Looked pretty

[This review was collected as part of a promotion.] I started using these before using pretty litter and even though I sprinkled them all on top- they didn’t change color or even absorb anything. They don’t give you enough to test clumping ability bc he needed to actually have enough to pee on.

10/10

[This review was collected as part of a promotion.] This stuff Is absolutely amazing. It clumps nicely low dust level. The absorption is great but the best part is it told me that my poor cat had a UTI and I would have never known otherwise thanks to that letter

Lives up to the name!

At the Charleston Animal Society, we proudly use World’s Best Cat Litter because it truly lives up to its name. It's made from natural, whole-kernel corn, making it not only safe for cats but also environmentally friendly and flushable. Its superior clumping ability and outstanding odor control make cleanup quick and easy, which is essential when caring for multiple cats. The low-dust formula helps keep our air clean and our cats healthy, especially those with respiratory sensitivities. After trying many brands over the years, we've found that World’s Best Cat Litter offers the perfect balance of performance, safety, and sustainability—making it the clear choice for our shelter and the cats we care for.

AMAZING

I’ve adopted 2 kitties from Fur Babies Cat Cafe partnered with Carroll County Animal Shelter in GA, and we LOVE this litter!!! The cat cafe barely smelled, and all the kitties seemed to enjoy using it, so now we use it at home too & will never go back to clay!

Clay out, Corn In!

My cat loves this litter! Bought it because it's not clay and my cat has had no issues! The scent is natural and doesn't burn my nose. It doesn't smell too bad when it's been used, either!

Okay

[This review was collected as part of a promotion.] I received a small bag and tried in a litter box and it didn't have anything happen or odor control. So I don't know what is it exactly use for but tracking your cat health

Don’t work

[This review was collected as part of a promotion.] This wasn’t actually cat litter it’s a small bag that you add to the cat litter to check if you cat had any health issues. It didn’t work for me unfortunately

Useful and fast

[This review was collected as part of a promotion.] Our cat is very important to us but it’s hard with two kids to stay on top of every behavior to make sure he’s totally healthy. This genius product helped us check his health in minute and gave us peace of mind between vet appointments!

Cat health knowledge from home

[This review was collected as part of a promotion.] This product is informative of your cats urine health with an easy reader to understand what each color represents. It mixes in easily with normal pebble litter but not so well if you use shredded paper for your cats kitty litter.

10/10 recommend!

[This review was collected as part of a promotion.] My cats loved this it helped them so much I am really thinking about buying this item because it has been very good to them. It doesn’t smell and it wasn’t messy. I was able to know if they had anything wrong with them and it absorbed very quickly.

Cat litter additive

[This review was collected as part of a promotion.] I never received this product in the mail but I did end up purchasing it myself because my cat was having some issues using the litter box. It detected her PH was off and had a UTI. Im relieved to have this product. It didn’t have a bad scent or prevent use. It’s an easy additive to use and I had no issues with it affecting the litter, clumping or causing dust.

Would repurchase!

[This review was collected as part of a promotion.] This cat litter got the job done. It was very absorbent and easy to clean up. I didn’t notice a scent while using this. I would definitely repurchase.

Unable to try

[This review was collected as part of a promotion.] World best cat litter may be the best but considering I never received it I can’t tell you that. Sorry I’m sure the odor is pleasant. I’m sure it doesn’t clump. I’m sure it absorbs great too. Who knows?
