I have three adult cats, and Dr. Elsey's cat litter is the best litter I have ever used. It is virtually dust free. I say virtually; I do not notice any dust at all when I pour it in the box or when I am cleaning it. The litter clumps very well. Its odor controlling ability is far better than any other litter I have used also. It may cost more than some brands, but you are not buying useless dust. Its weight is actually clay litter. So it might just seem more expensive. One draw back is the 40 lb bags are not as easy to handle as litters that come in buckets. You might want to save a bucket or buy a bucket to pour Dr. Elsey's litter into. I never want to go back to any other brand. Moisture Absorption The litter is an excellent clumping litter. Ease of Cleaning It is easy, but you have to maintain as with all litters. Odor Control It outlasts any other litter I have ever used. Ease of Use The big 40 lb bags are not as easy to handle as the smaller 20 lb bags or the buckets other litters come in.
