Ideal for homes with one or two cats, Clumping Formula is the unscented clumping cat litter with outstanding odor control and tight clumping ability. And because they'll scratch and cover, this quick clumping cat litter provides maximum odor control, while minimizing dust and tracking around your home. Unlike clay cat litter, World's Best uses a patented process to compress naturally absorbent corn into concentrated granules that trap odor and form tight clumps on contact, so a little goes a long way.

Rated 3 out of 5 by Not for Asthmatic Cat but OK otherwise I've used World's Best before but now use Dr Elsey Senior because my cats have urinary tract disease (and I am allergic to it, makes me sneezy). I notice my foster had coughed some muscus a few times around litter box, (she has asthma) so I decided to use this for her - I saw some suggestions online that since its "dust free" to use for asthma cats. It was much worse than the crystal litter, coughing muscus everyday around her box. I now have her on Dr Elsey Respiratory and she is not coughing around the box late at night. As far as clumping and all that World's Best has always been better litter compared to other brands, but if your cat has coughing issues this might be agitating it depending on what they have. As far as smell I have never been a fan, I think it smells very barn yard even when kept clean, makes me sneeze, but I think it smells better than Swheat Scoop at least. September 22, 2016
Rated 5 out of 5 by World's Best Cat Litter Clumping Formula Love this product. Love the way it clumps so it can be removed so easily. Other litter that I have used could be removed but I had to dump out the whole litter box after 2 weeks because of the odor and wash the litter box and then refill the whole box. With world's best I have 4 cats and I just remove and add to it when the box gets low. And I only wash the litter box twice a year because there is no odor. And the fact that I can order it from Chewy I don't have to purchase at the store and carry it home it comes right to the door. September 18, 2016
Rated 4 out of 5 by I love it; I wish my cats did. I love the non-dusty nature of this litter and how nicely it clumps. And it doesn't smell like the perfume section of a fancy department store. But, my cats, given the choice between this and clay litter, choose clay every time. Maybe if the pieces were smaller? They do seem rather coarse and sharp and I can imagine it feels uncomfortable to stand on with their paws. September 15, 2016
Rated 3 out of 5 by ok product Does most of what it claims. Clumps great. Doesn't have a strong smell but that also means that it doesn't cover up feces smell very well either. September 20, 2016
Rated 5 out of 5 by Good product This product seems to do well. It clumps well and absorbs odors. Liked that it was delivered with free shipping. September 17, 2016
Rated 5 out of 5 by awesome litter I love this cat litter! I have a large Bengal cat who is 17 years old and I was using a pine litter, but after a few days the amonia smell was terrible. With this litter - there is no amonia odor - just a sweet corn smell. It is easy to scoop, and I do flush some of the 'clumps of urine', but since he goes such large amounts at a time, I scoop it into the garbage and it can stay there for days and still - no odor! Would buy again. Yes - it tracks, but since it is flushable - I don't worry about it clogging drains. #I keep his litter box in my bathtub#. August 31, 2016
Rated 5 out of 5 by This is the litter that suits my needs and my cats' the best by far I really needed a litter that my cat would find as appealing as possible because she formerly lived with a cat that bullied her in the litter box so it's a sensitive place. This seemed soft and dirt-like and did not have any weird added scent that would discourage her. It also does not create too much inhalable dust like clay litters. She approved, which is the most important thing! For me, it's also a great litter because it is FLUSHABLE. It's never caused any problems for my toilet, and I've been using it for about 6 months now. (My cat is fully indoors so I don't have to worry about her having toxoplasmosis and spreading it through the sewer system). It also clumps well, making the litter very easily scoopable if the cat hasn't accidentally walked through it, which normally doesn't happen if I clean the boxes daily. Some litter does get outside the box because she kicks it out, but I don't find it anywhere else so I don't think it tracks very well which is also wonderful. January 5, 2016
Rated 5 out of 5 by Worlds Best Cat Litter is the Worlds Best Cat Litter I work with many kitties as a rescue and have many kitties. I have tried numerous cat litters and none come close to the World's Best Cat Litter. All of my kitties love it and none have never not used the box because of the litter. Even teaching little ones to use the box for the first time made the transition easy. September 6, 2016
