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

It has great clumping ability however it is super fine and get stuck to my cat's feet. Then it tracks onto my kitchen floor and I'm walking on cat litter all the time. Unless the "dumps" are completely covered the odor control doesn't work very good.

This is for the SLIDE and Clump & Seal
Size: 18 lbs Pattern Name: Clump & Seal Platinum Clumping Ca...
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

Nice Clean Looking Litter
Size: 18 lbs Pattern Name: Clump & Seal Platinum Clumping Ca...
I bought this litter because it was on sale and we really liked it. The litter is a white-ish color which I prefer than the darker clay color that the orange arm and hammer box comes with. I guess because you can see how clean the box or robot actually is. It is lightweight. I also feel it clumps better than the orange box. It clumps tightly and completely. I definitely prefer that more. I would buy a bigger size though if they offer. We have 4 cats and bought two of this size and because we have two litter robots, it has lasted roughly 5 weeks so far. It is a bit dusty so beware. No strong odor. Anyways, I hope my review helped you make a decision. Lord Be With You! ... show more
