The heating pad underneath one of the hides is literally barely warm, right now i'm getting only 87.5 reading there with my reptile thermometer. When I first purchased the heating pad, I actually went to return it because I figured it was defective because of the unimpressive amount of heat it produces, but turns out that's how it was supposed to work. My snake spends a lot of time under there and his skin looks super healthy. He has a 2nd hide with no heating underneath and he spends time there as well. Is there still cause for concern? And if so, how likely is it the reason he's not eating?
