I heat the cage with an UTH 24/7 on about 1/3 of the cage and if the ambient temperature starts getting low i turn on a red heat light. I have a thermostat connected to the UTH. I have a electric temperature gauge so i know the exact temp. But actually my BP is actually hiding now. I think it is because he was hungry. Like Neal said, i worried too much and overreacted. I was just getting nervous because he had lost over 10 grams in a week from his constant cruising, but he should gain it back now that he seems to be hiding and is getting larger meals. Thanks for your help!
