What is the difference in the sccopable and the clumping formulas?
Answer by ChewyJul 09, 2017
The Clumping Formula (in the bright green bag) has good odor control and forms tight clumps. It is ideal for 1-2 cats. The Multiple Cat formula (in the red bag) is just like the Clumping Formula but has additional all-natural plant material for enhanced odor control to stand up to mutiple-cat homes.

Will this work with automatic cat boxes?
Answer by ChewyJan 06, 2018
This Clumping Litter will be suitable for most automatic (sifting/mechanical) litter boxes.

Hi, since this litter is corn based, will it attract mold over time?
Answer by ChewyJun 14, 2018
Corn-based litter are processed to eliminate the moisture necessary for the fungus (Aspergillus flavus) that produces aflatoxins. In a home environment, it needs to be kept in a dry location and the box scooped frequently so that no moisture gathers.

What is the difference between multi cat and normal litter
Answer by ChewyOct 27, 2017
The World's Best Cat Litter Clumping Formula is ideal for homes with one or two cats. The World's Best Cat Litter Scoopable Multiple Cat Clumping Formula has an additional added all-natural plant derivative for enhanced odor control and is ideal for homes with two or more cats.

Not living up to hype, comparing to tidy cats unscented

Pros and cons of this litter PROS: - flushable, very convienient - does seem to be lasting longer than other litters - tracks significantly less, seeing a lot less litter throughout my place. It seems like tidy cats would get stuck to the bottom of their paws and would fall off as they walked and track throughout my apartment. This barely tracks outside of the bathroom where their litter box is which is a huge plus. Honestly it seems like the "tracking" is just when they accidentally kicked some out or get the zoomies and sprint out of the litter box. CONS - i dont know who's saying it doesn't have a scent. it absolutely does as it comes out of the bag and it smells weird, can't put my finger on what but I don't like it. Tidy cats unscented had 0 scent and was so neutral. - It does not completely mask the urine smell. I clean my litter between every day and every other day. If i wait a day in between a bad smell fuses between the cat pee + weird smell of the litter. never had this kind of issue with tidy cats. - absolutely not "dust free" If you have black cats you'll see this on their paws. I stuck my hand in this when i first got it and a film of sawdust like material covered my hand. i know this is natural and made from corn, but i don't know how they chemically processed this and makes me uncomfortable that my cats are licking the dust off their paws when they clean

The smell will haunt you

This litter could be purrfect if it didn’t have such a strange and powerful smell. I gave it a good try for a few months because I wanted to like it but I HATE IT. It definitely has a smell that starts kind of neutral-spicy then as it is used turns to disgusting-spicy and it lingers like a poltergeist just beyond the veil, forever clinging to this litter. It is not a normal litter smell, it is entirely new and vile and never have I ever smelled anything like it and I hope never to again. It clumps well and is low dust, but the smell is unforgivable.

I never do this. But I just have to say it really lives up to the name. NO odor, except a mild, almost straw-like odor. CLUMPS amazingly well. CATS took to it, well like a cat in nip. ALMOST ELIMINATED LITTER SCATTER. I mean, I had litter going all the way up my basement stairs into the hallway. Now? Almost nothing. A simple sweep once or twice a week in the immediate area is all it takes. I'm absolutely THRILLED!

It really is the best

I've been using World's Best Cat Litter for years on the recommendation of a friend. Last month I switched to a store brand then to a name brand cheaper litter. Never again. World's Best really is the best. I don't know how they do it, but even with multiple cats, there is no smell, waste clumps so cleanup is incredibly easy. I'm sorry I strayed on you World's Best. It won't happen again.

Great Litter

I have two adult cats and have gone through quite a few different brands. This brand has worked the best by far out out of all the others I have tried. It lasts long and keeps the stink down as long as you clean it so often. Also love the fact that it is a more natural based cat litter.

definitely worth it

this is my new best friend. i have 3 kitties, one who pees like niagara falls. my main problem with him was the smell of ammonia urine ALL. THE. TIME. with this?? it instantly sucks it up into a solid, scentless clump. i love it!!! major caveat of this one: needs daily cleaning or it doesn't work well. but worth the extra effort to ensure my house doesn't stink!!

I really wanted to like this but....

...our cats did not. On paper (and if you're cats like it), it's a great product. Flushable, great for the environment. But the cats preferred the Tidy Cats litter they're use to. We tried slowly converting them with a mix in one box but they would avoid the box and when we tried to convert the other boxes, they protested and went elsewhere. We plan to keep 1 box with this litter until we're done (unfortunately, I was overly optimistic and purchased 2 large bags). Also, it doesn't do a great job keeping in odors. We clean our litter boxes at least once a day and since, this is flushable, I would do that particular box more but I'd still smell the lingering pee scent.

Tried & True through multiple generations of cats

I have 3 cats and always have, so there have been quite a few who have been happy with this litter over the 15 or more years I have used it. It clumps very quickly, is scoop-able and flushable. I scoop 4 times a day and still, a bag lasts for quite a while (a good thing given how pricey it is). From kittens to much older cats, I have had 100% acceptance. If you have more than 1 cat, do use the multi-cat formula. If switching litters on your cats, always transition by the book. They are creatures of habit to the extreme. Transitioning properly, as with a change in food, is critical to success.

World’s Best Cat Litter

This truly is the best litter money can buy! There is no dust, clumps quickly, and the grains the kitty may carry out of the box are so easy to clean up. It last a long too, as I clean my cats litter almost every time she uses it. I can add to it, and it never smells. Of course I clean and put new litter in when it is needed.

best cat litter for my cat

I have a cat I adopted that has a head tilt. I’ve used clay littler before but I noticed he’d sniff hard and get it stuck in is nose then he’d cough real bad. So we switched to this and he has zero issues with little. Definitely my fav. I’ve tried at least 4 others before that.
