Currently trying this one myself, clumps well but I have found it to be extremely dusty. I have always used Tidy cats and even though there is some dust it doesn't seem as bad as the pet supplies plus brand. Not sure if maybe I got a batch from the end, but I have issues with asthma and the extra dust from this litter seems to been causing me more issues lately.Pet supplies plus store brand clumping. Cats don't know it's not Tidy Cat---& saves a ton!
