Are you making your own Familiars in Cats and Dogs? Share!

one of my soon-to-be-witches already has a cat named Dieb (german for thief) and he's going to become her familiar, but he looks like a normal cat so no need to show him off here I guess, I love him though.
the other one has a cat too, Lucifer, but he's a grumpy old fella he would never go fetch or fight for his "owner", just not his cuppatea, so she is getting the evil bunny familiar.
