20 cats, 10 she-cats and 10 toms, are taken into the wilderness, and split into two tribes. They must figure out how to survive in strange environments, and hunt strange prey to survive. Each week the two tribes will compete in a challenge, and the winning team will win immunity from the nominations. When only 10 cats remain, they will join together as one tribe, and the chalenges will turn from being team challenges to being individual challenges, and the cat who wins gets immunity from nominations that week. The one cat that remains is the winner.
