My male Pastel eats like a horse, and is rather fat atm. Gonna take him off two rat fuzzies and give him one every two weeks until he slims down, but he's shedding his skin and has managed to shed it on his body except for his head. upper body and eyes, he doesn't appear to be trying to rub it off, and I've soaked him and soaked him in warm water. What else can I do? The skin just isn't wanting to peel, I can't even try and rub it off with a towel after soaking.
