My little guy has poopboots every morning after spending the night running and pooping and running through the poop on his wheel. It's a fairly common thing for hedgies to do. Each morning, he gets a little footbath and snuggletime. Then he settles down to sleep during the day with clean footsies. I worked out the same arrangement with Miss Satin: she worked hard during the night to make messies, I worked hard during the day to clean those messies up.
I've tried talking to them. I've offered litterboxes filled with different things. I've pinned up small signs. I've pointed out that they can avoid the dreaded footbath if they poop on NOT the wheel. Doesn't seem to make a difference. It is the hedgie way to run through poop.
It does get a little better as they get older - babies are such poop machines. But, in the end, best way is just to expect that they'll have poopboots and develop a routine to clean them up in the morning. And, one day, when they don't have poopboots, not only will you NOT be happy, you'll find yourself alarmed. What happened? Didn't you run? Did you not poop? Are you sick?!?!
Poopboots are good. Messy, but good.
