I had firstly the baby powder version, it was very good, clumping and less dusty than others.
Then I wanted something "cleaner" for Persian noses, so I purchased this unscented version.... Disappointed!
Is not clumping almost at all, and does not cover smells even from the first day. I have deep litter boxes, and I always put 3-4 inches of litter, as my cats prefer it.
It might be just this batch, but still not happy, for this price I was expecting a better product.
