Cat
A cat was a type of predatory and typically small, feline mammal coming in a variety of colours, shapes and sizes. Cats could be found on a variety of planets, and were commonly domesticated as pets. (NA: Human Nature) At least some cats were capable of psychic communication with Time Lords, as the Doctor has spoken to several.
Cat variants
Earth cats
There were many species of cats found on Earth, including 'common' house cats, tigers and the sabre-toothed tigers. The cats of Earth went extinct some time before the year 2157 (NA: Lucifer Rising), with tigers dying out before 2148 (NA: St Anthony's Fire). The Tenth Doctor once claimed the cats on Earth weren't native to the planet but were in fact aliens, and rather than the rather prosaic names humans tend to give them, their actual names were much grander like "Great Hunter Grimalkin Greycoat Lionheart". Donna believed he was pulling her leg. (IDW: Autopia)
Gallifreyan cats
Cats could also be found on Gallifrey. (NA: Human Nature) One of the Presidents of Gallifrey had a pet cat. The cat was eaten by a mouse that had been enlarged by the Rani during an experiment. (DW: The Mark of the Rani)
Cheetah World's cats
The kitlings and the Cheetah people were two species of cat-like creatures found on the Cheetah World. Both were known to travel off-world. While visiting Earth, the kitlings were easily mistaken for terrestrial cats. (DW: Survival)
Anubian cats
A species called the Glomb, which was identical to a cat, was native to Anubis. (K9TV: Curse of Anubis)
Sapient cats
Several sapient species were cat-like in appearance.
