Clumping Cat Litter is rated 4.9 out of 5 by 3463.
Rated 5 out of 5 by from Best Cat Litter is True! This product is wonderful! I use it for my 2 cats, as they like it better than the Multiple Cat formula litter. One bag lasts an entire month! There's very little tracking outside the litter box, too. Clumps immediately. No leftover aroma (I clean box once daily). Natural, too. Made from corn cobs. Was recommended by my best friend, and I've since recommended it many times to others. As long as I have kitties I'll use World's Best!

Rated 5 out of 5 by from The best litter in every possible way! This litter couldn't have a more appropriate name! It's hands down the best for my cat household. I have two cats with very healthy digestive systems with two litter boxes upstairs. This room is right beside my bedroom and guest rooms. People cannot believe that there is no smell. As a bonus for me, it's easy to scoop and my oldest cat with some breathing issues has no problems with it. I hear people say that it's worth the extra cost. Well its certainly worth it but I actually find it cheaper than the other stuff because if scooped daily it lasts so long. I buy a 30 pound bag and with two boxes that lasts me a few months.

Rated 5 out of 5 by from Best Litter Ever! The #1 benefit of this litter for me is that it is virtually dust free. I am asthmatic and most litters have a bad effect on me, but not World's Best Cat Litter. It also clumps very nicely and I love that it's flushable. I've been flushing it for years and haven't had any problems.

Rated 5 out of 5 by from easy to use I bought the cat litter originally as I travelled a lot for work and took my cat with me. We had a few nights of staying in hotel rooms, and I was looking for something that was biodegradable and glad I found worlds best!! it really is Worlds best ! it may cost a bit more than other litters out there, have tried a few others and the dust etc from the others my cat did not appreciate. worlds best is so easy and It seems to last longer than other litters. no smells no dust and convenient.

Rated 5 out of 5 by from Great litter Our Rooney was raised with this litter so we wanted to stay with it and we couldn't be happier. The clumping factor is great and it reduces odor so well that we hardly know its there. I'm glad to know that it is a lot better for him then other litters.

Rated 5 out of 5 by from Bogart Cleans Up!!!! Bogart is 10 years old. At the age of 6 he decided he wasn't going to cover up his you know what anymore. Now that we use World's Best he's a new man. He no longer runs away and looks for the first open window to 'freshen up'...he is spending a little more time in the box, thank you World's Best!!!!

Rated 5 out of 5 by from THE BEST EVER! I LOVE THIS LITTER! That about sums it up..I love the clumping and how they don't break apart. I love that it can be flushed away..the best odor control and most importantly virtually DUST FREE! My husband has bad allergies and this litter with it's low dust really helps. My cat used to just sneeze all the time with his previous litter but no more! Lastly..the litter lasts a LOT longer when you have so little of it being wasted when you sift. There is nothing I wouldn't do for my boy Boris and he deserves the best this is why I will NEVER buy another litter for him! Thank you for all you do for our fur babies that we love!

Rated 5 out of 5 by from Best litter I've ever used! I have been using World's Best Cat Litter for a little over a year now and I love it. I found World's Best Cat Litter during a period of time when my oldest kitty, London, was just diagnosed with Plasma Cell Pododermatitis (aka Pillow Foot). The pads of her feet were often cracked, swollen and bleeding. I wanted a litter that would be safer for her and that was not clay nor full of perfume. World's Best Cat Litter is super absorbent! I love the fact that it's a natural product from whole-kernel corn and offers great odor control. I have three cats and believe me, there seems to be a cat in the box all the time. The best thing about it, well, Chloe my dog often breaks into the litter box for kitty roca (ick!),and I don't have to worry when she does eat some of the litter.
