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.

Key Benefits

  • Powerful, concentrated formula traps odors and forms tight clumps on contact. No more nasty ammonia smell and clean up is a breeze!

  • Environmentally friendly: flushable formula is safe for septic and sewer systems
  • Quickly forms small, tight, easy to scoop clumps that result in less litter waste — a little goes a long way
  • Pet, people and planet friendly — a highly effective product that you can feel good about using

Rated 5 out of 5 by 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. December 1, 2016
Rated 1 out of 5 by 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! January 10, 2017
Rated 5 out of 5 by Best of All Formulas I've tried a lot of natural septic safe litters - walnut, corn, pine, wheat across the multi-cat and single cat formulas. I think WBC single cat formula is the most effective at clumping and holding in odor. It is expensive - and you can cut or substitute part of it with other clumping litters or even feed grade 'chicken crumbles', which are much cheaper at barn and feed stores but are not sprayed with gelatin so do not clump as well. When this product is on sale, I always buy it. January 9, 2017
Rated 5 out of 5 by I love this litter (if you can love litter, I mean) This litter isn't dusty, lasts a long time and the boxes are never smelly. What else can you ask for? I believe it's flushable but that's not really a good option for me but may be a selling point for someone else. January 11, 2017
Rated 5 out of 5 by Great product. I love the scent and ease of scooping this litter. January 14, 2017
Rated 5 out of 5 by Quality for me AND for kitty! This is less dusty than clay litter, not gummy/heavy. Kitty accepted it immediately. Does cost more but worth it. Chewy sent it SO fast, maybe next day I got it? Amazing. January 7, 2017
Rated 5 out of 5 by I love this litter When I found this previously,there is no other I would ever use. No smell ever! January 5, 2017
Rated 5 out of 5 by Literally is the BEST cat litter! I've had many cats over the years and tried just about every litter out there and none of them I like more than this! Just can't beat the price, all natural, safe to consume, clumping, and flush ability of this litter! January 2, 2017
