There are people that have their Dums on paper and give them hides, just like a BP setup.
I personally have mine on coco chips with no hides. I think it's easier for him to burrow than aspen. He had a hide at one time but it seemed to be more of an obstacle, so I removed it. I don't have too many snakes, so I prefer to give them what they seem to like over my added labor and cost.
