I do not remove any of my snakes for feeding. Granted, most are on newspaper, but my sand boas are on coconut bark and my mom's snow corn snake is on aspen. Yes, sometimes they eat a little bit of the stuff.. but what on earth do you expect a wild snake to do? Snake digestive juices are one of the strongest natural substances there are.

I also know that Adam who has more than 200 ball pythons, feeds all his on shavings with no problems.
