Is this reallt flushable? Does anyone flush it daily? I have 3 cats and scoop at least twice daily, and would love to be able to flush it, but am afrid of it clogging the toilet.
Answer by ChewyFeb 27, 2018
This litter is flushable and biodegradable.

What is the literal difference between the ingredients in Zero Mess and your regular green bag litter? Are all ingredients safely consumable?
Answer by ChewyJul 24, 2019
The ingredients in this litter are corn and plant fibers while World's Best Cat Litter Clumping Formula only contains corn. This litter is not meant to be consumed.

What is the difference between the zero mess and the standard litter?
Answer by ChewyMay 02, 2019
Zero Mess is part of World's Best Cat Litter's Advanced Series, which delivers long-lasting litters purpose-built to solve specific problems. The Original Series offers long-lasting litters with outstanding overall performance.

How long does each size bag last for one cat ?
Answer by ChewyDec 31, 2018
The longevity of the bag depends on how often your cat uses their litter box. It's recommended to scoop out waste twice daily and refill box as necessary, as well as replace the entire box once a month.

Not Quite Zero Mess

"Zero mess" is obviously a VERY high bar for a cat litter to set for itself and I wish I could say "but this litter does it!" But it doesn't. There's a lot of dust, and my cat manages to get it all over the walls of the box and then himself – he's all black, so it's VERY apparent when he's covered in litter dust! Still, I like World's Best as a brand, way easier to clean than clay-based litters.

Ehhhh I'm not buying again

The odor control is not terrible. The bag, however did not last me the advertised 75 days which makes it a pretty expensive litter option for a multicat home. Bag lasted me about a month. It clumped ok. Kitties get it stuck to their paws a fair bit- I've found some litter in my bed which isn't super Kash Money.

This is 99% dust free? Then I'd hate to see the 98% formula!

The good: it clumps reasonably well, though not as good as the clay litter I was using before. And being flushable is nice, since I have my litter box in my bathroom. It is also quite lightweight. The bad: The DUST!! Everything in my apartment is now coated in corn-based powder. Also, I never noticed any smells from my litter box before, but now I do. Pee odors seem to be neutralized, but poo is not, even when my cats try to bury it under a mountain! And I have gone through more Febreze in 6 weeks than I have used in 6 years! Based on other reviews, I might give their "red" bag a try. Because I would like to be able to flush my cat's waste. But I'd rather whatever minor inconveniences result from heavy clay litter, than having to deal with all this dust.

Worlds Best?

It is so light it gets tracked out of the box more, no solid clumps.

Excellent Litter

This is the best cat litter I have found. It controls odor, stays dry and odor free longer, and doesn’t have to be dumped out and refilled as often as most litters. Even though it costs more per pound than the others it lasts a lot longer, and takes less work, so it’s worth it.

Has WB actually used this litter?

World's Best is a stretch, as this is the dustiest litter we've used so far, the cats track it everywhere, and odor control on poop is limited after a couple of days in the box! I do love that it is corn based but never buying again.

Turns to dust

Thought I'd give this a try but it quickly turned to dust in the litter box I only use world's best litter and the Orange bag works the best not this I have 2 cats and super giant litter boxes and was not impressed with this kind

Not as good as other litters by worlds best

I have long haired cats and it really stuck to their pants and had to be brushed out. I went back to the lavender corn litter. Only thing about that is it’s dusty but still a great product.

Turns to dust

I love this brand but the formula for this one I really dislike. It turns to a fine dust after a few days which my cats track through the house. Stick with their regular product.

Not as good as WB’s other products

5 litter boxes for 3 cats. We prefer World’s Best’s other products, but this is still better than any other litter brand on the market. We’re huge fans of the other WB litters but for us, this version did the opposite of what was intended. My cats made more of a mess, tracking litter 3-4 feet from the boxes. Plus it didn’t absorb or clump as quickly as other WB litters. The one bright spot: our one crazy cat who LOVES a newly cleaned and changed box so much that he’ll lie in it for 5 minutes and play and fling the fresh litter all around himself — well he didn’t feel moved to do it with this product. A nice surprise, but not nice enough. :D
