Questions & Answers

43 Customer Questions

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 the litter itself have a scent

Hi, since this litter is corn based, will it attract mold over time?

Answer by Chewy • Jun 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.

Will this work with automatic cat boxes?

Answer by Chewy • Jan 06, 2018
This Clumping Litter will be suitable for most automatic (sifting/mechanical) litter boxes.

HUGE bag! The listed weight is almost misleading.

I'm so used to using clay cat litter that when I ordered the largest size bag, I was expecting an amount smaller than what we're used to. I was more than pleasantly surprised to find that the bag was bigger than my torso, and the product itself has been working great. It's not as low tracking as I was hoping for, but it definitely tracks a lot less than regular cat litter. It clumps really well and makes cleanup/scooping a lot easier for my husband.

Bug Infestation

We have multiple cats and have used this for years with no issues. I loved it because it did not creating dust and was light. Late fall we had an infestiation

We have multiple cats and have used this for years with no issues. I loved it because it did not creating dust and was light. Late fall we had an infestiation of beetles going after the organic kitty litter for food. Our daughter, who is the vet pathologist, said to get rid of the World's Best and go with a non-organic brand to eliminate the food sources for the beetles. We did and no longer have beetles. It was off that it took several years for this to be a problem

Not sure how to rate this, since I don't think it's a bad product. It's just an issue with how my pets behave with it (and maybe others would like to know about this possibility before getting it). They like it, but not the way they're supposed to... When the cats do end up using the litter, it seems to work perfectly fine. The only problem is, they just want to eat it. Even my dog wants to eat it. I wanted it to work out, but if everyone is going to treat it like a snack I should probably stop buying it... ^^"

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!!

Best balance of qualities for me and my kitty

I used this litter for years with multiple cats. They all liked it but I thought I might be able to do better. I've tried other litters. Some are WAY too heavy

I used this litter for years with multiple cats. They all liked it but I thought I might be able to do better. I've tried other litters. Some are WAY too heavy or don't clump without sticking to the bottom of the litter pan. Dusty, poor odor control etc. Some are better at one thing or another but this one is best all round... especially when taking price into consideration. My cat is happy and I'm satisfied.

Great natural corn based litter.

This is the best cat litter because it's made of corn and won't harm my cats digestive system or teeth/mouth. Those hard clumping cat litter can and has adversely affected my cats digestive system and mouth/teeth. I ONLY USE WORLDS BEST CAT LITTER, because it will be safer than those other hard clumping cat litters. It's about the same price as those inferior litters and I have Chewy send it to me twice per month so I don't even have to lug it home.

Best and safest clumping litter

It's not entirely dust free but it's so much better than alternatives. It doesn't have that awful smell that clay litter does, and it doesn't have the health risks

It's not entirely dust free but it's so much better than alternatives. It doesn't have that awful smell that clay litter does, and it doesn't have the health risks that clay clumping litter does. It has a neutral smell and the clumping is sufficient to track how much my cat pees (he has a history of crystals/blockage). It lasts about a month with zero smell, as long as you scoop every 1-2 days.

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

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.

I decided to try something different, heard great things about this litter. I think it’s a great product and does work and does everything advertised. My issue, I have a black cat. This stuff is dusty, my poor baby comes out of the bathroom all gray. So I would say it’s safe to say, its NOT dust free. Will be going back to the arm and hammer plant base litter, there is absolutely zero dust from that product.
