Killer Cat of Gin-Seng

The Killer Cats of Gin-Seng were sapient felines from the Gin-Seng region of Gallifrey. (AUDIO: Erasure) The Second Doctor once mentioned mercenaries from Gin-Seng as being one of the Felinetta races. (PROSE: Invasion of the Cat-People) They hated the rituals of the Great Houses and had the ability of precognition. (PROSE: The Return of the King)

The Killer Cats once rose against the Time Lords (AUDIO: Erasure) in the Crisis of Gin-Seng, (AUDIO: The Last Fairy Tale) which was stopped by the Fourth Doctor. The Celestial Intervention Agency erased all records of this incident, a cover-up that Narvin believed benefited not just the Time Lords but everyone who lived on Gallifrey. (AUDIO: Erasure)

By the beginning of the Imperator's rule, the Cats were vanishing from the Homeworld to escape the coming War in Heaven. Thessalia's oracle was one of the few remaining Cat People. (PROSE: The Return of the King) The boy who would grow up to become Lord Yellow Dog of the Thirty-One Cuts told Larissa that during his nighttime explorations he once journeyed to caverns beneath House Ixion and saw meetings of wild things who hid sharp teeth and claws in their dark robes. (PROSE: Newtons Sleep)
