Can I dispose of the used litter outside under bushes and trees?

Answer by LydiaApr 25, 2025
no, cat feces has bacteria and parasites that can infect wildlife. Please don't throw this outside

what EXACTLY are the differences in the materials and size (consistency? Size of pellets?) between the multiple cat litter , comfort care, or low tracking? are the pellets different sizes or are there additives to some ?


Does it work in little robot 4 with hopper


Sometimes my one dog gets into the litterbox. If she eats some of it, will it hurt her?

Took to the new litter quickly.

I was told by many people this litter was an excellent choice. I travel the country in a small motorhome and the clay litters were awfull at tracking, plus the dust. I tried synthetic even worse. I tried about every brand with same results. My gal was having continued constipation issues after food and treat changes, all pointed to the clay litter as a possible cause. Her cleaning after using the box was one of the reasons. I looked for a digestible choice. I tried several varieties of litter and had zero satisfaction. NB litter dust is, almost zero, the odar of the litter itself is sort of a sawmill smell, to me. She adjusted to the different texture with no problem. I think it's more gentle on her feet too. When she does her business there is no offensive smells of feces or urine. I still had a major problem with tracking. I bought a bag of OKOCat mini wood pellets and mixed it in. The tracking was reduced by 90%. Now we both are very happy.

The only litter that made my cat stop peeing outside of the litter box!

I have been on the hunt for a new litter for months. I have two cats, one of them all of the sudden started peeing outside the litter box and would not stop. Everyday

I have been on the hunt for a new litter for months. I have two cats, one of them all of the sudden started peeing outside the litter box and would not stop. Everyday I would find another pee puddle. I ruled out any health issues and once I understood it was behavioral, I tried everything to get him to stop. I was using crystal fresh step for years and decided it was time to change up the litter to see if that was the problem. I changed to 2 different types and the problem was still persisting. I finally decided to try World's Best and I was BLOWN AWAY. Not only has my cat Nyx completely stopped peeing outside the box, the smell and the cleaning process improved. The ONLY thing is that it definitely tracks like crazy but I keep it under control with a litter mat and a vacuum. This litter is also WAY better for the environment than the older litter I was using, and I am able to flush it in the toilet perfectly. I would give 5 stars if tracking wasn't an issue, but really love this product, so I'm giving it 4! :)

Dusty, Stinky

Mission: Find the best unscented natural clumping litter. || Other litters tested so far: SmartCat Unscented Clumping Grass Litter || Cat Rating: 4/10, My cats used

Mission: Find the best unscented natural clumping litter. || Other litters tested so far: SmartCat Unscented Clumping Grass Litter || Cat Rating: 4/10, My cats used it right away. However, they seem to be bothered by the dust that clings to their feet..(see dust section). || Clumping: 7/10 Good clumps! There are small pieces here and there, but it’s manageable. || Dust: 2/10, This litter is DUSTY - the second I felt it, I knew this would be a problem. My cats’ feet (black cat and grey cat) are visibly dusted over after using the litter box, enough so that they clean their paws after every use. The times that they don’t clean their feet, our couches are covered in dust when we’ve never had this issue before, even while using clay litter. || Smell: 3/10, The poo smell control is pretty bad, even though I’m scooping twice a day. There’s also quite a strong unpleasant barn-y smell that comes off the pee clumps when they break apart, but is only noticeable when scooping. || Tracking: 4/10, This tracks slightly less than grass litter, I imagine because the individual granules are a little heavier. I still have to sweep at least once a day to keep up. A larger litter catcher mat or a roomba might help. || Value: 4/10, While 26lbs probably would last us the month with two litter boxes and two cats, I’m not sure we’re going to be able to tolerate the smell and dust for long. For the price, I don’t think it’s worth it - I could buy a much cheaper clay litter and have the same experience. || Would I buy this again? No || Avg: 4/10

Very dusty!!! See photos. Company claim of 99.9% dust free is a lie

I bought this expecting less dust than the regular multicat World's Best (red bag) which has become incredibly dusty ( have been using it for years). Well, this is just as bad. I actually measured the amount of dust in the 15 lb. bag by pouring the litter out with a fan blowing on the stream of litter (see photo). I did this multiple times until most (but not all) of the dust seemed to be out of the litter. I scooped up the dust which had accumulated on the concrete of my patio and weighed and measured it. This was NOT all of the dust as some blew further away and some I couldn't scoop out of the seam in the concrete. The result was that I got 1.25 cups (5.4 oz. by weight) of dust from 15 lbs of litter. If you do the math, this is WAAAY more than 0.1% dust from a 15 lb. bag (they claim the litter is 99.9% dust-free). Yes, I was angry enough to waste my time doing this (I was also trying to make the litter less dusty because I needed to fill the litterbox) but I am sick of companies ripping all of us off with false claims and crappy products. Do not buy any World's Best litter until they fix their products and make them perform as advertised.

Cat owner of 40 years- Grateful for trying new litter. Now I won’t ever change

Chewy you are the best for offering great products and your Chewy team that is knowledgeable enough about cat litter to offer suggestions when needed. After health

Chewy you are the best for offering great products and your Chewy team that is knowledgeable enough about cat litter to offer suggestions when needed. After health issues for my family and cats, we researched our home, air and litter dust that settled everywhere unknowingly to us. Dusting, vacuuming and sweeping to keep things really clean didn’t help. We found out it was the clay toxic car litter that we used for years without knowing g the downside to having it in our home. After deep cleaning our carpets, furniture, and home: we ordered a aur filter from Chewy, switched to Worlds best cat litter and never looked back. No more allergies, no more hauling he vet cat litter downstairs and rolling heavy trash cans to the curb, no more cat baths just to keep clay litter off our kitties so they don’t sneeze and lick unhealthy fur. We’ve told our furbaby friends, neighbors and family about the brand and benefits. Switched a lot of cat owners over. Thank you Chewy and Worlds Best cat litter ; you live up to your name , love Coco and Papeika

If you don’t know, clay cat litter can go into your lungs, the same way as asbestos or silica! This clumping corn is the best. I know it’s healthy for me, and I feel confident when I see my kitty licking this corn powder off of this feet. What a good use of corn. I was pleased when he started to use it with no problem. We have a backup jug of clay litter that we have never had to use. I love the corn!!

This is great litter but packing is an issue

Clumps great. Lightweight. Renewable resource. No odors. BUT this is the second time that my bag arrived with a hole in it. Litter all over insude the box. Falling out on the floor as I bring the box inside the house. I realize you are trying to minimize the box or boxes used in shipping. I appreciate the attention to the environment. And please, don't cram it so full that the litter bag gets punctured.

Broken bags!!!

We love this litter and have it on auto ship (5 cats in the house) but since the manufacturer changed the type of bag this is packaged in (much thinner quality),

We love this litter and have it on auto ship (5 cats in the house) but since the manufacturer changed the type of bag this is packaged in (much thinner quality), they are almost always split at the top on both sides resulting in litter spillage. It’s obviously poor quality packaging because every single bag is split at both ends at the top. Not Chewy’s fault but it’s unacceptable when part of the litter is strewn inside the chewy box. It makes me want to spend the extra dollars, go out of my way and shop at a local business instead.

best litter ever!!

This is seriously the BEST litter I’ve ever used. I used clay litter for a long time before deciding to try something new that’s better for my house and my cats

This is seriously the BEST litter I’ve ever used. I used clay litter for a long time before deciding to try something new that’s better for my house and my cats. I even tried crystals and that was worse than the clay litter. However, this corn litter is the best I’ve ever used. It clumps great, it’s very low tracking, and it’s not dusty!! Another bonus is that it doesn’t stick to the bottom of the litter box when my cats use it so it’s very easy to scoop. I will never switch to another litter after using this one. I’ll be giving the remaining clay litter I have away to friends because I will not be needing it anymore.

Disappointingly Dusty

I got this litter because the reviews were great and said it was non-dusty and didn’t have a smell. The morning after switching, our entire black couch was covered

I got this litter because the reviews were great and said it was non-dusty and didn’t have a smell. The morning after switching, our entire black couch was covered in litter dust. That, and our apartment smelled like straight cat poop to the point I thought one of them had an accident. I really wanted to like this litter because I’m trying to avoid the clumping clay, but sadly we will be switching to a new type immediately.
