We have a two cat house. In the past we have used other brands of kitty litter (Tidy Cats, Fresh Step, and some generic brands). We finally ended up buying this brand (though bit pricier) since the other litter either did not clump, left lingering odor, or was too dusty. Since starting (about 4 years ago) to use this product we have never gone back to other litter. For us it is worth the extra cost for the benefits. No cat litter is going to completely remove odor but this one seems to do the best job for us. The other thing I like is when I fill up the box there is no dust. Cleaning out the litter and results in no dust being breathed in. I highly recommend this product. We purchase regularly for last several years at many different prices.
