She's got 2 bunnys she keeps in jail in our rec room. If she keeps the cage clean (not likely), they don't stink too bad. if she lets it go a coupla days the ammonia smell is purty strong. They're fuggin noisy at night, banging their dishes around. They do nip occasionally, but I don't think they've ever actually bitten. They chew through just about anything, so computer, sterio, and TV wires are endangered.
