I have digital thermometers and the probes are under each hide, taped to the glass, under his bedding. The hot side temperature will be warmer right on the glass, compared to up on his bedding. So I usually turn it up a little bit to compensate. Maybe i should not do that.
My apartment is always 70F so I had a small infared bulb over the cool side to warm it up a bit... never really checked the cool side in a while.
He ate since the last regurg, so if he does it again, maybe the mouse is too big. I can't find live hoppers, and I don't really like feeding frozen.
