Are people talking about the same litter?
I have a feeling that some of the negative reviews have mixed this product up with a different one. This one has large lumps of white crystals with some blue and you need to use a scoop with bigger holes.
Urine is absorbed (discolours the white crystals over a few days). Poos dry out and are easily removed. There is another product with finer sand like crystals that clump with urine which is dusty, but it is still good. Prefer this one, no smell, lasts much longer.
