The domestic cat is a small, usually furry, domesticated, and carnivorous mammal. It is often called a housecat when kept as an indoor pet,[6] or simply a cat when there is no need to distinguish it from other felids and felines. Cats are often valued by humans for companionship, and their ability to hunt vermin and household pests.Cats are similar in anatomy to the other felids, with strong, flexible bodies, quick reflexes, sharp retractable claws, and teeth adapted to killing small prey.
