After having cats for nearly 20 years, I have been looking for the PERFECT litter that does not track and low dust. We use Arm & Hammer unscented clumping, still tracks but gets dusty towards the end of its life. We tried a pine litter, that does not track, but the cats HATED it. I also tried using litter mats, which I thought was a good idea. Well, the cats thought differently. Several of them urinated ON the mats!!! Needless to say, we no longer use the mats and the cats are very happy!!! Good luck!!!
