I never used clay cat litter for my fur balls -- I used chlorophyll cat litter - it's little green pellets that look a lot like what we used to feed my pet rabbits. It was easy to clean up if they did dig, wasn't dusty, didn't track at all, and absorbed the odor well. It was flushable in small/medium amounts. I used to get it at the local supermarket in NJ, among the normal kitty litter. It came in smaller bags than the clay litter, but it seemed to last for quite a while. *Tigger* [Posted in FML issue 0348]
