I am using a UTH, but he doesn't sit directly on top of it, and there's a decent substrate covering (some coconut dirt stuff, can't recall the name) I don't have a thermostat, but the thermometer stays at about 75 and the heated portion of his tank isn't warm enough to do more then make my hands nice and toasty after a few minutes. Pretty sure it's not a burn, since its not on his underbelly, but higher up on the sides, and its only in that spot near the messed up patch of scales. I'll try to get some pics up later, for better reference.

I'll be getting some hoppers for him for the next couple of weeks, until he's better. He's just a bit underweight, which I hadn't realized, so would feeding him smaller mice bi-weekly help to get him back to a proper weight, or should I go for the weekly instead?

I will be cleaning his cage daily, hadn't thought of that, thanks. I usually clean it after he poos.
