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 4.7 out of 5 by 539.
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 LITTER EVER!!! Okay, I really am not one to write reviews but I find that when you are trying to look for good cat litter, I spent most of my time reading reviews so I thought I would share my experience so far. By far this is the best litter I have ever used. I have 5 cats and 3 are large Maine Coons. Controls the odor, it clumps without falling apart when I scoop it and to top it off, I like the gentle scent of corn. The bag lasts, probably because it clumps so nice you don't use as much. Its a little dusty when you open the bag but when scooping or pouring, the dust is minimal. I absolutely Love it because the last litter I used, I am still cleaning it off my fixtures and walls. It does track onto to floors some but I haven't found a cat litter that doesn't stick to your cats feet or get thrown out of the box. lol I really can't recommend this enough. Such a happy happy customer here. My search for a cat litter that I can live with is over!!!

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 5 out of 5 by from Really the BEST Cat Litter We would like to give this litter the extra-star and tell you: "Try it out!" We had cats before and used different sorts of litter, mainly clay. We tried this out ones and were amazed by it. Unscented, natural, and effective!!! We really like the fact that it is flushable, what safes time, money, and effort. The clumps are mainly firm and doesn't mix with the clean litter. We use one box for many days, flush daily the clumps, and usually only refill it, without cleaning the box. What safes again, time, money, and effort, in contrast, the muddy clay in the box needs to be cleaned regularly. Also the clay and/or scented litters often reacting with the urin what creates a terrible smell, for cats and humans. Allergic reactions are often caused by chemicals in the litters. Easily to avoid with this litter. By filling the box there is nearly no dust, the transfer after the use is normal.

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 My favorite litter Worlds Best now carries scented pine and lavender that is really smelly to "multiple cat formulas" and other varieties. I tend not to buy scented litters because they stink terribly, worse than the cat poop in some cases, and they're overpowered. A cat's sense of smell is 15x an average human so imagine what it's like for the cat. As for the other World's Best varieties, they seem to be wetter and don't clump as well. This "green bag" formula is dry and clumps the best. I like the fact that it's a corn vs clay litter and the cats seems to like it too.
