I used to use plain newspaper as substrate for all my ball pythons. I have a few ball pythons who tend to crawl underneath the paper, and when I go to get them out, they snap at me because of the movement of the paper. I want to get rid of the paper and possibly move them to ?aspen? or something else if you know of one that you think is better.

I am worried about them eating the substrate. I feed them in their enclosures, not in a "feeding tub", so what are the risks of them eating the aspen bedding?
