No that is nothing like a possum or raccoon the head to body size is all wrong for either of those and the feet front and back remain me of a type of monkey the way they lay and the toes. It isn't a monkey. It sure has a funny shape head, and it is very muscular. I wonder what it would look like in the face. The jaws are large, what you could see toward the nose isn't overly long either. I don't think it lost it hair, the skin looks alright. Keep it up there!
