Why is my Arm & Hammer Clump & Seal Litter making larger, heavier clumps than it used to?

Does this have silica in it?

Do you guys have a smaller (lighter) size box of Arm and Hammer Clump and Seal cat litter? If not, will you be able to get some? it's sooo heavy! :( Thanks, Lynn

I'm pretty new to the clumping litter. I continually scoop out my kitty's business, sometimes within minutes of her using it. My question is how often do you need to empty the litter box to clean and refill with new litter.

Answer by Chewy • Apr 07, 2018
We recommend totally changing the litter out in the cat box every three to four weeks depending on use. Wash your cat boxes with hot water and a mild detergent like Ivory dish soap and then replace with about 3 inches of new litter

No DUST period !!

Hands down, in my opinion, this litter is by far the best. There is literally no dust at all. I had a brand B4 and the entire area was always covered in a light gray dust - but not this brand. Plus it is more like sand, which my cats love. I actually bought 4 different types of litter and set them all up and two were completely ignored, other was occasionally used, but this one was the clear choice and winner. It clumps tight and once fully dries does not break apart. Every 3 or 4 days I sprinkle in a thin layer of fresh litter to help boost odor control. It does a great job of keeping odor down and with 6 cats that is definitely a plus!! I always recommend this litter to anyone who has cats and they often thank me because they love it as much as I do !

Smells great!

I am a really big fan of the scent of this cat litter. It gives it a kind of clean scent that reminds me a bit of laundry day! Also, not too much dust when scooping and refilling. My cat also doesn’t track much, if any, of this litter through my house. I let him on my bed with no worries of litter getting all over my bed. Truly love it!

Great Stuff: No Dust, No Litter Trail

We returned to A&H Clump and Seal after trying A&H's newer AbsorbX formulation. The regular Clump & Seal works great. No dust, and our 2 cats track very little

We returned to A&H Clump and Seal after trying A&H's newer AbsorbX formulation. The regular Clump & Seal works great. No dust, and our 2 cats track very little out of the litter pan. The AbsorbX was very light, but the price for that lightness was a daily trail of litter throughout the house and on our clothes after the cats would sit in our laps. Regular Clump & Seal is heavier; scooping feels like sifting through beach sand. That's fine, because the litter stays in the pan, not on us and our floors. We'll happily stick with regular Clump & Seal.

I love the clumping aspect of this litter and we’ve been auto ordering for a little while now. One of my cats has a hard time remembering to cover after going to the bathroom so the scent stays in the air a while.

Meh, not the greatest

I was excited that they claim 100% dust free and the "clump & seal" to reduce odor. I have this box in our large master bath and our 4 week old kitten (only cat)

I was excited that they claim 100% dust free and the "clump & seal" to reduce odor. I have this box in our large master bath and our 4 week old kitten (only cat) makes tiny poops twice a day and this does nothing to "seal" in the odor and is very, very perfume-y so it smells like roadside bathroom deodorizer and poo, which is very unpleasant. The perfume smell is overwhelming even when the box is clean, so much so that I'm almost tempted to move myself to the guest bathroom to get ready in the mornings. The clumps hold together pretty well, but like all other scoopable litter, this ends up all over the place. The litter box is in the bathtub and previously I'd just fill it with water to let the wayward granules that have been flicked out of the box break down into clay, then rinse them down, but this stays like little pebbles and I have to smash them with my finger after soaking them to get them to break down enough I feel comfortable with them going down the drain. On to a flushable version next.

Best Litter Ever

I had 5 saved cats in my house, now 3 are still alive. This litter gets cleaned out daily and there is no smell in the house. This litter leaves no dust also

I had 5 saved cats in my house, now 3 are still alive. This litter gets cleaned out daily and there is no smell in the house. This litter leaves no dust also. The urine and poop get into a ball and easy to scoop up and remove. This litter lasts a lot longer then others I tried in the past 30+ years.

clump & Seal. can you help me with my marriage?

Life changing. Wow. Where have you been all my life?!! Such an upgrade from the fresh step I’ve used for years. It’s grainier like a thick sand. It really clumps!

Life changing. Wow. Where have you been all my life?!! Such an upgrade from the fresh step I’ve used for years. It’s grainier like a thick sand. It really clumps! The cat actually covers it up!! Builds a little sand castle in there. And it doesn’t stick to sides and bottom it just comes out in a ball. No more litter cement! it’s almost pleasing to clean the litter box. Oh and it really keeps the pee pee and poo poo smells away. Occasionally you get a brief whiff when you scoop poop, but then it’s gone. Thank you for changing my cat’s relationship with litter, and my relationship with my cat. Oh great clump and seal... Do you think you can help me with my marriage?

I was using EverClean litter which is very expensive, so we decided to try some cheaper brands to see if they could compare. We tried Fresh Step, Scoop Away, and the regular Arm and Hammer litters (tried multicast, fresh scent, unscented, many varieties in each brand) and with all of them, the house smelled terrible in about a week. I had to completely empty and wash out the litter box once a week to keep the house smell okay, it was such a pain in the neck. We finally tried Clump and Seal and even after months of use, we haven't noticed any stinky smells even for a second. We have an open litter box without a lid, so there is no hiding it when there is even the slightest smell of pee-- but this litter makes it like we don't have a cat, there is ABSOLUTELY no smell. And the clumping is great as well. We have an automatic litter box, so it's important to have a well-clumping litter to make sure the box will be able to scoop it all out. The box looks basically clean and unused every time I look at it because this litter clumps around every single bit of waste.

Years of Use & Still Impressive!

I have been using this brand of Arm & Hammer Cat Litter for years. Since introducing the New SLIDE (purple & black box.) I am COMPLETELY CONVINCED and I have not tried any other brand to see if it was better like the time they said the “Worlds Best Cat Litter ; wood chips? Was free and yes it was a complete waste and messy DISASTER. Before I was using either their multi-cat (red & black box) I initially started using the (green and black box) depending on the sale until now I would normally switch it up and see which consistency I liked best but now with Chewy.com Auto-ship it’s so simple. You can most definitely get 7 to 14 days depending on if you have one or two cats it does not turn into mud at the bottom of your cat litter box and that was my biggest issue with the other Arm & Hammer yellow containers/boxes it was just turning into mush and disgusting that would be all over the place big chunks of cat litter get stuck in their paws and the horrendously awful smell of ammonia in the layer of only 4 days of use instead the new ones as I spoke about above are clumps only where moisture is detected and feces is covered and the smell trapped inside! That isn’t the case with the yellow boxes and I was sick of it. Recently, I learned that some cats are sensitive as to scented litters and can become infected or sick but have no fear because you have a scent free option! Thank you for continuing to become even better than the last type of litter you come out with more and more ways to help indoor cat lovers keep their cats safe and your house clean and scent free!
