Gallifreyan cat

Gallifreyan cats were cats from the planet Gallifrey. (NA: Human Nature) Their relationship, if any, to Earth cats was unclear. They were likely not native to the Time Lord homeworld, however. The Fifth Doctor once told Tegan that his first incarnation and a Time Lord contemporary known as Ruath "introduced cats into Gallifrey's ecosystem", but he did not indicate where the cats had originated. (MA: Goth Opera) At some later date, one of the Presidents of Gallifrey had a pet cat. It was eaten by a mouse that had been enlarged by the Rani in an experiment. (DW: The Mark of the Rani)
