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

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

Does it work in little robot 4 with hopper

Ok for kittens

The litter bag is supposed be vaccume sealed. However, they are delivered without vaccume seal. Is it bad to use?

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), 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.

Absolutely loooove this litter. I did the change gradually, with each cleaning adding more of the new stuff in. I have 3 cats and have not noticed any odors, it's also very low dust and tracks about the same as my old clay litter. I was having a lot of trouble with the clay litter clumping because sometimes each cat chooses to pee in the same spot, which doesn't give the clay time to properly clump. This new litter is a little more lightweight, it clumps beautifully and it's so much easier overall. I wish I found this stuff sooner!!

No sticky mess.

I have used this litter now for a few months. I will never go back to the heavy, high clay content of the clumping litters. Worlds Best does not stick to everything

I have used this litter now for a few months. I will never go back to the heavy, high clay content of the clumping litters. Worlds Best does not stick to everything. It's really easy to clean. I have a stainless steel litter box and an automatic scooping litter box. This litter works great in both. I find I scoop more often because of it's easier. The wet litter forms a small clump that doesn't expand out forming bigger stickier clumps. It doesn't stick to the litter box or your scoop. This really is a great product and I definitely recommend it for anyone who is tired of the sticky nasty mess.

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.

Our cats loved it for years but something changed. It became a lot more dusty and I was afraid to change because our elderly girl was prone to accidents. Then just recently I discovered that mice like to eat it!!! There was always mouse droppings near the boxes and the traps never caught them. When our cats passed away recently (they were both very sick and old) I caught two fat mice in traps after the litter boxes were removed. I’m going to try a different type of litter for the next cat when we find one to adopt after a suitable mourning period. I just wanted to tell people that might have mouse issues. Thank you to Chewy for being a great resource for our cats.

We’ve been using this litter for quite some time now. We originally started with the clay, but I have a lung disease and did not want to hurt my fur babies with the same thing. So I switched to this brand made with corn, and I really like it. The only trouble I have is that I have a dog that wants to go eat it when he gets the chance unsupervised! And also, many times the clumps of urine will break apart and then it’s not as easy to scoop as it should be. I definitely prefer this over the clay though!! I may explore different options at some point, but as long as kitties are happy with it, I am happy too.

Flush ability.

I like this litter it cleans up nice and the boys like it. Was easy to transition too. I will be switching my other litter box to it as soon as I am out of the gel

I like this litter it cleans up nice and the boys like it. Was easy to transition too. I will be switching my other litter box to it as soon as I am out of the gel crystals I’ve been using. My only thing isit does not handle odor as well as the crystals and is a little dusty, but the cats don’t seem to have a problem with it as opposed to unknown dust that is in the crystals. At least I know this is natural.

It’s true to the description of brand, I have been using it now for since 2011, when I adopted my Kitty at 8weeks old. I use it, knowing it’s not harmful to her respiratory system Prevents smells, and I always clean the litter boxes at least twice a day. I use two litter boxes for one cat. One in the enclosed patio, and one inside my bedroom Changing the litter completely every month She’s is very clean and tidy

It's called world's best for a reason.

I've been using this litter for probably decades or at least as long as it's been on the market. It's so much lighter weight than clay litter and almost no dust

I've been using this litter for probably decades or at least as long as it's been on the market. It's so much lighter weight than clay litter and almost no dust at all. The cats seem to really like it too. I just got a couple new kittens and I gave them a choice between world's best and the litter that they had been using which was a pellet litter made of pine. The kittens stopped using the pine litter and started using the world's best.

This is the best straight forward litter I have used thus far. It does exactly what it says and nothing extra. My cats seem to approve due to the unscented, size and texture of the litter. AND I would mix this with paper or wood chip litter to entice kitties to use a environmental solution as well.
