Style: Clumping Cat Litter Size: 37lb – Frustration Free Pack
So far so good. No dust cloud, good clumping. Fair odor control lasting a long time. I have one cat only. Sometimes another cat might stop by. I try to clean every day.

Style: Clumping Cat Litter Size: 18 lbs
My favorite cat litter. I have two cats. There is never in order in either litter box. No dust at all. I like the clumping action. Makes the litter box much easier to clean.

    • Best Cat Litter EVER! Totally Worth It
Style: Clumping Cat Litter Size: 37lb – Frustration Free Pack
Review Image by Berenika Mocarski Berenika Mocarski
Review Image by Berenika Mocarski Berenika Mocarski
I’ve tried a lot of cat litters, but the Arm & Hammer Clump & Seal Platinum is by far the best. It’s 100% worth the money — I’m never switching to anything else. The litter keeps odors completely under control; my house doesn’t smell like cat waste at all, even after a few days. I love the fine sand texture — not rocks — which makes it comfortable for my cats, easy to scoop, and keeps the clumps tight so it lasts longer. It really covers waste perfectly. Plus, it doesn’t track or stick to paws, so my floors stay clean. Overall, it’s clean, odor-free, and my cats actually seem to prefer it. If you want a litter that works as advertised and makes your life easier, this is it. Definitely get this on subscription since it’s an online exclusive and you don’t wanna be without it!!! ... show more

    • Great odor control and clumping, terrible tracking
Style: Clumping Cat Litter Size: 37lb – Frustration Free Pack
I've been using this litter for the last 5 years, in different living configurations (house with basement, apartments with good litter box spaces, more cramped apartments without). The good: This is consistently a great litter for odor control, even across lots. The clumping occurs quickly, and generally forms easily scooped clumps. The fine grains of the litter are very easy to scoop, and unclumped litter quickly falls through the scoop. The middling: The litter color and quality varies a lot across lots/boxes. Sometimes I will get a box of dark gray litter that creates rock-hard clumps and has basically zero dust. Sometimes I'll receive a box of light gray litter that releases dust clouds when I pour it in the box and forms slightly looser clumps. I'm not sure if this is normal for other litters or if it's unique to this product, since I've stuck with this the longest. The bad: This litter is very lightweight, which makes scooping a breeze, but it tracks EVERYWHERE, especially if you have a medium-long hair cat with paw tufts. This is fine if you have a separate space for litter boxes, like a basement, but it can be a nightmare for small apartments. If you have a robot vacuum and hardwood floors, the vacuum's brush will often fling litter away instead of gathering it for the vacuum to collect, because the granules are so light. ... show more

    • Clumps well, no stink
Style: Clumping Cat Litter Size: 37lb – Frustration Free Pack
This is the best litter we’ve tried for our cats. Clumps really well and absolutely no odor for almost 2 weeks. The key is keeping the litter several inches deep!

    • Minimal dust, small granule size sifts easier, clumps well, doesn't glue itself to the bottom of the litter box
Style: Clumping Cat Litter Size: 40 lbs
I had been using Dr. Elsey litter for a couple of years but it's dusty, comes in a hard to handle 40 pound plastic bag that my cats love to rip open when I'm not looking and you can NEVER get a deal on it anymore. It's 17.49 everywhere - almost like it was price-fixed at the end of 2017 across the board on Amazon, Chewy and Pet Smart. This a review for the Arm and Hammer Clump and Seal so I'll get on with that but you needed to know what changed my mind to use this product and not Dr. Elsey Pro -Very fine consistency, almost like coarse golf course bunker sand. That means it sifts effortlessly which reduces dust because you don't have to shake the litter sifter. -Comes in a cardboard box with a strap handle, NOT a plastic bag like Dr. Elsey. That makes Clump and Seal easier to transport, store, pour and the packaging is cat proof. I have to leave the Dr. Elsey litter in the Amazon shipping boxes to cat-proof them in my house. If you take the Dr. Elsey litter out of the box, it looks like you're storing sand bags and the 40 pound bags are really hard for my wife to handle -Clumps well and doesn't "epoxy" itself to the bottom of the litter box like Dr. Elsey litter. -The "tracking" of the litter by my cats outside the litter box has dropped 75% since I changed from Dr. Elsey litter. The Dr. Elsey litter turns to glue when it gets remotely damp and it sticks to the cats feet, the Arm and Hammer does not hence the great reduction in litter outside the box -Cleans up far easier than Dr. Elsey. When it's time to change and was wash the litter box, the finer granules of the Arm and Hammer product are easier to remove from the litter box and they don't glue to the box when damp like the Dr. Elesy product -I can go three weeks between litter box washing. I clean daily (2 cats) and add new litter as needed but the Arm and Hammer product does not smell at all after 2 weeks. That fact makes the Arm and Hammer product cheaper than Dr. Elsey. Con (not really "cons", more like observations about other customers "cons") -Many of the 1 star reviews are about the odor of this litter. It has an odor but it's not bad. It's better than the smell of cat crap. But if you are odor intolerant, you might not like this product but it doesn't bother me -Clump and Seal appears pricey. I only buy it when I can get a coupon deal because $24.99 IS pricey. Knock off $2 and add in the fact that you can use less of this product than Dr. Elsey due to the smaller granule size and it's about the same price as the now "price-fixed" Dr. Elsey litter. In summary, I'll continue to use Clump and Seal based on my feature/benefit summary above. Your experience may vary. Happy litter box cleaning. ... show more

    • Great litter for the Litter Robot 4
Style: Clumping Cat Litter Size: 27.5 lbs
The go-to litter for my Litter Robot 4. It is low dust and great clumping. The cats do not track it much either. I have pet mat spread out in the cat room in front of the litter robot and the litter does not track to other areas of the house. It has made our life so much easier in a multi-cat household. The box is also very well designed which makes opening and pouring the litter very convenient. ... show more

    • Not all of these are the same. Some are not good. Stick with the platinums
Style: Clumping Cat Litter Size: 18 lbs
Do not buy the Clump and Seal that is not the platinum! It stinks worse. This one worked. I still prefer the slide option best, but this has been really good.
