Cool. Thank you very much - I actually have a uth but no stat. It's very small and doesn't seem to do much warming under just 1" of aspen. I have a digital thermo as well with a probe - display is on the wall outside of frame. On your recommendation, ill move the light over to the cool side n get the temp up. Will use the uth to warm the ground on the warm side n see if things change with his appetite. As for the skin issue, I've seen him drinking on more than a few occasions and he's never out of water. Should I maybe try n soak him? How warm for how long?
