Really is "dust free."
By Luna on Jan 23, 2021
I purchased this litter only because it is advertised as 100% dust free. This turned out to be true. It is also easy to clean, and I notice less tracking. I am still transitioning my cats to it, but that has been a breeze so far. The reason I am only giving it four stars is because there is no dust free version of this particular litter that is also scent free. After many years of cat experience (both at home and at a rescue), I believe cats prefer no scent. What I have decided to do is mix this litter with my old litter. My old litter is scent free, so it will tamp down most of the scent in this litter. This litter will tamp down the dust in the old litter.

best cat litter!
By Steph on Jan 22, 2021
We have had 2-3 cats at a time over the years and this litter has never failed to do it’s job- provide solid clumping without the smell that can happen with litter. We use this in two litter robots and it works magnificently. Every six months or so we run out and didn’t have the hindsight to reorder and we always regret the cheap alternative litter we buy. These other litters end up smelling within a few days and I have to empty out the whole litter robot. With the multi-cat Arm & Hammer, we just have to keep topping off the litter robots but never dump all of the litter. Definitely worth the added expense than cheaper clump and seal options.

Best Ever Litter
By emmabliss57 on Jan 10, 2021
Admittedly I did not like the scent at first but I got over it because it is THE best litter ever. Almost no dust. Almost no tracking. Really easy to clean litter which is not true of other clumping litters that create concrete! It does cover the smell pretty well but I’m also super on top of it since we have 5 cats. Litter boxes are cleaned at least once a say and usually twice. Anyone who is trying to get away with cleaning a litter box even for one cat less than once a day is lazy and isn’t being a good cat parent. I don’t know why anyone would NEED 7 day odor control. The more often you clean the litter the easier it is I have had cats my whole life. I know litter. This is the best.

Best I've used so far
By Catowner on Jan 21, 2021
I have two cats so far I've tried Fresh step, "The World's Best Cat liter" and Clump & Seal. With fresh step they tracked it all over and the dust was too much. The Worlds Best Cat liter was awful. My cats always use a liter box and they wouldn't go in it. They actually went beside the box to avoid it. The one time they did use it it had an awful smell. Clump and Seal has by far been the best. Clumps well, low odor, and I haven't noticed hardly any tracking or dust clouds.

Not happy looking for new litter
By Kimme1 on Jan 8, 2021
I loved the cat litter I had been using for years. Also made by Arm & Hammer no dust/ light weight and darker litter color and affordable It was discontinued and the replacement or new close to it .... it’s off white shows everywhere the cat walks and ends up in the bed with you or all over the floor. This product Is what I’m using only until I find it’s replacement. Once the cat “tinkles” the litter becomes SO HEAVY that it broke my scope and the box itself is very heavy, litter/dust from pouring produces a cloud and yet it’s suppose to be dust free.

Way Too Heavy
By Cece on Jan 18, 2021
The Arm and Hammer Lightweight Multi-cat Litter (which was great) that I have been using is no longer available so I tried this. It is heavy enough to give you a hernia when lifting the box. Almost impossible to maneuver and pour into litter box. Quite a struggle. Also, does not smell as good as the one I was using. I’m going to try the Tidy Cat lightweight which my daughter uses for her cats.

Not reccomended
By Sarah on Dec 28, 2020
I have always purchased arm and hammer litter as they have the best defense against foul odor's. However, my cats do NOT like this litter. This litter is not absorbent and the cat waste sits on top of it. Which in turn means my cats are touching their own waste which is not as fun for them as it sounds. They also do not like how it feels on their feet. Even as I scoop up their waste the litter is as hard as a rock. The clumping portion of the litter works infrequently as some times it clumps and is easy to scoop, other times it breaks the second I try to scoop it up.

Clump and Seal what?
By LizfromABQ on Dec 17, 2020
This litter does not clump, is not absorbent, and doesn't seal anything. I spend twice as much time cleaning the litter boxes because the kitty urine and poo are STUCK to the boxes. The kitties are doing their business outside the boxes because their litter box is disgusting and I don't blame them - but I'm not happy. I'm going to try the "Platinum Slide" next because Arm and Hammer discontinued the "Lightweight and Clump & Seal" litter and I'm wondering why, because it was the perfect litter! This "Lightweight Clump & Seal" litter was great, but now I'm thinking they may have discontinued it because it's harmful to animals?

Because Arm & Hammer slide out of stock went back to clump & seal
By Kathy on Dec 27, 2020
And happy I did. I had switched to slide from clump & seal which I was happy with but thought slide would be better because of the name “slide” and have been using for quite a while. When slide was out of stock I had to return to clump & seal I’m more than happy, it seems to be finer, less tracking, better clumping than slide. Chewy has the best service and cares about its customers! Thank you, Kevin & Buffy’s Mom!

Best litter ever.
By RTHatchet on Jan 1, 2021
I can stick it in there, forget I have cats too. To the point to where, since I work so hard, sometimes it won't be cleaned a week. (I have HUGE litter boxes, 1 box fills 2) When I clean it out, I literally get 10 inch long, 5 pound clumps. Best clumping litter there is. Has no smell. Hypoallergenic for me. Not dusty in the least bit when cleaning. Perfect for multiple cats (it's recommended to have 1 litter box per cat. I've NEVER had a cat use the bathroom in my house ANYWHERE)
