Excellent
I've had cats all my life and this is the best litter by far. It clumps fantastically without crumbling when it's being removed from the tray. Consequently, nothing is left in the tray, so there are no smells and it lasts the full two weeks. I top the levels up to keep the required litter depth. Nearing the end of two weeks, as the depth starts to thin out, liquid can sink to the base of the tray and stick to the bottom. This isn't a problem but keeping a good depth makes removal easier. I wouldn't switch to any other litter.
