Not too sure about this litter yet. I believe I bought the clumping version but it doesn't do much in the way of that. I was very surprised there is some perfume in it. I want to contact them to find out what the clumping agent is, also. In the clay litters I checked out, it's the type of clay that makes it clump. I did add a bit of leftover A&H scooping litter (which I like but the dust is killing us all and my baby has a lung nodule).
Could not recommend this litter, but I might mix it with others. Nature's Miracle is in first runner right now, although I'll mix that too. Hate the odor out of the bag, but I think it dissipates as it didn't bother my asthma or breathing later. Yesterday's News just closed my lungs down. Didn't like the way it performed either.
