Many pedigreed and especially purebred cats are exhibited as show cats.Cats of unrecorded, mixed ancestry are referred to as domestic short-haired or domestic 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.and include lions, tigers, cougars and many others. Two main theories are given about how cats were domesticated.Within this family, domestic cats (Felis catus) are part of the genus Felis, which is a group of small cats containing about seven species (depending upon classification scheme). In one, people deliberately tamed cats in a process of artificial selection as they were useful predators of vermin.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.Cats, despite being solitary hunters, are a social species and cat communication includes the use of a variety of vocalizations (mewing, purring, trilling, hissing, growling, and grunting), as well as cat pheromones and types of cat-specific body language.
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.Cats are thought to be primarily responsible for the extinction of 33 species of birds, and the presence of feral and free-ranging cats makes some otherwise suitable locations unsuitable for attempted species reintroduction. In comparison to dogs, cats have not undergone major changes during the domestication process, as the form and behavior of the domestic cat is not radically different from those of wildcats and domestic cats are perfectly capable of surviving in the wild.A 2016 study found that leopard cats were undergoing domestication independently in China around 5,500 BC, though this line of partially domesticated cats leaves no trace in the domesticated populations of today. Cats have either a mutualistic or commensal relationship with humans.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 neutering, as well as the abandonment of former household pets, has resulted in large numbers of feral cats worldwide, requiring population control.Huehnergard opines it is "equally likely that the forms might derive from an ancient Germanic word, imported into Latin and thence to Greek and to Syriac and Arabic".
