I've noticed that Lou put on some weight so I cut back a lot on his mealworms, but haven't really noticed a difference. He has a CSW and does use it during the night (he's in my room, so I know), but not nearly like he used to. Any ideas to why he runs less? He doesn't have any toys, but if someone has any suggestions, I'm all ears! I am moving (tomorrow in fact) and will have a much bigger room so Lou will be getting a cage upgrade (C&C 3x2)! Do you think this will help him be a little more active? He's by no means overweight, but I don't want it to get any worse.
