Hmmmm... Let's see, your character is a hunter, so... Yes, I suppose that's alright. Make a separate CS for it, similar to the Cat Squad CS's I have put up, and then I can add it in. One Grade B cat and three Grade A's, that will definitely make for some interesting social hierarchy in the feline world.

Other than that, no more cats. Cats are expensive, yo, this team ain't got the money for more than three cats, and no more space than for four. That rule, of course, doesn't apply to those Unknown, whom are welcome to have cats, dogs, whatever, so long as they keep in mind that only cats are completely immune to the Illness. Other animals have lower rates of immunity than humans, below 30%.
