Should i change the bark in my snake's tank?

Use newspaper a few times and see how much that little snake can actually urinate.. That will make you completely change out ANY substrate each time they have a bowel movement.

That's just disgusting..

This is definitely true!! I never realized exactly how much a snake pees until I got my second BP and she was put directly into a tub with newspaper. Even when I had my other girl in a tank I would spot clean everyday and would completely break down the tank for cleaning/sanitizing and fresh substrate every other week.
