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.

World's Best Cat Litter Clumping Formula is rated 4.6 out of 5 by 502.
Rated 5 out of 5 by from Love this litter It is so easy to keep my cat´s litter box and rest of my apartment clean and clean smelling with this litter. The litter box is in my bathroom so it is so easy to scoop out my cat´s waste and put it directly into the toilet and flush. No more bag of waste that may smell, or muddy looking floors because of the tracking of clay litter that dissolves on the floor if there is any moisture on it. If some of this corn litter gets out of the box it is easily swept up leaving no residue, and if you like to walk around without shoes you do not get the feeling of stepping on sand, as with clay litter. Another bonus is that it is not as heavy as the clay litter so adding litter does not turn out into a strength training session trying to get the fresh litter to the litter box area if the fresh litter is kept elsewhere. For extra odor control, mixing in a sprinkle of baking soda does the trick, but it so easy to keep the litter box clean that the odor factor is not a problem.

Rated 5 out of 5 by from Best Cat Litter Ever I do not care for cats. Strictly dog person. But I found myself being "gifted" 2 very young abandoned kittens in the winter. It was to cold to leave them in the barn. So of course they have moved in. For a none cat person this is the absolute best cat litter. Not scented, low dust, tight clumping, lasts longer than any litter I have tried. Tried National brands, cheap litter, scented litter - none compared. It makes an irritating task less irritating and easier to keep litter boxes "low profile". We are now shopping for a cat tree.

Rated 1 out of 5 by from World's Dustiest This litter is incredible for one day. ONE DAY. Then after pawing at it and using it, it turns to dust. I have little paw prints all over the sofa and carpet. Litter dust on every surface he touches. Litter dust all over Walter's face! Sneezing! Runny eyes! Itchy ears! I seriously don't understand how people love this litter. It's great that it's biodegradable- I'll give you that. But everything else is less than desirable. Think twice (especially if your cat has respiratory issues or is prone to them) or buy the smallest bag to sample this first!

Rated 5 out of 5 by from The best litter ever - worth the money I've had cats for over 20 years and have used just about every kind of litter - clay, pine, cedar. In my opinion, World's Best is exactly as it claims to be. It absorbs both moisture and odors. I use less of it than I would with other litters so I don't find it expensive. I had stopped using clay litters years ago when one of my cats started spitting up a foamy substance which turned out to the be the dust from the litter. I had switched to a pine-based litter for years but my new kitten didn't like it. (My vet speculated that it was the texture.) I tried World's Best after reading online reviews. I had a litter box set up with both of kinds of litter to "transition" but both cats immediately used the only the box with World's Best. Due to recent severe weather in my area, I had to make do for a few days with another litter stocked by my local convenience store. I was surprised at the odor that I could detect even though I was scooping the litter daily. Now I make sure that I have a back-up bag of World's Best.

Rated 5 out of 5 by from 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.
