It is the best sand I have tried among many and I wouldn't change it for anything. It may seem expensive but it is so high quality that it lasts much longer than the cheaper ones.

I bought the product to replace the fast acting litter from the same company, after my cat developed an allergy. The odor control is at the same level as the fast acting, except for the first five minutes where you notice a slight smell (open litter box in a relatively small bathroom). The clumping is also at the same level. I believe that slightly less dust is produced compared to the fast acting. It is very positive that it is odorless and bothers the cats less. With cleaning 2 to 3 times a day and washing the litter box once a week after sifting all the litter into another box to reuse it, the package definitely lasts 1.5 months. For the initial filling of the litter box, which is very large (dimensions 71*55 cm), I needed about 12 kg. The cat used it immediately. Overall, after using this particular litter for a period of 3 months, I am very satisfied.
