I use Nature's Miracle. It has very little dust, negligible, and it clumps well. It's 100% natural (corn based) but does not track little yellow paw prints all over. It's also flushable
and it covers odors pretty decently. It also has a nice pine scent.
I used Swheatscoop for a while, and it worked well, but I did not like that the pee would stick to the bottom. It made it *really* hard to scoop out.
With the Nature's Miracle, I gently shake the litterbox from side to side and front to front to loosen the clumps because my cats always pee against the walls of the box
and that way the clumps don't break apart.
