I was incredibly disappointed with this product. It smells awful (I don't notice any difference in smell when the box is clean or dirty, it just smells terrible all the time), it's EXTREMELY dusty, it doesn't clump well (the clumps fall apart when I try to scoop them up) and even the bag is of very poor quality - the reseal mechanism ripped off the very first time I opened the bag. My cat ends up leaving dusty paw prints everywhere after using the litter box, and she even got an eye infection from the dust billowing into her eye while digging. I'm not even going to finish off the bag. What a waste of money.
I tried this for a cat who was reluctant to use the litter box. He loves it - no more accidents since I've started using it. It clumps substantially better than any other litter I've tried and it seems to do a better job of trapping the smell as well. The only downside is that it is very lightweight so cats who like to cover their mess vigorously will send this litter flying all over the floor near the box.
