Wheatley's first meal was on the 31st of August. His second was yesterday (the 5th.)

I've been watching his cage and I still haven't seen any poops. Thinking that it might help I stuck him in some warm-to-the-touch water to promote some bowel movement.

Has anyone else had baby balls who didn't have a bowel movement for a while? How long should I wait before taking him to the vet? (also, in addition to this, is any vet ok? Or are there specific reptile vets?)
