I was hesitant to try this letter due to the cost and subscription model. However, it is the best cat litter I've found in the 30 years that we've had cats as part of our family. It doesn't have a perfumy scent, has very strong clumping action and is cleaner to deal with. We have a cat that really likes to dig and throw litter around and this tracks much less than the other more commonly found brands. I also like that it's better for the environment. It is practically dustless, which is better for my asthma and has got to be better for the cats (so they are not inhaling the dust). I was worried about the subscription purchase model, but find that I can easily delay or cancel, so I'm not buying too much, and can even order early if I need to. I have been pleasantly surprised by the quality of this litter and by how easy it is to purchase and use. And, since I purchase the 5 pack at a time, the price isn't that much higher than the more popular pet store brands.
