I am pretty sure his temp is good. Around 90F hot spot and 75-80F cool side. These are the same temps he's been with his entire life and he's never had a problem with them before. I don't have a humidity reader in his cage but I mist it once or twice a day, depending on how hot it is outside, and get perfect sheds almost every time.
Now that I think about it, there have been tree cutters on my street for the past week taking down huge trees that shake the earth. He started soaking right around then. Maybe that has something to do with it?
