Yes; I agree with the conditions your pacman is housed in has led to stress, therefore not eating.

However; I don't agree with you (Ivory) saying that a mouse is NOT right in this situation. It's very applicable in this situation - it's not impossible for pacman's to digest a mouse, especially prior to it not eating for awhile. I've seen a few experienced pacman owners force feed mice to ones that don't feed as readily or are wild caught after a few weeks. Everything has worked out fine.
