It won't be a problem. I never use newspaper, and feed all my snakes in their enclosure. A little over 40 snakes on aspen, and I haven't had a problem yet. Once in a while, one will get a piece stuck in his/her mouth. They either get it loose themselves, or I get it with hemostats. By the way, I have never seen aspen in the "poop" from any of my snakes, and I KNOW some gets swallowed occasionally.
