A cat, also known as Felis catus, (AUDIO: The Case of the Missing Gasogene) was a type of predatory and usually small feline mammal. Cats came in a variety of colours and shapes and were commonly domesticated as pets. (PROSE: Human Nature)

Originally biologically engineered by the pre-time travel Gallifreyans as the calculating animals with tails (of which phrase "cat" was an acronym), the Gallifreyan cat had then been seeded throughout the universe by the Gallifreyans as part of their effort to set themselves up as gods. Gallifreyan cats were intelligent, talking beings, though they still served as pets to their humanoid owners; (PROSE: The Legacy of Gallifrey) the Tenth Doctor once explained to Donna Noble that not only were the cats on Earth not native to the planet rather of alien origins, but that they too were intelligent beings. Rather than the prosaic names their human "owners" tended to give them, their actual names were much grander like "Great Hunter Grimalkin Greycoat Lionheart". Donna, however, did not believe him. (COMIC: Autopia) The cats that resided in Levenshulme corroborated this, as they all displayed intelligence comparable to that of a human, and they chose their names too, but they tended to be subtler. (PROSE: The Story of Fester Cat)

Cats on Earth were extinct by the year 2157. (PROSE: Lucifer Rising)

Maine Coons, Abyssinians, Persians, Manxes, (PROSE: Frayed) Siamese, (PROSE: Suitors, Inc.) and tortoiseshells were all types of cats. (PROSE: The Story of Fester Cat)
