I'll be getting some pictures of him this weekend and I'll try to get some of his belly. I didn't notice scarring anywhere else. I'm pretty sure they used a heat mat before but I'm not sure if their's was regulated. His new heating pad has a thermostat so it shouldn't get too hot for him. Should I maybe turn it down a little more for him? He has a thicker layer of aspen in there so his heating area feels warm to the touch but not hot (then again that is my lame human heat sense)
