Overview

The domestic cat (Felis catus) is a small carnivorous mammal in the family Felidae, commonly kept by people around the world. Often called a house cat when living indoors, the species has been associated with humans for millennia and exists in many forms: companion animals, working farm cats and populations that live independently of people. Domestic cats are one branch of the larger group of felids that also includes many wild species.

Physical characteristics and behaviour

Cats are typically small, agile predators with sharp retractable claws, acute night vision and sensitive hearing. Their diet is primarily meat, and they display hunting behaviours even when well fed. Typical descriptors include:

  • Body: lithe and flexible, enabling climbing and jumping.
  • Senses: excellent low-light vision, strong olfaction and hearing tuned to detect small prey.
  • Social behaviour: ranges from solitary to loosely social; many individuals form bonds with people and other animals.
  • Life stages and terminology: young cats are called kittens; intact females are often called queens and intact males toms.

Domestication and history

Evidence indicates that cats began living close to human settlements roughly several thousand years ago, drawn to grains and the rodents that fed on them. Over time this association became mutually beneficial: cats reduced pest numbers and humans tolerated and eventually bred them. The relationship between cats and humans developed differently from that of dogs, with a more independent domestic pattern that retained many wild-type behaviours.

Roles, uses and human relationships

Cats serve multiple roles today. Many are kept primarily as companions and household pets (pets), valued for company and emotional support. Others act as working animals: farm or barn cats help control rodent populations on farms. Where domestic animals adapt to living without regular human care, they form feral populations that can impact local wildlife and ecosystems.

Breeds, varieties and classification

There are many recognized cat breeds, plus numerous mixed or unpedigreed cats. Cats are often described by coat length—shorthair, longhair or hairless—or grouped as "domestic shorthair" and "domestic longhair" when not of a specific pedigree. Breed standards emphasize features such as coat pattern, body shape and temperament, but mixed-breed cats are common and diverse.

Wild relatives and important distinctions

The term "cat" is also used for wild felids, which range from the small wildcats found across many regions to the large, charismatic species often called "big cats." Well-known examples of large wild felids include the lion, tiger, leopard, jaguar, puma and cheetah. Smaller wild species, such as the lynx, occur in parts of northern Europe and other regions. Wild felids tend to be less tolerant of people and may be dangerous; domestic cats generally lack the size and strength of those larger relatives.
