Our frog, Mippy, will only poop when he's outside his tank. We have to put him in his critter keeper that we use to house him while we clean his tank for him to poop. We don't even add water for a bath. He just refuses to poop while in his home. Anyone experience this? Is it because he knows the poop will bother him in his tank? Or is it the stress of moving him into his critter keeper causing him to poop.
