The cat (Felis catus) is a domestic species of small
carnivorous mammal. It is the only domesticated species in the family
Felidae and is commonly referred to as the domestic cat or
house cat to distinguish it from the wild members of the family.
Cats are commonly kept as house pets but can also be farm cats or feral
cats; the feral cat ranges freely and avoids human contact. Domestic
cats are valued by humans for companionship and their ability to kill
rodents. About 60 cat breeds are recognized by various cat registries.
