A pet that lives in your factory. It follows you, settles when you stop, fetches a thrown ball, warns you of biters, learns tricks and keeps a journal of everywhere you have been together. Pick your kitten's coat from 14 and name it; 12 species and 65 coats in all are found, rescued or bred. Build a kennel, whistle it to heel, feed it, and raise it over 90 hours. It can never be lost. Space Age optional.

Built for playing with family or friends on separate forces/teams.
