A Cat (Felis sylvestris catus or Felis domesticus) is a small animal native to Earth. A mammal, cats were domesticated by humans several thousand years ago, and since that time have been kept as pets by humans.
Sometimes called "housecats", that term fell out of use by the 23rd century, to avoid confusion with the Meridian housecat, a large animal that hosted smaller symbiotic organisms. (TOS novel: Prime Directive)
