I did quite a bit of research before ordering this product for use in an automatic litter box. It does a great job of clumping and, best of all, as long as the cat covers over his business, it kills the smell. I will continue ordering this product as long as I use this litter box. But be careful when you order because some of the listings for this product are eligible for free shipping and some are not.
