How bad does this litter track?
Answer by ChewyMar 28, 2018
This quick clumping cat litter provides maximum odor control while minimizing dust and tracking around your home.

Does this contain pesticides?
Answer by ChewyMar 08, 2018
Per the manufacturer, pesticides may or may not have been used by each individual farmer when growing the corn. As each farmer's techniques vary, the answer will vary as well.

Is this a litter a cat might eat? I've had one type of litter that one of my cats was eating because of the corn in it. I don't want that to happen again since she literally would jump in the box and eat it (regardless if the box was clean or dirty). Thank you.
Answer by ChewyApr 23, 2019
Typically, when a cat begins to eat kitty litter, it's due to a health condition. Cats with vitamin or mineral deficiency may also begin eating kitty litter. We urge you to speak with your vet to ensure the cat is healthy.

the bag said it last for 60 day for one bag, does that mean you only change the litter once a month (if you used half the bag)?f it only change once a month that litter would be too "dirty", if it change every 2 week, one bag will not last 60 days even for one cat household.
Answer by ChewyJun 26, 2019
Typically, the 7-lb bag should last approximately 30 days for one cat, the 14-lb bag should last about 30 days for two cats, and the 28-lb bag should last about 60 days for two cats. How often you need to change your cat litter depends on how many cats you have and how often they use the litter box. World’s Best Cat Litter harnesses the concentrated power of corn for long-lasting performance, and pet parents report that they don’t have to change the litter as often as with other cat litters.

it used to be good

If you’re reading this review, you’re probably considering in getting it for your precious fur. You want the best for you and them, and heck. Why say no to a litter that comes from corn and is “the worlds best litter” Well, let me tell ya. This litter used to be good. One of the best ones there could ever be. What I LOVED the most was the no tracking, it was awesome. Up until a month ago. Jeez. When I tell you… my cat, Socks, leaves a trace behind where he walks after taking a leak or a dump!! There’s cat LITTER EVERYWHERE IN OUR HOUSE!! I had to vacuum about 2-3 times this week because it was just everywhere. He’s a tux cat, his back paws and his face would be covered in a light white dust. It seemed like he went partying during the day without leaving the house -iykwim- They, sadly, probably changed their formula and that’s why it changed. I wonder if anyone else has the same problems. But with that, here’s my recommendation: If you want to get it because it “leaves no trace behind”, don’t. If you want to get it because it’s natural and no bad chemicals for you and your cat, do get it. But keep in mind, it will give you a hard time keeping your house dust free. *mic drop*

NOT flushable

No no no no no. No cat litter is flushable and it's irresponsible to say so. Stop telling people to potentially dump toxoplasmosis into the water table! Fwiw, I did use this once to compare to Earth's Finest (RIP) and it didn't. Earth's Finest never smelled like cat urine once scooped, I actually got to use every last speck of litter. This stuff smelled by the end of the week, even with religious scooping, so whatever litter was unused in the boxes at the end of the week had to be thrown away, unused. The other stuff may have been slightly more expensive, but there was no waste like there was with this stuff. Nature's Miracle corn litter is the closest I've found to Earth's Finest. Not quite as good, but it's as close as I could get so I guess it'll have to do. But please stop flushing cat litter, regardless of what the package says.

Stinky. 0/10

On our quest for a decent litter that wouldn't hurt our cat when he cleaned litter bits out of his toes, we suffered through this. Your home will smell like corn and cat pee, and then your cat's powdery paws will track that smell onto all the fabric in your home. Nightmare. We ended up choosing grass litter next, and that is a FANTASTIC alternative for folks who wanted something like the corn litter.

Very dusty

I have been using this litter for over a year now. I love that it is flushable and that it is natural and does not have silica dust. What I have an issue with, is how much dust accumulates as a result of this litter. Every single dust free formula ends up costing furniture with dust in my experience. But my poor black cat just gets covered from face to tail in dust when she does her business. She likes to dig a lot, which probably compounds the issue. But I am left wondering what other litters I can try next.

More dusty than usual

What I liked about the world’s best litter is that it’s very light, it doesn’t smell, and it’s also very granular. This time the product was more dusty and smelly. Have to try other options

Best We've Used

After our many trials this is the one we settled on. Least dusty, not tracked around house so much, cats like it and scoops well. It's not scented so scented ones might even cover up odors better but this does a pretty good job of it.

Almost perfect

My cat had no problem using this new litter. Very absorbent & controls odor well. This litter really cut down on dust & tracking litter outside the box. Does not clump quite as well as other litters, but definitely worth using

I tried so hard to like it...

I bought this litter because it's one of the recommended brands for my Luuup sifting litter box. On paper it sounds great. And it does work better with the sifter than my old clay litter. But it is SO messy! I have a black cat, and he's constantly covered in orange powder from this litter, even on his face. He tracks orange dust everywhere he goes after using the litter box. He'll hop up on my lap and leave orange pawprints on my pants. I guess it's okay with odors, but not any better than the cheaper litter I used before. Despite all of that, I'm on my second bag, because I really wanted it to work. The other recommended option for Luuup is crystal litter like Pretty Litter which is more expensive.

This litter is Dusty af

Is this litter great bc it clumps and you can flush it? Sure. But a lot of litters provide that benefit. I have black countertops and it coats everything. I wonder now what else its all over that I just can't see. I don't remember it ever being this dusty when I used it years ago. Probably changed their formula or something. Onto the next brand...

World's Best Cat Litter

I absolutely love this cat litter!! You are never surrounded by a dust cloud and the litter seems more natural than other cat litters I have tried in the past. The best part about this litter is you don't have to refill as often!! By far the best on the current market.
