I've had my ball python for almost 2 years now and have had very few problems with him. However after his last feed he has been acting very oddly. I fed him 3 mice as opposed to his usual 1 or 2 to see if he'd take it, and he did happily. He shed quite soon after and pooped, all normal. However ever since he has been very inactive. He stays in his hide at all times unless I remove him for cleaning or handling. This is quite unusual as normally after he poops he is very active again almost immediately. I can't see any signs of impaction, or anything else wrong with him other than the lack of energy. Any advice would be greatly appreciated.
