I'd say it looks fine. he deosn't seem to be that old, and for a young one thats not bad at all. How long have you had him? Do you know how old he is/ And is he eating good for you and regularly?
He hasn't eaten for 4 days I'm going to try again today. The pic I took is when I just got him. He doesn't look that much different now. About the same size and he's pooping normally so I'm not too worried.
