For the BP enclosure I use a mixture of Forest Floor Bedding and unscented cat/rodent pellet litter made from recycled newspaper. It has made a huge difference for odor control. At shed time I only use the forest floor bedding because the newspaper pellets tend to suck the humidity out of the air.
For my ratsnake I use only Forest Floor bedding. She doesn't stink nearly as much as Spot (sorry Spot) and she will sometimes burrow under it.
