My black cat, Moses is good for a few things. Some one in our area lets rabbits loose in our yard. Moses catches the rabbit and eats almost all of it. He also catches mice and small birds like starlings. He does not eat the starlings very often but my other grey cat will eat anything left behind by Moses. The grey cat has not caught its own food since we got it. Moses also tolerates toddler affection amazingly well. Over all I like Moses my black cat but the grey cat is pretty much useless.
