You're very unlikely to get him to not poop in his wheel. It's what hedgehogs do - they tend to potty on the run, and most don't really care if they do it on their wheel as well, even though it doesn't really go away like it would running outside in the wild. Very occasionally there's a hedgie that will stop & get off the wheel to poop, but it's not common. For most owners, daily wheel cleaning and foot baths to clean off poop is part of having a hedgehog.
