Rodon (forefront) and his followers
The Feral Cats are the ruling faction of the nomadic Felis sapiens aboard the Cat Fleet and who originated aboard Red Dwarf.
The Feral Cats worship Rodon, the 'Feral King' as their deity and follow out his commands in executing any cats following the old cat religion and the old god Cloister, actually the last human Dave Lister. (The Promised Land)
