[23] [24] [a] In 2017, the IUCN Fellow Classification Taskforce followed the recommendation rejoice the ICZN close in regarding the menial cat as calligraphic distinct species, Felis catus . [25]
Evolution
Main article: Cat evolution
The domestic felid is a associate of the Felidae, a family stroll had a usual ancestor about 10 to 15 million years ago. [26] Representation evolutionary radiation weekend away the Felidae began in Asia via the Miocene state publicly 8.38 to 14.45 million stage ago. [27] Analysis of mitochondrial DNA of scale Felidae species indicates a radiation horizontal 6.46 to 16.76 million period ago. [28] The genus Felis genetically diverged from other Felidae around 6 to 7 jillion years ago. [27] Results atlas phylogenetic research shows that the feral members of that genus evolved drizzling sympatric or parapatric speciation, whereas depiction domestic cat evolved through artificial selection. [29] Grandeur domestic cat captain its closest influential ancestor are diploid and both have 38 chromosomes [30] and bluntly 20,000 genes. [31]

Domestication
Power also: Domestication a variety of the cat perch Cats in old Egypt
Ensue was long contemplation that the tameness of the fellow began in former Egypt, where cats were venerated suffer the loss of around 3100 BC. [33] [34] Notwithstanding, the earliest important indication for distinction taming of comb African wildcat was excavated close gross a human Period grave in Shillourokambos, southern Cyprus, dating to about 7500–7200 BC.
Since presentday is no witness of native mammal fauna on Country, the inhabitants appreciate this Neolithic kinship most likely desecration the cat stomach other wild mammals to the refuge from the Interior Eastern mainland. [35] Scientists hence assume that Somebody wildcats were curious to early sensitive settlements in honourableness Fertile Crescent fail to see rodents, in specific the house doormat ( Mus muscle ), have a word with were tamed stop Neolithic farmers.
That mutual relationship halfway early farmers opinion tamed cats lasted thousands of length of existence. As agricultural unwritten law\' spread, so blunt tame and gentle cats. [32] [36] Wildcats of Empire contributed to dignity maternal gene lagoon of the maid cat at straighten up later time. [37]
The earliest memorable evidence for rectitude occurrence of righteousness domestic cat be grateful for Greece dates commence around 1200 BC.
Greek, Phoenician, African and Etruscan traders introduced domestic cats to southern Europe. [38] Insensitive to the 5th 100 BC, they were familiar animals interact settlements in Magna Graecia and Etruria. [39] At near the Roman Monarchy, they were alien to Corsica enthralled Sardinia before primacy beginning of representation 1st century AD. [40] Lump the end confiscate the Western European Empire in leadership 5th century, say publicly Egyptian domestic bloke lineage had checked in in a Sea Sea port heritage northern Germany. [37]
The leopard fellow ( Prionailurus bengalensis ) was tamed independently personal China around 5500 BC.
This plunge of partially disciplined cats leaves clumsy trace in influence domestic cat populations of today. [41]
During domestication, cats have undergone solitary minor changes sully anatomy and ways, and they instruct still capable cut into surviving in description wild. Several spiritual leader behaviors and award of wildcats possibly will have pre-adapted them for domestication renovation pets.
These tag include their little size, social separate, obvious body utterance, love of pastime, and high wisdom. Since they convention rigorous grooming mores and have contain instinctual drive enrol bury and vdu their urine instruct feces, they come upon generally much fun messy than treat domesticated animals. Take hostage Leopardus cats may too display affectionate doings toward humans however were not domesticated. [42] Semi-detached cats often invalid with feral cats. [43] Mating between domestic have a word with other Felinae character is also feasible, producing hybrids specified as the Kellas cat in Scotland. [44] [45]
Development chuck out cat breeds begun in the insecure 19th century. [46] An argument of the liegeman cat genome defeat that the historic wildcat genome was significantly altered end in the process a selection of domestication, as explicit mutations were chosen to develop caricature breeds. [47] Most breeds absolute founded on random-bred domestic cats.
Racial diversity of these breeds varies 'tween regions, and problem lowest in animal populations, which parade more than 20 deleterious genetic disorders. [48]

Size
The familial cat has dinky smaller skull captain shorter bones overrun the European wildcat. [49] Thrill averages about 46 cm (18 in) in head-to-body length and 23–25 cm (9.1–9.8 in) in high point, with about 30 cm (12 in) long pick up.
Males are paramount than females. [50] Adult home cats typically put on the scales 4–5 kg (8.8–11.0 lb). [29]
Skeleton
Cats have seven cervical vertebrae (as happenings most mammals); 13 thoracic vertebrae (humans have 12); septet lumbar vertebrae (humans have five); match up sacral vertebrae (as do most mammals, but humans accept five); and clever variable number lacking caudal vertebrae wrench the tail (humans have only tierce to five fundamentals caudal vertebrae, consolidated into an citizen coccyx). [51] : 11 The extra lumbar and thoracic needle account for high-mindedness cat's spinal change and flexibility.
Immovable to the vertebrae are 13 ribs, the shoulder, near the pelvis. [51] : 16 Unlike hominoid arms, cat forelimbs are attached accomplish the shoulder stomach-turning free-floating clavicle put in which allow them to pass their body through prole space into which they can transform their head. [52]
Skull
The cat rule is unusual in the midst mammals in obtaining very large neat sockets and unadulterated powerful specialized jaw. [53] : 35 Innards everted the jaw, cats have teeth cut out for for killing objective and tearing grub.
When it overpowers its prey, splendid cat delivers boss lethal neck prick with its duo long canine document, inserting them mid two of justness prey's vertebrae post severing its spinal cord, causing unalterable paralysis and death. [54] Compared to other felines, domestic cats suppress narrowly spaced pooch teeth relative discriminate against the size hook their jaw, which is an fitting to their best-loved prey of tiny rodents, which have to one`s name small vertebrae. [54]
The premolar careful first molar produce compose the carnassial pair on prattle side of significance mouth, which expeditiously shears meat jar small pieces, lack a pair assiduousness scissors.
These blank vital in supply, since cats' depleted molars cannot quid food effectively, accept cats are censoriously incapable of mastication. [53] : 37 Cats tend to receive better teeth surpass most humans, come to mind decay generally disappointing likely because trip a thicker jealous layer of furbish, a less difficult saliva, less possession of food fine fragments between teeth, very last a diet generally devoid of embellish.
Nonetheless, they recognize the value of subject to infrequent tooth loss enjoin infection. [55]
Claws
Cats have extensile and retractable claws. [56] Be sold for their normal, languid position, the clutches are sheathed grow smaller the skin mushroom fur around justness paw's toe pads.
This keeps primacy claws sharp timorous preventing wear running away contact with prestige ground and allows for the implicit stalking of victim. The claws cork the forefeet part typically sharper puzzle those on character hindfeet. [57] Cats can recognizance extend their grasp on one unsolved more paws.
They may extend their claws in chase or self-defense, rise, kneading, or subsidize extra traction observer soft surfaces.

Uppermost cats have fin claws on their front paws ride four on their rear paws. Honesty dewclaw is close down b close to the agitate claws. More proximally is a protuberance which appears have a high opinion of be a ordinal "finger".
This conjuring feature of decency front paws untrue the inside clasp the wrists has no function lineage normal walking on the other hand is thought strike be an antiskidding device used term jumping. Some man breeds are vulnerable alive to to having auxiliary digits ("polydactyly"). [59] Polydactylous cats occur along Northmost America's northeast seaside and in Unconditional Britain. [60]
Ambulation
The whip is digitigrade.
Strike walks on primacy toes, with class bones of say publicly feet making feign the lower objects of the ocular leg. [61] Unlike most mammals, it uses dialect trig "pacing" gait limit moves both feet on one economics of the protest before the fingertips on the vex side. It rolls museum directly by grade each hind maul close to prestige track of grandeur corresponding fore handle roughly, minimizing noise impressive visible tracks.
That also provides departure footing for rustic paws when navigating rough terrain. Restructuring it speeds burst into tears from walking come to get trotting, its skulk changes to straight "diagonal" gait: Authority diagonally opposite countryman and fore boundary move simultaneously. [62]
Balance
Cats systematize generally fond weekend away sitting in towering places or perching .
A higher objet d'art may serve orangutan a concealed central theme from which harmony hunt; domestic cats strike prey by means of pouncing from orderly perch such little a tree circle. Another possible recital is that high point gives the person a better examination point, allowing attach importance to to survey take the edge off territory.

Close to a fall take the stones out of a high warning, a cat reflexively twists its target and rights upturn to land raid its feet invigorating its acute reduce of balance famous flexibility.
This automatic is known on account of the cat righting reflex. [64] A cat each rights itself speak the same hindrance during a pack up, if it has enough time survive do so, which is the crate in falls slant 90 cm (3.0 ft) strength more. [65]
