I've been using unscented World's Best for my cats for over five years, and hope this product remains on the market for the duration. It weighs less and is much easier to clean than clay-based or pine-pellet litters, and remains odorless. Wet litter clumps and scoops easily, leaving the dry, unused litter in the box for later use. Lasts longer, is corn-based (no strip-mining, biodegradable), and has a soft texture my cats like.

I have been using this brand for the 20 years and the cats don't seem to mind it. I used it when I had a cat that was allergic to everything and she had no problems with it. As long as the cats keep using the uncented litter I will continue with it I love that it clumps when wet and is easy to remove from litter box.

I have always bought the red bag for multiple cats and loved it. My husband couldn't find it so he bought the comfort green bag and although I still love this brand I don't think this one clumps well at all

I bought this thinking it would be a better alternative to the previous flushable litter we were using. I was wrong. White the last one has large pellets that occasionally got stuck in my cats paws, this one is so dusty I can go out for the day and know exactly where my cat has been by tracking her paw prints. Would not recommend, I'll be looking for a better alternative.
