Kitling

The kitlings resembled large black house cats with yellow eyes. The kitlings could teleport from planet to planet like the Cheetah People though it seems the kitlings did not have the Cheetah People's limitations as far as having to have a link with a planet in order to travel there.

They were scavengers that used their powers to find carrion on different planets. The Cheetah People could also telepathically control the kitlings and could see through their eyes. They used the kitlings to find new sources of food, while the kitlings fed off the scraps. The kitlings were bred by an unknown civilisation on the Cheetah People's planet for spying purposes, though that civilisation eventually collapsed.

They were used by the Master to teleport people (humans specifically) to the Cheetah World. So that he could get one of them infected turning them into a Cheetah person so that he could escape the rapidly deterioating Cheetah planet. (DW: Survival)
