Clumping Cat Litter is rated 4.8 out of 5 by 4195.
Rated 5 out of 5 by from I no longer have to scrape the bottom of the box. I am so happy I found "The World's Best Cat Litter". It clumps instantly. I no longer have to scrape the bottom of the litter pan. In fact I didn't even have to wash the litter pan because all the urine was trapped by the wonderful litter.

Rated 5 out of 5 by from The ONLY Litter our Cat will use! Perfect name for the litter product - WORLD'S BEST! Our cat is very particular about her litter and we've tried many, many, different brands over the years. World's Best has won "paws" down. It's the ONLY litter she will use. God forbid if we can't locate it when we need it. When we had three cats it was put to a more rigorous test and passed with flying colors! No oder, no dust, easy to pick up soiled parts and safe for all. It keeps her happy and us happy.

Rated 5 out of 5 by from Love this stuff! I have a two cat household, and one cat passes an enormous amount of urine at a time. World's Best clumps well and minimizes the odor. Will continue to use.

Rated 5 out of 5 by from Wish There Were 10 Stars! We've been using The World's Best Cat Litter for a few years and are really happy with it, after searching and trying many different things over time. Some is too big, some track a LOT and the material feels yucky under foot. Some don't have the best smell out of the bag in order to control the odor kitty puts in there. Once we got to this brand, we were delighted to find it's clumping action and low track-ability changed our lives. Our animals are important, and so are we - so "everyone happy" is a real luxury. No silica - environmentally friendly - and it lasts longer than *every* other we've tried - and that's a LOT. This one, the cat loves, dad loves, kids - me too (I'm the mom). Whenever someone asks "What's a good kitty litter to get?" we always encourage: "Oh - ya HAVE to try the World's Best Cat Litter - because it *is*!"
