Not the AC that posted that but I would guess it's because hamsters are bigger than fish. Guinea pigs are bigger than hamsters, rabbits are bigger than Guinea pigs, cats are bigger than rabbits, dogs are bigger than cats, wolves are bigger than dogs, walrus's are bigger than wolves and walrus's can fish. Therefore fish are greater than pets once the circle is complete.
