I've had my adult male ball python for several years now, and he recently moved with me from Pennsylvania, to Houston, TX. Since I've started my PhD program I haven't been able to spend nearly as much time with him, and he often seems to be bored. While he sleeps all day, in the evenings when I'm getting ready for bed he just paces in circles around his tank (29 gallon) and pushes at the lid. I feel horrible and try to let him out around the apartment as much as possible, but I don't always have time for that. What should I do? Does he need a bigger tank? Is there some stimulating activity for him? Could I redecorate his tank? Help!
