Just how much poop are we talking about here? XD I love their faces, particularly the black tails. I don't think I have enough experience yet, but I'd love to have one someday.
Soon after you feed them, and often for a day or two. The consistency is a cross between baby food and velcro.
It is unlike python or boa poop. The smell hits you as soon as you walk into a snake room with a dry in it.
