yesterday i changed my BP's substrate and just went about my day after i was done. well i noticed a few hours later that he still wasnt back in his hide box like he usually is. i didnt really think much of it until this morning. he was still just sitting out side his hide boxes. so i picked him up and he was really cold. so i held him and warmed him up a bit. and put him back down in his cage. when i put him down he literally made a B line for his hide on the hot side of his cage. is there a reason he would have stayed out all night. my temps are perfect and my humidity is reading 45% now. so i think im good there. if anyone has any suggestions, it would be much appreciated
