Rated 5 out of 5 by from The best cat litter I've used in years I work in the administrative offices at a local animal shelter, and we have five hospice/senior cats living in our office space. Because we're a nonprofit, we typically receive donations of kitty litter from the public or local pet/food stores, rather than buying our own - so we use what we've got on hand. One time, we received a bag of World's Best Cat Litter, and it was brought up to the admin offices for us to use. It is, by far, the BEST clumping cat litter I've ever used -- I even buy it now at home. Boy, does it CLUMP. It's easy to clean; there's virtually no smell; it produces little to no clouds of dust (to be honest, I haven't noticed any); and it lasts for weeks. If you're hesitant about trying this product, for whatever reason, don't be: I HIGHLY recommend it for any cat owner, even those with kitties who tend to be picky about their litter. Even better, it's eco- and pet-friendly. Worth every penny!

Rated 5 out of 5 by from LOVE this cat litter, SO easy to use I am so happy to have found this litter. It REALLY clumps, and stays clumped when you remove it. Not like the clay litter that smells over time or needs to be dumped often. There is no smell. I just scoop out what has been clumped and refill with more litter when I need to. Never have to change it like other litters. I have 1 cat the suffers UTI issues and this litter has been a life saver. As I need to make sure he's peeing enough, getting enough water. The clump alone tells me yes or no.

Rated 5 out of 5 by from IT IS TRULY THE BEST LITTER I never write reviews so it must be special. Living in a small NYC apartment I was not happy with the smell of a litter box. I clean out the clumps every morning but there was always a lingering smell if you got close to it. My Gus is fussy and I have been afraid to switch from his usual Tidy Cat. Well...he didn't fuss about the new litter and I couldn't be happier. There is absolutely no smell, the liquids clump very well and it can be flushed down the toilet. Thank you for making a great cat litter and although it is expensive it is going to last a long time. So worth the peace of mind.

Rated 5 out of 5 by from Reviewed by my kitty Absinthe Just wanted to express a big THANK YOU for having a superior product. My little gray girl Absinthe was adopted from Pet Smart along with recommendations for her litter and food. I first purchased your product on the day I took her home. A few weeks ago I was at Cosco and decided to try to save a few pennies and purchased A & H Clump & Seal. Upon opening the huge box, I left the room for a few moments. As I walked back in the room, I saw my kitty in a frenzy. She was sitting atop the box trying to scoop out this horrific smelling litter. What was I thinking pouring it into her pan? At first I thought she was playing, but realized it was offending her senses 100 times more than it was affending mine. I began to get a headache, so imagine what my little ball of fur was going through! The next day I was back at the store to purchase WBKL. I called Arm & Hammer and gave them an earful. So the evil, horrible, unhealhy A&H Clump & Seal is now in the utility shed to blot oil from the lawn mower. The stuff is so foul it will probably chase the field mice away. I had to share Absinthe's 'happily ever after litter' story.

Rated 5 out of 5 by from No Smell!! I tried this litter when it first showed up on the market and liked it but haven't gone back due to the cost. I recently splurged on a large bag and I'm so glad I did. This stuff is amazing. There's no dust, it clumps amazingly, easy to scoop, and there's practically no odor. It's simply wonderful.

Rated 5 out of 5 by from I'm a total convert... ...and so is Josette (my cat)! So many great things about this litter..green clean, no scent, does what it purports to do (how refreshing is that) and, perhaps most importantly, my cat loves it. Can't get much better than that!

Rated 5 out of 5 by from That's why it's called World's Best. Cat litter isn't something to write home to mom about; however since we moved to it, I truly can say, you have earned the name.
