I just adopted a bp about a month ago. When we first got him home we were using newspaper (unprinted) in the bottom of his cage. About a week ago we changed over to Aspen. Since that point he began to move around less and spent much more time in his hide box. Last night when we pulled him out we found that his underside was a bit pinkish. We immediately pulled the Aspen out and went back to the paper but I wanted to see if anyone else has had this happen or if there is another reason that he would have the pinkish color. He has been eating fine and the temperture in the cage has been within the right range. So I really can't think of anything else (from my lack of knowledge and expereince) that could have caused it.
Thanks!
Bryan
