It's an on going debate which is better. Some people swear by feeding in the same enclosure. Others feed in a separate one. If your going with a feeding enclosure, skip the aspen and paper towels. Paper towels can be a real hazard. I personally use a feeding cage. One of the reasons for using a separate feeding cage is to avoid the ingestion of bedding materials. If you worried about feeding mode aggression, just use a snake hook or place a towel over the snakes head. That should calm it down no problem.
