I got a normal BP about 2 weeks ago, been feeding mouse every 7 days, he has ate good both times, just feed him today he was on it within 5 seconds of putting the mouse in the box with him and had it down in like 8 min, he has been spending a lot of time on the cooler side lately.. even after he just ate he went to the cooler side right away, I currently have 2 different hides in the cage right now, the one on the warm side with the UTH is more open on the bottom so he can use the UTH better, the one on the cooler side is a bit smaller log structure that is a bit smaller then the one on the warm side. Temps are currently 88F on the hot side with 69% humidity(high right now due to substrate change) and 81F and 66% humidity on cooler side. I don't have a temp controller for the UTH so I keep the substrate about 3/4 to 1 inch think there.

Just wondering if he is avoiding the hot side because the hide might be too big?
