Rated 5 out of 5 by from BEST CAT LITTER EVER! Great for cats w/ allergies BEST UNSCENTED CLUMPING CAT LITTER EVER! NO dust, much less litter gets tracked outside of the box way better clumping, and so much better for my cat with upper respiratory issues (allergies, congestion etc), and just all around makes cleaning the litterbox a WAY better experience. I can wait longer to fully dump and refill the box now, and don’t have to scrub the edges when doing so. This litter doesn't stick to the sides or go to the bottom. With potty it clumps at the top and is easy to scoop up, and the edges don't fall off (back into the litterbox, to get gross over time). With poo it's just as good as other litter. Covers up smells. I prefer unscented due to my cat who has allergies/respiratory issues, and let me say she has been breathing the best she has since she started having respiratory issues at age 2 (she's six now), the BEST. That is the main reason I tried this. I had to wait so long to try it due to living with roommates with cats who didn't want to switch litters (though we did use unscented, supposedly mostly dust free litters like dr. elsey’s precious cat), but this is ten times better for the reasons listed above. I wish I would've changed years ago! Thank you for this amazing product. Totally worth the little extra money. And I think it will last longer anyway, I don't need as much in the box! So, if you are on the edge--try it! Go try a small bag. You won't be disappointed. I will mention it does have a very slight corn smell, but not bad and you can't smell it unless you are scooping the box and it’s not unpleasant. Clay litter has a distinct smell, this one is just not the same smell.

Rated 5 out of 5 by from Easier life now! Love, love, love this! 6 month old cat switched immediately with no problems. Adore being able to flush it, avoiding having to go downstairs to garage multiple times a day. Happy to not have smelly garbage! I flush in small quantities to ensure no plumbing issues. I don't think it lasts as long as they say, but I totally don't care!!

Rated 5 out of 5 by from Lives up to the name!!! This litter really does live up to its name. There is no odor near the litter box. Scooping is super easy. Clumps very well. Flushes with no problems at all. Cats love it. Had no issues switching our cats straight over to this litter. Seems to last forever.

Rated 5 out of 5 by from The Best Kitty Litter I have been using World's Best Cat Litter for many years now. I started out using the "red" bag since I have 5 cats but found it too dusty. I switched and now exclusively use the "green" bag and I am very happy with it. The pieces track on the cat's paws but there is almost no dust. It is also "septic safe". Amazon has the best price and 2 day shipping for Prime members.
