    • This is for the SLIDE and Clump & Seal

SLIDE I ordered a box of the slide to try it. Since it has been mixed with the Clump & Seal, I can't say that it works as described. I do like the fact that it has low dust and the color is darker than the clump & seal. I also keep the letterbox full enough that nothing sticks. I don't like that at all so I avoid it like the plague! CLUMP & SEAL This has the texture of sand with a very nice smell. It does a good job with clumping in smaller balls than the Fresh Scent brand I was using, so hopefully this will last longer. Though it does smell nice initially, it does not hold on to the smell for 14 days. I found the litter box had a bad smell by three days so I have to make sure to scoop the litter, no longer than three days. Two days would be better and one day would be best. ... show more

This is great cat litter. It is more expensive than the store brands but is worth it. It is easy to scoop and clean. It guarantees no odor for 14 days but with cleaning after 2 cats, the box only lasted 7 days. I will buy it again.

    • Reliable, Affordable, and Perfect for Automatic Litter Boxes!
Size: 18 lbs Pattern Name: Clump & Seal Platinum Clumping Ca...
The ARM & Hammer Clump & Seal Platinum Cat Litter has become a staple in our home. What stands out immediately is how excellent the clumping is — truly one of the best we’ve used. Because it forms such solid, tight clumps, it works beautifully with our automatic litter box. The better the clumping, the smoother the machine runs, and this litter delivers every time. When the box is cleaned regularly, the odor control is impressively low, keeping the space fresh and manageable. Like any litter, if it’s forgotten for a few days, the smell does creep in — but that’s more of a universal truth than a flaw of this brand. Same truth with the weight, par for the course. It can get a little messy and slightly dusty, but honestly, that’s par for the course with most litters. The dust level here is mild enough that it doesn’t bother us or our cat, and the performance more than makes up for it. What really seals the deal is the value. For the quantity you get, this is one of the best-priced litters out there, especially considering how well it clumps and how compatible it is with automatic systems. It’s absolutely worth the money, and we’ll keep buying it. Highly recommend for anyone with an automatic litter box or anyone who wants strong clumping without breaking the bank. ... show more

This is the best cat litter I have ever used. Terrific absorbance and reduces the smell. I scoop twice, or sometimes three times a day and add a dusting of fresh litter once or twice a day to maintain a depth of about 2.5 inches in both of their large litter boxes for my spade female and neutered male. They like the litter, it's easy on their paws. ... show more

    • Tried a bunch, but this is now my go-to litter
Size: 18 lbs Pattern Name: Clump & Seal Platinum Clumping Ca...
I have tried a bunch of litters, to include the expensive crystal litters (all made all of my cats have runny noses). If you’re a cat owner, you know that a good litter can mean the difference between a fresh-smelling home and one that constantly reminds you of your pet’s presence. Arm & Hammer Clump & Seal has earned a reputation for being one of the top contenders in the world of cat litter, promising powerful odor control and easy cleanup. But does it live up to the hype? Here’s a deep dive into its performance. 1. Excellent Odor Control This is where Clump & Seal truly shines. Thanks to its patented “Seal” technology and heavy dose of baking soda, it neutralizes odors on contact and keeps them locked in. Even after several days of use (with regular scooping), there's little to no ammonia or fecal smell and i have three cats. 2. Hard, Tight Clumps True to its name, it forms solid clumps quickly. This not only makes scooping easier but also helps reduce the amount of litter wasted during clean-up. A firm clump also means fewer bits breaking off and contaminating the clean litter. Just wait a little time after the cats pee. 3. Low Dust (Compared to Others) While not completely dust-free, Clump & Seal performs better than many traditional clay litters. It's a good choice for those with respiratory sensitivities — both humans and cats — though those with severe sensitivities may still want a truly dust-free alternative like crystal or pellet-based options. 4. Long-Lasting A box tends to last longer than expected due to the clumping efficiency and odor control. I can stretch one box over multiple weeks with consistent maintenance, making it economical in the long run despite a slightly higher price point. ⚠️ Things to Consider Heavier Than Average The dense clay makes this litter heavier than some competitors. This can be an issue when hauling large boxes or filling the litter box. It’s also not ideal for automatic litter boxes, which often require lighter materials. Tracking Still Happens Despite claims of being low-tracking, some granules do make their way out of the box, especially if your cat is an enthusiastic digger. A litter mat can help minimize this, but it’s not a total non-tracker. If you're looking for a high-performance, low-maintenance litter solution — especially for a household with multiple cats — Clump & Seal is a strong choice. ... show more
