exc litter, we have 2 cats and cat box odor not a problem. We love that we don't have the high power perfume odors that most litters have. We don't like that, nor do the cats. Plus, perfume plus cat box odor is a much more unpleasant blend than natural clay doing its job in the litter box. It's still easy w/ a wide metal construction spatula to clean the box even though this is a non-clumping variety
