I love the litter, it clumps great(I had stuff that hadn't been covered, and I covered it, came back a few minutes later it was one cohesive lump), smells better than most clay litters(not all), and my cats love it! The crystals are only slightly larger than most clay litters, making it clump well, but still not irritate my cats' soft paws. My only objection is the price! I am going to try Papurr, because of the reviews I've seen, it's cheaper, and the fact that it is recycled.
