Rated 5 out of 5 by from Love It I volunteer at a cat shelter and we changed to "World's Best" about a year ago. It has made such a difference in helping to control odor. We use most of the formulas but my favorite is the clumping - it is all great - The World's Best" !

Rated 5 out of 5 by from Finally Easy Scoopin' We have 8 cats and found every other clumping litter would unclump and fall back into the box while scooping. With this, I just scoop and it all comes up in big lumps and stays together until tossing it into plastic bag. No dust which is safer for all kitties. We haven't tried flushing it yet but if we could without it clogging the pipes, it would save us on our garbage bill!! Much easier and cleaner and it does last with all 8 cats using 3 big boxes a good 20 days or more.

Rated 5 out of 5 by from Absolute The World's Best Indeed The only cat litter I use...totally heavy garbage bags to carry to the curb anymore!!! Worth the cost!! Too bad Wal-Mart Canada has stopped carrying this fantastic litter. The thing I miss about the little is the Lavender scented...No longer available here in Peterborough or Campbellford, Ontario, Canada. My cats seem to love this litter too.

Rated 5 out of 5 by from All around -- I just love it!!! I initially tried this because it was just corn. (I liked that!) Then I was elated to find --- YES, it does clump, there's no lingering odor, and though I don't know what's involved in the process, if there are chemicals at all they've got to be fewer than in those made from -- who knows what; so I'm especially thrilled that I not only don't have to breath any dust, but especially the chemicals in that dust. I dispose of the 'poop' in the toilet and the urine soaked corn I fertilize my flower beds with. (And they seem to like it!) I am truly grateful for this product, for the fact that it works in all the ways that it claims to, and especially for it "naturalness."

Rated 5 out of 5 by from Excellent Litter We were encouraged to use this product. We are so grateful to have found this great product. My first thought, was that it did not take as much product to do a far better job of clumping. Then, I realized how long it lasted. Lastly that it does not produce dust. I will never use another litter.

Rated 5 out of 5 by from IT REALLY IS THE BEST! We live in an apartment and have been using World's Best Cat Litter for years. Good odour control and no dust tracking on our hardwood floors. Although on the pricey side, it goes further in the long run. I highly recommend.
