This cat litter definitely helps to keep odors out. All of our friends that come over to our apartment always say that they would have no idea we even had a cat except for the cat toys on the floor. Never any smell with this litter! I've bought it at my local Target, Giant, and Pet Valu. More and more stores are starting to carry this litter. We have been using it for about 5 years now and will never use another cat litter again.
