World’s Best Cat Litter Review
February 24, 2010 · Written by Joel
A review of something I haven’t personally test per-se, but my cat has. World’s Best Cat Litter has a great name, and has some claimed green credentials. Most normal cat litter is made from natural clay (or sodium bentonite), which is formed into pellets and dried. The clay is strip mined from the earth in a destructive process that leaves a indelible mark on our environment.
The corn used to produce the World’s Best Cat Litter are the same corn varieties approved by the USDA /EPA/FDA, and EU European Union for food use. This corn is also used to produce many ingredients, including corn sweeteners, food starches, corn oil, used in the production of high quality food and pharmaceutical products. This corn and/or its components are also used in the production of animal feeds.
Since the corn used is all natural and biodegradable, it is very safe for people, pets and the environment. There is no silica dust for you and your cat to breath in, if your pet ingests the litter it is digestible (so no need to be concerned about intestinal blockages), and over time the litter will naturally degrade and not be sitting in a landfill 100 years from now.
It claims to have unsurpassed odor control, and while it wasn’t the best in the world on that score, it wasn’t bad and not really noticeable as we clean the box regularly. Some people said their cats have not liked the texture, but ours didn’t seem bothered. It’s flushable but I didn’t try that as there’s no point (and I think it’s still not recommended in California at least).
Clumping was pretty good and scooping not a problem, overall it worked well. I would prefer to some degree that it wasn’t made of edible whole kernel corn that could be used for human food, rather than cat’s waste, perhaps looking at using some sort of inedible corn by-product.
You can buy it now from Amazon and pet stores of course!


I like the fact that the litter is digestable so it wont hurt your kitty’s belly. I have quite a few friends with kittens and have had trouble finding green cat litter but World’s Best seems like a great option
This was on sale and I purchased 3 bags because I had coupons. I have tried it for a week, and for me, it DOES NOT do as good of a job as it states. I have one cat and when he uses it, I immediately have to get it out because of the smell. I normally use the Arm & Hammer and I’ve found that it works the best. I am 50 years old and have had cats my entire life. I have tried most litters, if not all, and this litter just doesn’t get rid of the smell and does not clump well either. Sorry. I was hoping it would work.
I have to disagree with Diana. I’ve been using this cat litter for almost a year and have found that it clumps just as well as clay litter. As for eliminating odor, I’d say this litter is average. From my experience, there isn’t a cat litter out there that can eliminate the smell of urine.
What I like the most though, is that it’s biodegradable. Just can’t get myself to dump a plastic bag full of dirty clay litter in the trash anymore.
I think it depends on your cat(s) and perhaps their diet and where the litter box is kept. It’s worth trying to see if it works for you, but people have had opposite results it seems! Thanks Jason.
