I raised the tank off the heating pads slightly but increased the temperature hoping to keep him from burning himself but provide more warmth. He has burrowed under the bedding down along the colder side since my previous post. As a sort of separate aside: I gather that bps generally shed every few months and he hasn't since I got hime...this couldn't be behavior associated with an impending shed could it? From what I've read, the eyes blue and the color looks lighter around that time which is not yet the case with him.
