I add some pine pelleted wood to my sand. It breaks down into a sawdust and makes the sans a little fluffier but you can still clean it with a kitty litter scoop. To help it break down faster from the pellet to sawdust, you can spray the pellets with water a few times before mixing them in with the sand. The pellets are very absorbent . I also mix DE in with the bedding no matter what it is. It helps keep it drier and helps with any odors. Hope this input helps.
