Oh man, too many to state. But if I were to give my top few, in no particular order: Rabbit/Hare, Were (like werewolf and other species versions), T-rex feet/paws (and other similar dino feet/paws), dragon paws. But as for footwear, I prefer to be inside of them under the sole for the foot/paw, rather than under the footwear itself. But being under socked paws is nice for cozy warm reasons. :3
