Set it aside, and pile all the dirt right next to the hole. Once the hole is dug, slip off your knickers, use whatever posture works for you, and let the chips fall. Simply dig the hole under and around the feces, making sure that none remains on the surface. Ideally, no-trace campers should rely on leaves, pine boughs, snow, or even smooth stones instead of toilet paper. These natural wipes can go right into the cat hole before covering it.
Toilet paper degrades slowly and is unsightly if dug up by animals.
Use as little as possible. If you choose to burn it, use a campfire rather than lighting the paper in the cat hole. Burning toilet paper is risky at best, as one poor soul discovered after his flaming tissue paper ignited a 450-acre wildfire in Washington state during the summer of 1989. When covering the waste, use a stick to stir in the first handful or two of soil. This puts microbes in the soil in contact with the waste and quickens decomposition.
