tomorrow is my day off, I am gonna clean out his cage and put in all aspen and see if the dots come back. Right now hes on a mulch bedding that said it was safe for reptiles as it was cedar free.

Also might add, I have had him since 03/13/07, he has yet to miss a meal, and he has yet to take a crap, even AFTER his PERFECT (one complete piece with no aid from me what-so-ever) shed...
