I use aspen bedding in my python's tank. I know that immediately the suggestions will probably come in to use newspaper, but before I really consider making this switch, what do I look for when I am searching for areas where my BP has urinated? I spot clean the tank daily, but I'm having some trouble locating where he's urinating. Are there telltale colors of the aspen or smell?
I know he has to be going, but I don't know where!
