Product Review: World’s Best Cat Litter
It really lives up to its name!
World’s Best Cat Litter is the finest alternative to using clay based clumping litter. We made the switch last year after reading about the dangers of clay litter. Living with three cats who use four litter boxes throughout the house made us very conscious of just what we were putting in those boxes.
World’s Best Cat Litter is made from whole kernal corn, which means that it’s safe to breathe, safe to ingest, and safe for the environment.
Problems with traditional clumping litter
Clay cat litter presents many risks, both for your cats and the environment. It’s active ingredient is sodium bentonite, an impure clay which is strip mined. This process alone is harmful to the environment. Another big environmental concern is that, like styrofoam, it never breaks down, which makes disposal a big problem.
The problems with sodium bentonite hit closer to home as well. When your kitties are scratching around in their boxes, they tend to kick up quite a bit of dust. Not only does kitty inhale this dust, it also settles in their fur as they’re doing their thing. When kitty cleans herself, she ingests tiny particles of this product that is meant to expand, and harden when it comes in contact with moisture. It has been associated with digestive, and respiratory problems in many cats. I shudder to imagine the harm it could do to the family dog who enjoys eating “cat cookies”!
How is WBCL different?
As I mentioned earlier, this stuff is made from corn! It clumps naturally, doesn’t produce much dust, and best of all, it’s completely edible! If your cat licks it from her fur, no problem. If your dog treats himself to “cat cookies”, they’ll do him no harm. Granted, as a food product, corn can be hard on your pets system, it’s certainly much much better than clumping clay that can do permanent damage.
How does it stack up in our house?
We’ve been using WBCL for about 1 year now, and have been extremely happy with it. It clumps like a dream, and DOESN’T stick to the bottom of the box, making kitty clean-up a breeze.
The extra strength product (recommended for multiple cat households) contains odor very well. When we started using WBCL we had three lovely cats who used 3 - 4 different litter boxes. Walking around our house, you’d never guess from the scent that there were two boxes per floor.
We all know that cats don’t like change, however, with one quick sniff, our three accepted WBCL right off the bat. If your cat doesn’t like the litter you’re using, believe me, she will let you know, and it usually isn’t pretty. According to WBCL’s website, cats will prefer the softer texture, and natural scent.
At approximately $30 per 34lb bag, it’s priced a little higher than clay litter, however the benefits of this product far outweigh the cost. It is available at Pet Value locations across Ontario. To find the closest location to you, use WBCL’s location finder. Check your local pet stores, and if they don’t stock it, request it!

Thank you so much for this post; I’ve been suspecting bad things about the traditional clumping cat litter, but I was afraid to find out if the suspicions were right.
I’m glad there’s a good alternative, and that it actually works! I really want my two wonderful, loving cats to be happy with us as we are with them. As they are increasing in age, I am starting to fear anything that might cut into their lifespans.
Looking forward to heading to Pet Valu and (hopefully) finding this cat litter there!
Thanks for the comment! If your Pet Valu doesn’t have it in stock, I’m sure they’d be happy to order it for you.
My cats love it
