I don't know much about this little one other then he was sitting all by himself on a shelf at one of my favorite stores, so I scooped him up and he has been keeping all of the other critters in my hutch company since.  He told me it was getting to crowded in there and it was getting on his nerves so it is time for him to occupy a new shelf.  I'm unsure who made him as he is not marked on his backside like the others I've seen.  He weighs 5.7oz and is 1 5/8" tall x 1 1/4" across the base.
