The '''cat''' ('''''Felis catus'''''), commonly referred to as the '''domestic cat''' or '''house cat''', is the only [[Domestication of animals|domesticated]] species in the family [[Felidae]]. Recent advances in [[archaeology]] and [[genetics]] have shown that the [[domestication of the cat]] occurred in the [[Near East]] around 7500 [[Before Christ|BC]]. It is commonly kept as a house pet and [[farm cat]], but also ranges freely as a [[feral cat]] avoiding human contact. It is valued by humans for companionship and its ability to kill [[vermin]]. Because of its retractable [[claw]]s it is adapted to killing small prey like [[mice]] and [[rat]]s. It has a strong flexible body, quick [[reflexes]], sharp teeth, and its [[night vision]] and [[sense of smell]] are well developed. It is a [[social species]], but a solitary hunter and a [[crepuscular]] [[predator]]. [[Cat communication]] includes vocalizations like [[meow]]ing, [[purr]]ing, trilling, hissing, [[growling]], and grunting as well as [[cat body language]]. It can hear sounds too faint or too high in [[frequency]] for human ears, such as those made by small mammals. It also secretes and perceives [[pheromones]].

Female domestic cats can have [[kittens]] from spring to late autumn in temperate zones and throughout the year in equatorial regions, with litter sizes often ranging from two to five kittens. Domestic cats are bred and shown at events as registered [[pedigreed cat]]s, a hobby known as [[cat fancy]]. [[Animal population control]] of cats may be achieved by [[spaying]] and [[neutering]], but their proliferation and the abandonment of pets has resulted in large numbers of feral cats worldwide, contributing to the extinction of [[bird]], [[mammal]] and [[reptile]] species.

{{As of|2017|post=,}} the domestic cat was the second most popular pet in the United States, with 95.6&nbsp;million cats owned and around 42 million households owning at least one cat. In the United Kingdom, 26% of adults have a cat, with an estimated population of 10.9&nbsp;million pet cats {{As of|2020|lc=y|post=.}} {{As of|2021|post=,}} there were an estimated 220 million owned and 480&nbsp;million stray cats in the world.

==Etymology and naming==
The origin of the English word ''cat'', [[Old English]] {{lang|ang|catt}}, is thought to be the [[Late Latin]] word {{lang|la|cattus}}, which was first used at the beginning of the 6th century.<ref>{{Cite book |last=McKnight |first=G.

The English ''[[wikt:puss#English|puss]]'', extended as ''pussy'' and ''pussycat'', is attested from the 16th century and may have been introduced from [[Dutch language|Dutch]] {{lang|nl|poes}} or from [[Low German]] {{lang|nds|puuskatte}}, related to [[Swedish language|Swedish]] {{lang|sv|kattepus}}, or [[Norwegian language|Norwegian]] {{lang|no|pus}}, {{lang|no|pusekatt}}.

Most cats have five claws on their front paws and four on their rear paws. The [[dewclaw]] is [[proximal]] to the other claws. More proximally is a protrusion which appears to be a sixth "finger".

Cats are generally fond of sitting in high places or ''perching''. A higher place may serve as a concealed site from which to hunt; domestic cats strike prey by pouncing from a perch such as a tree branch. Another possible explanation is that height gives the cat a better observation point, allowing it to survey its territory.

===Whiskers===

Cats conserve energy by sleeping more than most animals, especially as they grow older. The daily duration of sleep varies, usually between 12 and 16 hours, with 13 and 14 being the average. Some cats can sleep as much as 20 hours. 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 they are dreaming.<ref>{{Cite journal |doi=10.1016/0166-2236(79)90110-3 |volume=2 |pages=280–282 |last=Jouvet |first=M. |title=What Does a Cat Dream About? |journal=Trends in Neurosciences |date=1979|s2cid=53161799}}</ref>

[[Redirected aggression]] is a common form of aggression which can occur in multiple cat households. In redirected aggression there is usually something that agitates the cat: this could be a sight, sound, or another source of stimuli which causes a heightened level of anxiety or arousal. If the cat cannot attack the stimuli, it may direct anger elsewhere by attacking or directing aggression to the nearest cat, dog, human or other being.<ref name="Horwitz">{{cite news |last1=Horwitz |first1=Debra |title=Cat Behavior Problems - Aggression Redirected |url= https://vcahospitals.com/know-your-pet/cat-behavior-problems-aggression-redirected#:~:text=What%20is%20redirected%20aggression%3F,cat%20out%20on%20the%20property |access-date=16 June 2022 |publisher=VCA Animal Hospitals |date=2022 |archive-date=19 March 2022 |archive-url=https://web.archive.org/web/20220319184510/https://vcahospitals.com/know-your-pet/cat-behavior-problems-aggression-redirected#:~:text=What%20is%20redirected%20aggression%3F,cat%20out%20on%20the%20property |url-status=live}}</ref><ref name="Behaviorist">{{cite news |last1=Johnson |first1=Ingrid |title=Redirected Aggression in Cats: Recognition and Treatment Strategies |url= https://iaabc.org/cat/redirected-aggression-in-cats |access-date=16 June 2022 |publisher=International Association of Animal Behavior Consultants |date=17 May 2014 |archive-date=7 March 2022 |archive-url= https://web.archive.org/web/20220307001045/https://iaabc.org/cat/redirected-aggression-in-cats |url-status=live}}</ref>

The exact mechanism by which cats purr has long been elusive, but it has been proposed that purring is generated via a series of sudden build-ups and releases of pressure as the [[glottis]] is opened and closed, which causes the [[vocal folds]] to separate forcefully. The laryngeal muscles in control of the glottis are thought to be driven by a [[neural oscillation|neural oscillator]] which generates a cycle of contraction and release every 30–40 [[millisecond]]s (giving a frequency of 33 to 25&nbsp;Hz).<ref name="bradshaw2012">{{cite book |last=Bradshaw |first=John W.

Cats may also vocalize loudly and bare their teeth in an effort to further intimidate their opponents.

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. Fights for mating rights are typically more severe and injuries may include deep puncture wounds and lacerations. Normally, serious injuries from fighting are limited to infections of scratches and bites, though these can occasionally kill cats if untreated.

The shape and structure of cats' cheeks is insufficient to allow them to take in liquids using suction. Therefore, when drinking they lap with the tongue to draw liquid upward into their mouths.

Feral cats and free-fed house cats consume several small meals in a day. The frequency and size of meals varies between individuals. They select food based on its temperature, smell and texture; they dislike chilled foods and respond most strongly to moist foods rich in amino acids, which are similar to meat.

Perhaps the best-known element of cats' hunting behavior, which is commonly misunderstood and often appalls cat owners because it looks like torture, is that cats often appear to "play" with prey by releasing and recapturing it. This [[cat and mouse]] behavior is due to an instinctive imperative to ensure that the prey is weak enough to be killed without endangering the cat.<ref>{{cite news |title=Why do cats play with their food? |url= http://azdailysun.com/lifestyles/pets/article_46a97775-232d-5e56-b0ea-dd1c8782b062.html |newspaper=Arizona Daily Sun |access-date=15 August 2011 |url-status=live |archive-url= https://web.archive.org/web/20110319041928/http://www.azdailysun.com/lifestyles/pets/article_46a97775-232d-5e56-b0ea-dd1c8782b062.html |archive-date=19 March 2011}}</ref>

Another poorly understood element of cat hunting behavior is the presentation of prey to human guardians. One explanation is that cats adopt humans into their social group and share excess kill with others in the group according to the [[dominance hierarchy]], in which humans are reacted to as if they are at or near the top.<ref name="Leyhausen 1978">{{cite book |title=Cat Behavior: The predatory and social behavior of domestic and wild cats |last=Leyhausen |first=P. |date=1978 |publisher=[[Garland STPM Press]] |location=New York |isbn=9780824070175}}</ref> Another explanation is that they attempt to teach their guardians to hunt or to help their human as if feeding "an elderly cat, or an inept kitten".<ref name="Morris Catwatching 1">{{cite book |title=Catwatching: Why cats purr and everything else you ever wanted to know |last=Desmond |first=M. |date=2002 |publisher=Ebury Press |edition=2nd |location=London |chapter=Why does a cat play with its prey before killing it? |pages=51–52 |isbn=9781409022213 |chapter-url= https://books.google.com/books?id=Q3ysT6xTJu4C&pg=PA51 |access-date=25 October 2020 |archive-date=31 March 2021 |archive-url= https://web.archive.org/web/20210331062240/https://books.google.com/books?id=Q3ysT6xTJu4C&pg=PA51 |url-status=live}}</ref> This hypothesis is inconsistent with the fact that male cats also bring home prey, despite males having negligible involvement in raising kittens.<ref name="Turner 2000" />{{rp|153}}

Several males, called tomcats, are attracted to a female in heat. They fight over her, and the victor wins the right to mate. At first, the female rejects the male, but eventually, the female allows the male to mate.

The unwantedness that leads to the domestic cat being [[Cat predation on wildlife#Impact by location|treated as an invasive species]] is twofold.

===History and mythology===
{{Main|Cultural depictions of cats|Cats in ancient Egypt}}
In [[ancient Egypt]], cats were [[animal worship|revered]], and the goddess [[Bastet]] often depicted in cat form, sometimes taking on the war-like aspect of a lioness. The Greek historian [[Herodotus]] reported that killing a cat was forbidden, and when a household cat died, the entire family mourned and shaved their eyebrows. Families took their dead cats to the sacred city of [[Bubastis]], where they were embalmed and buried in sacred repositories. Herodotus expressed astonishment at the domestic cats in Egypt, because he had only ever seen wildcats.<ref name="Malek1997">{{cite book |title=The Cat in Ancient Egypt |last=Malek |first=J. |date=1997 |publisher=University of Pennsylvania Press |isbn=9780812216325 |edition=Revised}}</ref>

Ancient Greeks and Romans kept [[weasel]]s as pets, which were seen as the ideal rodent-killers. The earliest unmistakable evidence of the Greeks having domestic cats comes from two coins from [[Magna Graecia]] dating to the mid-fifth century BC showing Iokastos and Phalanthos, the legendary founders of [[Reggio Calabria|Rhegion]] and [[Taranto|Taras]] respectively, playing with their pet cats. The usual ancient Greek word for 'cat' was {{lang|grc-Latn|ailouros}}, meaning 'thing with the waving tail'. Cats are rarely mentioned in [[ancient Greek literature]]. [[Aristotle]] remarked in his ''[[History of Animals]]'' that "female cats are naturally [[Promiscuity|lecherous]]." The Greeks later [[Interpretatio graeca|syncretized]] their own goddess [[Artemis]] with the Egyptian goddess Bastet, adopting Bastet's associations with cats and ascribing them to Artemis. In [[Ovid]]'s ''[[Metamorphoses]]'', when the deities flee to Egypt and take animal forms, the goddess [[Diana (mythology)|Diana]] turns into a cat.<ref name="Engels2001">{{Cite book |last=Engels |first=D.

Cats eventually displaced [[weasel]]s as the pest control of choice because they were more pleasant to have around the house and were more enthusiastic hunters of mice. During the [[Middle Ages]], many of Artemis's associations with cats were grafted onto the [[Mary, mother of Jesus|Virgin Mary]]. Cats are often shown in icons of [[Annunciation]] and of the [[Holy Family]] and, according to [[Folklore of Italy|Italian folklore]], on the same night that Mary gave birth to [[Jesus]], a cat in [[Bethlehem]] gave birth to a kitten.<ref name="Beadle1977">{{Cite book |last=Beadle |first=M. |title=Cat |date=1977 |publisher=[[Simon & Schuster]] |location=New York |isbn=9780671224516 |chapter=Ups and Downs |pages=[https://archive.org/details/cathistorybiolog00bead/page/75 75–88] |chapter-url= https://books.google.com/books?id=tnjgqpNKYksC&pg=PA75 |url= https://archive.org/details/cathistorybiolog00bead/page/75}}</ref> Domestic cats were spread throughout much of the rest of the world during the [[Age of Discovery]], as [[Ship's cat|ships' cats]] were carried on [[sailing ship]]s to control shipboard rodents and as good-luck charms.<ref name="Faure2009" />

Several ancient religions believed cats are exalted souls, companions or guides for humans, that are all-knowing but mute so they cannot influence decisions made by humans.

===Superstitions and rituals===
Many cultures have negative [[superstition]]s about cats. An example would be the belief that encountering a [[black cat]] ("crossing one's path") leads to bad luck, or that cats are witches' [[familiar spirit|familiars]] used to augment a witch's powers and skills. The killing of cats in Medieval [[Ypres]], [[Belgium]], is commemorated in the innocuous present-day [[Kattenstoet]] (cat parade).<ref>{{cite web |title=Are Black Cats Really Bad Luck?

According to a myth in many cultures, cats have multiple lives. In many countries, they are believed to have nine lives, but in Italy, Germany, Greece, Brazil and some Spanish-speaking regions, they are said to have seven lives,<ref>{{Cite news |title=Las vidas del gato |date=2010 |url= http://elcomercio.pe/impresa/notas/vidas-gato/20100307/423959 |access-date=19 March 2010 |first=N. |last=Sugobono |language=es |work=[[El Comercio (Peru)]] |location=Lima, Peru |url-status=dead |archive-date=27 January 2012 |archive-url= https://web.archive.org/web/20120127052854/http://elcomercio.pe/impresa/notas/vidas-gato/20100307/423959}}</ref><ref>{{cite web |title=Qual é a origem da lenda de que os gatos teriam sete vidas? |language=pt-BR |work=[[Mundo Estranho]] |publisher=[[Abril Media]] |location=São Paulo, Brazil |access-date=15 November 2015 |url= http://mundoestranho.abril.com.br/materia/qual-e-a-origem-da-lenda-de-que-os-gatos-teriam-sete-vidas |url-status=live |archive-url= https://web.archive.org/web/20151117031757/http://mundoestranho.abril.com.br/materia/qual-e-a-origem-da-lenda-de-que-os-gatos-teriam-sete-vidas |archive-date=17 November 2015}}</ref> while in Arabic traditions, the number of lives is six.<ref>{{Cite news |work=[[The Guardian]] |url= https://www.theguardian.com/lifeandstyle/gallery/2010/mar/18/guide-to-pets-pet-myths?picture=360591960 |access-date=November 15, 2023 |first=T. |last=Dowling |title=Tall tails: Pet myths busted |date=19 March 2010 |url-status=live |archive-url= https://web.archive.org/web/20130909160834/http://www.theguardian.com/lifeandstyle/gallery/2010/mar/18/guide-to-pets-pet-myths?picture=360591960|archive-date=9 September 2013}}</ref> An early mention of the myth can be found in [[John Heywood]]'s ''The Proverbs of John Heywood'' (1546):<ref>{{cite book |first=J- |last=Heywood |author-link=John Heywood |editor-first=Julian |editor-last=Sharman |url= https://archive.org/details/proverbsofjohnhe00heywrich/page/104/mode/2up |title=The Proverbs of John Heywood |date=1874 |page=104}}</ref>
{{Poem quote|text=Husband, ([[:wikt:quoth#Verb 2|quoth]] she), ye studie, be merrie now,

The myth is attributed to the natural suppleness and swiftness cats exhibit to escape life-threatening situations.<ref>{{cite web |title=Can Cats Cheat Death? |url= https://be.chewy.com/behavior-pet-facts-do-cats-really-have-nine-lives/ |website=BeChewy |date=6 October 2017 |access-date=25 September 2023}}</ref> Also lending credence to this myth is the fact that falling cats often land on their feet, using an instinctive [[cat righting reflex|righting reflex]] to twist their bodies around.
