That jarred my old stagnated imagination, Joe; those Tidy Cats buckets are great for stuff like we're talking about here, especially in a small shop. We used to use that stuff in copious quantities, and I still have several of the buckets left. When they are empty, a good rinse with the hose takes the residual dust out, and when they are dry, they are good to go. We don't use much of the stuff any more, though, we're down to only one kitty and he uses the outdoor latrine most of the time.
