals. Nose-to-nose touching is also a common greeting and may be followed by social grooming, which is solicited by one of the cats raising and tilting its head.


However, some pet cats are poorly socialized. In particular, older cats may show aggressiveness towards newly arrived kittens, which may include biting and scratching; this type of behavior is known as feline asocial aggression.


For cats, life in proximity to humans and other animals kept by them amounts to a "symbiotic social adaptation". They may express great affection towards their human (and even other) companions, especially if they psychologically imprint on them at a very young age and are treated with consistent affection. It has been suggested that, ethologically, the human keeper of a cat functions as a sort of surrogate for the cat's mother, and that adult housecats live their lives in a kind of extended kittenhood, a form of behavioral neoteny. It has even been theorized that the high-pitched sounds housecats make to solicit food may mimic the cries of a hungry human infant, making them particularly hard for humans to ignore.


grooming


Cats are known for their cleanliness, spending many hours licking their coats. The cat's tongue has backwards-facing spines about 500 micrometers long, which are called papillae. These are quite rigid, as they contain keratin. These spines allow cats to groom themselves by licking their fur, with the rows of papillae acting like a hairbrush. Some cats, particularly longhaired cats, occasionally regurgitate hairballs of fur that have collected in their stomachs from grooming. These clumps of fur are usually sausage-shaped and about two to three centimeters long. Hairballs can be prevented with remedies that ease elimination of the hair through the gut, as well as regular grooming of the coat with a comb or stiff brush. Some cats can develop a compulsive behavior known as psychogenic alopecia, or excessive grooming.


fighting


Among domestic cats, males are more likely to fight than females. Among feral cats, the most common reason for cat fighting is competition between two males to mate with a female. In such cases, most fights will be won by the heavier male. Another common reason for fighting in domestic cats is the difficulty of establishing territories within a small home. Female cats will also fight over territory or to defend their kittens. Spaying females and neutering males will decrease or eliminate this behavior in many cases, suggesting that the behavior is linked to sex hormones.


When fighting, cats make themselves appear more impressive and threatening by raising their fur, arching their backs, and turning sideways, thus increasing their apparent size. Often, the ears are pointed down and back to avoid damage to the inner ear and potentially listen for any changes behind them while focused forward. They may also vocalize loudly and bare their teeth in an effort to further intimidate their opponent. Fights usually comprise of grappling and delivering powerful slaps to the face and body with the forepaws as well as bites. Cats will also throw themselves to the ground in a defensive posture to rake their opponent's belly with their powerful hind legs. Serious damage is rare as the fights are usually short in duration, with the loser running away with little more than a few scratches to the face and ears. However, fights for mating rights are typically more severe and injuries may include deep puncture wounds and lacerations. Normally, serious injuries from fighting will be limited to infections of scratches and bites, though these can occasionally kill cats if untreated. In addition, bites are probably the main route of transmission of feline immunodeficiency virus (FIV). Sexually active males will usually be involved in many fights during their lives, and often have decidedly battered faces with obvious scars and cuts to the ears and nose.


hunting and feeding


Cats feed on small prey, primarily birds and rodents. Feral cats and house cats that are free-fed tend to consume many small meals in a single day, although the frequency and size of meals varies between individuals. Cats use two hunting strategies, either stalking prey actively, or waiting in ambush until an animal comes close enough to be captured. Although it is not certain, the type of strategy used may depend on the prey species in the area, with for example, cats waiting in ambush outside burrows, but tending to actively stalk birds.


Most breeds of cat have a noted fondness for settling in high places, or perching. In the wild, a higher place may serve as a concealed site from which to hunt; domestic cats may strike prey by pouncing from such a perch as a tree branch, as does a leopard. Other possible explanations include that height gives the cat a better observation point, allowing it to survey its territory. During a fall from a high place, a cat can reflexively twist its body and right itself using its acute sense of balance and flexibility. This is known as the cat righting reflex. An individual cat always rights itself in the same way, provided it has the time to do so, during a fall. The height required for this to occur is around 90 cm (3 feet). Cats without a tail (e.g. Manx cats) also have this ability, since a cat mostly moves its hind legs and relies on conservation of angular momentum to set up for landing, and the tail is in fact little used for this feat. This leads to the proverb "a cat always lands on its feet".


One poorly understood element of cat hunting behavior is the presentation of prey to human owners. Ethologist Paul Leyhausen proposed that cats adopt humans into their social group, and share excess kill with others in the group according to the local pecking order, in which humans are placed at or near the top. Anthropologist and zoologist Desmond Morris, in his 1986 book Catwatching, suggests that when cats bring home mice or birds, they are attempting to teach their human to hunt, or trying to help their human as if feeding "an elderly cat, or an inept kitten". Morris's theory is inconsistent with the fact that male cats also bring home prey, despite males having no involvement with raising kittens.


Domestic cats select food based on its temperature, smell and texture, strongly disliking chilled foods and responding most strongly to moist foods rich in amino acids, which are similar to meat. Cats may reject novel flavors (a response termed neophobia) and learn quickly to avoid foods that have tasted unpleasant in the past. They may also avoid sugary foods and milk; since they are lactose intolerant, these sugars are not easily digested and may cause soft stools or diarrhea. They can also develop odd eating habits. Some cats like to eat or chew on other things, most commonly wool, but also plastic, paper, string, aluminum foil/Christmas tree tinsel, or even coal. This condition is called pica and can threaten their health, depending on the amount and toxicity of the items eaten.


Since cats cannot fully close their lips around something to create suction, they use a lapping method with the tongue to draw liquid upwards into their mouths. Lapping at a rate of four times a second, the cat touches the smooth tip of its tongue to the surface of the water, and quickly retracts it, drawing water upwards.


play


Domestic cats, especially young kittens, are known for their love of play. This behavior mimics hunting and is important in helping kittens learn to stalk, capture, and kill prey. Cats will also engage in play fighting, with each other and with humans. This behavior may be a way for cats to practice the skills needed for real combat, and might also reduce any fear they associate with launching attacks on other animals.


Owing to the close similarity between play and hunting, cats prefer to play with objects that resemble prey, such as small furry toys that move rapidly, but rapidly lose interest (they become habituated) in a toy they have played with before.Cats also tend to play with toys more when they are hungry. String is often used as a toy, but if it is eaten it can become caught at the base of the cat's tongue and then move into the intestines, a medical emergency which can cause serious illness, even death. Owing to the risks posed by cats eating string, it is sometimes replaced with a laser pointer's dot, which cats may chase. This is a tertiary source that clearly includes information from other sources but does not name them. While concerns have been raised about the safety of these lasers, John Marshall, an ophthalmologist at St Thomas' Hospital, has stated that it would be "virtually impossible" to blind a cat with a laser pointer.


reproduction


Female cats are seasonally polyestrous, which means they may have many periods of heat over the course of a year, the season beginning in spring and ending in late autumn. Heat periods occur about every two weeks and last about 4 to 7 days. Multiple males will be attracted to a female in heat. The males will fight over her, and the victor wins the right to mate. At first, the female will reject the male, but eventually the female will allow the male to mate. The female will utter a loud yowl as the male pulls out of her. This is because a male cat's penis has a band of about 120–150 backwards-pointing penile spines, which are about one millimeter long; upon withdrawal of the penis, the spines rake the walls of the female's vagina, which is a trigger for ovulation. This act also occurs to clear the vagina of other sperm in the context of a second (or more) mating, thus giving the later males a larger chance of conception.


After mating, the female will wash her vulva thoroughly. If a male attempts to mate with her at this point, the female will attack him. After about 20 to 30 minutes, once the female is finished grooming, the cycle will repeat.


Because ovulation is not always triggered by a single mating, females may not be impregnated by the first male with which they mate. Furthermore, cats are superfecund; that is, a female may mate with more than one male when she is in heat, with the result that different kittens in a litter may have different fathers.


The gestation period for cats is between 64–67 days, with an average length of 66 days. The size of a litter averages three to five kittens, with the first litter usually smaller than subsequent litters. Kittens are weaned at between six and seven weeks, and cats normally reach sexual maturity at 5–10 months (females) and to 5–7 months (males), although this can vary depending on breed. Females can have two to three litters per year, so may produce up to 150 kittens in their breeding span of around ten years.


Cats are ready to go to new homes at about 12 weeks old, or when they are ready to leave their mother. Cats can be surgically sterilized (spayed or castrated) as early as 7 weeks to limit unwanted reproduction. This surgery also prevents undesirable sex-related behavior, such as aggression, territory marking (spraying urine) in males and yowling (calling) in females. Traditionally, this surgery was performed at around six to nine months of age, but it is increasingly being performed prior to puberty, at about three to six months. In the USA approximately 80% of household cats are neutered.


vocalizations


The cat is a very vocal animal. Known for its trademark purring, it also produces a wide variety of other sounds.


The mechanism by which cats purr is elusive. The cat has no unique anatomical feature that is clearly responsible for the sound. It was, until recent times, believed that only the cats of the Felis genus could purr. However, felids of the Panthera genus (tiger, lion, jaguar and leopard) also produce sounds similar to purring, but only when exhaling.


ecology


habitats


Cats are a cosmopolitan species and are found across much of the world. They are extremely adaptable and are now present on all continents except Antarctica, and on 118 of the 131 main groups of islands – even on sub-Antarctic islands such as the Kerguelen Islands. Feral cats can live in forests, grasslands, tundra, coastal areas, agricultural land, scrublands, urban areas and wetlands. Their habitats even include small oceanic islands with no human inhabitants. This ability to thrive in almost any terrestrial habitat has led to the cat's designation as one of the world's worst invasive species. Despite this general adaptability, the close relatives of domestic cats, the African Wildcat (Felis silvestris lybica) and the Arabian Sand Cat (Felis margarita) both inhabit desert environments, and domestic cats still show similar adaptations and behaviors.


impact on prey species


To date, there are few scientific data available to assess the impact of cat predation on prey populations. Even well-fed domestic cats may hunt and kill, mainly catching small mammals, but also birds, amphibians, reptiles, fish and invertebrates. Hunting by domestic cats may be contributing to the decline in the numbers of birds in urban areas, although the importance of this effect remains controversial. In the wild, the introduction of feral cats during human settlement can threaten native species with extinction. In many cases controlling or eliminating the populations of non-native cats can produce a rapid recovery in native animals. However, the ecological role of introduced cats can be more complicated: for example, cats can control the numbers of rats, which also prey on birds' eggs and young, so in some cases eliminating a cat population can actually accelerate the decline of an endangered bird species in the presence of a mesopredator, controlled by cats.


In the Southern Hemisphere, cats are a particular problem in landmasses such as Australasia, where cat species have never been native and there were few equivalent native medium-sized mammalian predators. Native species such as the New Zealand Kakapo and the Australian Bettong, for example, tend to be more ecologically vulnerable and behaviorally "naive" to predation by feral cats. Feral cats have had a major impact on these native species and have played a leading role in the endangerment and extinction of many animals.


Cat numbers in the UK are growing annually and their abundance is far above the "natural" carrying capacity, because their population sizes are independent of their prey's dynamics: i.e. cats are "recreational" hunters, with other food sources. Population densities can be as high as 2,000 individuals per km2 and the current trend is an increase of 0.5 million cats annually.


impact on birds


The domestic cat is probably a significant predator of birds. Current UK assessments indicate that they may be accountable for an estimated 64.8 million bird deaths each year. Certain species appear more susceptible than others; for example, 30% of house sparrow mortality is linked to the domestic cat. In the recovery of ringed robins (Erithacus rubecula) and dunnocks (Prunella modularis), it was also concluded that 31% of deaths were a result of cat predation. The presence of larger carnivores such as coyotes which prey on cats and other small predators reduces the effect of predation by cats and other small predators such as opossums and raccoons on bird numbers and variety. The proposal that cat populations will increase when the numbers of these top predators decline is called the mesopredator release hypothesis.


On islands, birds can contribute as much as 60% of a cat's diet. In nearly all cases, however, the cat cannot be identified as the sole cause for reducing the numbers of island birds, and in some instances eradication of cats has caused a ‘mesopredator release’ effect; where the suppression of top carnivores creates an abundance of smaller predators that cause a severe decline in their shared prey. Domestic cats are, however, known to be a contributing factor to the decline of many species; a factor that has ultimately led, in some cases, to extinction. The South Island Piopio, Chatham Islands Rail, the Auckland Islands Merganser, and the common diving petrel are a few from a long list, with the most extreme case being the flightless Stephens Island Wren, which was driven to extinction only a few years after its discovery.


Some of the same factors that have promoted adaptive radiation of island avifauna over evolutionary time appear to promote vulnerability to non-native species in modern time. The susceptibility inherent of many island birds is undoubtedly due to evolution in the absence of mainland predators, competitors, diseases and parasites. In addition to lower reproductive rates and extended incubation periods. The loss of flight, or reduced flying ability is also characteristic of many island endemics. These biological aspects have increased vulnerability to extinction in the presence of introduced species, such as the domestic cat. Equally, behavioural traits exhibited by island species, such as "predatory naivety" and ground-nesting, have also contributed to their susceptibility.


cats and humans


Cats are a common companion animal in Europe and North America, and their worldwide population exceeds 500 million. Although cat ownership has commonly been associated with women, a 2007 Gallup poll reported that men and women were equally likely to own a cat.


According to the Humane Society of the United States, as well as being kept as pets, cats are also used in the international fur trade, for making coats, gloves, hats, shoes, blankets and stuffed toys. About 24 cats are needed to make a cat fur coat. This use has now been outlawed in several countries, including the United States, Australia and the European Union. However, some cat furs are still made into blankets in Switzerland as folk remedies that are believed to help rheumatism.


People less often eat cat meat than the flesh of other common domestic animals.


feral cats


Feral cats are domestic cats that were born in or have reverted to a wild state. They are unfamiliar with and wary of humans and roam freely in urban and rural areas.The numbers of feral cats are not known, but estimates of the US feral population range from 25 to 60 million. Feral cats may live alone, but most are found in large groups called feral colonies, which occupy a specific territory and are usually associated with a source of food. Famous feral cat colonies are found in Rome around the Colosseum and Forum Romanum, with cats at some of these sites being fed and given medical attention by volunteers.


Public attitudes towards feral cats vary widely: ranging from seeing them as free-ranging pets, to regarding them as vermin. One common approach to reducing the feral cat population is termed trap-neuter-return, where the cats are trapped, neutered, immunized against rabies and the feline leukemia virus, and then released. Before releasing them back into their feral colonies, the attending veterinarian often nips the tip off one ear to mark the feral as neutered and inoculated, since these cats may be trapped again. Volunteers continue to feed and give care to these cats throughout their lives. Given this support, their lifespan is increased, and behavior and nuisance problems caused by competition for food are reduced.


history and mythology


Traditionally, historians tended to think that ancient Egypt was the site of cat domestication, owing to the clear depictions of house cats in Egyptian paintings about 3,600 years old. However, in 2004, a Neolithic grave was excavated in Shillourokambos, Cyprus, that contained the skeletons, laid close to one another, of both a human and a cat. The grave is estimated to be 9,500 years old, pushing back the earliest known feline–human association significantly. The cat specimen is large and closely resembles the African wildcat (Felis silvestris lybica), rather than present-day domestic cats. This discovery, combined with genetic studies, suggest that cats were probably domesticated in the Middle East, in the Fertile Crescent around the time of the development of agriculture and then they were brought to Cyprus and Egypt.


In ancient Egypt cats were sacred animals, with the goddess Bastet often depicted in cat form, sometimes taking on the warlike aspect of a lioness. The Romans are often credited with introducing the domestic cat from Egypt to Europe; in Roman Aquitaine, a 1st or 2nd century epitaph of a young girl holding a cat is one of two earliest depictions of the Roman domesticated cat. However, it is possible that cats were already kept in Europe prior to the Roman Empire, as they may have already been present in Britain in the late Iron Age. Domestic cats were spread throughout much of the rest of the world during the Age of Discovery, as they were carried on sailing ships to control shipboard rodents and as good-luck charms.


Several ancient religions believed that cats are exalted souls, companions or guides for humans, that they are all-knowing but are mute so they cannot influence decisions made by humans. In Japan, the maneki neko is a cat that is a symbol of good fortune. Although there are no sacred species in Islam, some writers have stated that Muhammad had a favorite cat, Muezza. He is reported to have loved cats so much that "he would do without his cloak rather than disturb one that was sleeping on it".


Freyja—the goddess of love, beauty, and fertility in Norse mythology—is depicted as riding a chariot drawn by cats.


Many cultures have negative superstitions about cats. An example would be the belief that a black cat "crossing your path" leads to bad luck, or that cats are witches' familiars used to augment a witch's powers and skills. The killing of cats in Medieval Ypres is commemorated in the innocuous present-day Kattenstoet (cat parade).


According to a myth in many cultures, cats have multiple lives. In many countries, they are believed to have nine lives, but in Germany and some Spanish-speaking regions they are said to have seven lives, while in Turkish and Arabic traditions the number of lives is six. The myth is attributed to the natural suppleness and swiftness cats exhibit to escape life-threatening situations. Also lending credence to this myth is the fact that falling cats often land on their feet, using an instinctive righting reflex to twist their bodies around. Nonetheless, cats can still be injured or killed by a high fall.
