The domestic cat (Felis catus or Felis silvestris catus) is a small, usually furry, domesticated, and carnivorous mammal. They are often called housecats when kept as an indoor pet or simply cats when there is no need to distinguish them from other felids and felines. Cats are often valued by humans for companionship and their ability to hunt 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. 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. They can see in near darkness. Like most other mammals, cats have poorer color vision and a bettersense of smell than humans.
Despite being solitary hunters, cats 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.
