I decided to give my boy an early Christmas present today and return his favorite basking spot, his bonsai tree. I had taken it away in October because he was trying to brumate after a couple of chilly nights and he's just way too young for that ( 4 months now, 2 then). It sure fits a lot better in the bigger habitat, and I doubt I'll have the hiding issues, as he's twice as big now as he was when I took it away and won't be able to get inside.
