Ok I have a 33 inch ball python and we have been for awhile feeding him to large mice because a small rat was too big for him to get down easily. Well since he has grown we have started feeding one small rat as it is now easier for him. After he eats the rat he still stays open in his cage wandering around acting like he is looking for another mouse to eat. Is this just because he is used to being fed two or is he still hungry??? Should I also get a small mouse to fed his as well or do you think the one small rat is enough???
