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.
Feral cats are associated with human habitation areas and may be fed by people or forage for food, but are typically wary of human interaction.
Cats have seven cervical vertebrae, as do almost all mammals; 13 thoracic vertebrae (humans have 12); seven lumbar vertebrae (humans have five); three sacral vertebrae like most mammals (humans have five); and a variable number of caudal vertebrae in the tail (humans retain three to five caudal vertebrae, fused into an internal coccyx).
Cat senses fit a crepuscular and predatory ecological niche.
Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small animals. Like most other mammals, cats have poorer color vision and a better sense of smell than humans.
The origin of the English word cat (Old English catt) and its counterparts in other Germanic languages (such as German Katze), descended from Proto-Germanic *kattōn-, is controversial.
It has traditionally thought to be a borrowing from Late Latin cattus "domestic cat", from catta (used around 75 AD by Martial), The Late Latin word is generally thought to originate from an Afro-Asiatic language, but every proposed source word has presented problems.
A purebred cat is one whose ancestry contains only individuals of the same breed.Members of the genus are found worldwide and include the jungle cat (Felis chaus) of southeast Asia, European wildcat (F. This has been criticized as implausible, because the reward for such an effort may have been too little; 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.Failure to control the breeding of pet cats by neutering, as well as the abandonment of former household pets, has resulted in large numbers of feral cats worldwide, requiring population control.In certain areas outside cats' native range, this has contributed, along with habitat destruction and other factors, to the extinction of many bird species.
