If he ate he needs to be on heat to digest his meal. If the feeding box has a hot spot around 90 it would be ok give him his water bowl also. if not hook him and use your other hand to also grab him, don't want to pull too much with the hook being he just ate. when you hook him should change his mood out of feeding. you can also use the hook to keep his head away from your hand. if you don't have a hook. throw a towel over him before grabbing him. this is a method used to remove a hisses mother from her eggs.
