Sooooo just wondering ... new snake owner so I have lots of questions. I have been using crushed walnut shells but just recently saw a forum post on how terrible it is? The main point seemed to be that it causes impaction, but since I feed in a separate tank (without substrate) I figure that is a moot point. Any other pros or cons anyone has? Cause honestly at this point my snake seems to love it she has a wonderful time burrowing in it and it's much more attractive than paper towels. Wondering if anyone had anything to say?
