What I meant was that I can't do a full room heater constantly. He still has an adequate UTH. 75 degrees is new information to me. Every other source that I've seen has said around 70-75 which is what my cold side is. I think I've figured out what the problem is though. For some reason he really likes this half log but I took it out a while ago to give him a little more room. Within 10 minutes of putting it back in he stopped all weird behavior and fell alseep in his hide.
