I'm very sad to have wound up hating this product. The staff is very kind and has wonderful service but unfortunately I have never hated a litter more. Firstly, my cat became ill when I switched him to this which is enough to get me to stop. It is not dust-free and the powdery dust gets everywhere and created the BIGGEST mess. It coated the walls and floor around the litter box, became slimey and gross and took forever to clean. I had to throw out the litter box because I could not get the residue out.
