I love this litter because it gives me incredible peace of mind. The crystals contain a color changing technology that indicates any health problems your cat may be suffering from, so you can address issues early. Cats are notorious for hiding illness, basically crawling into dark corners to suffer in silence. With this litter I feel confident that my kitty is healthy and that if any problems were to arise, we would catch them early. It's also had the added benefit of being more smell absorbent than other litters we've used. We live in a small open floor plan apartment and keep the litter box in a closet in the bedroom because that's pretty much the only place there's room for it. And yet, somehow, our home has ZERO bad kitty smell. I love it.
