This Kitty Litter is a life saver! It clumps up well and is so easy to clean. It doesn't track that much either! I don't have pictures, you just have to trust me. I do have this really cool mat that he walks out on out of the kitty litter. It has holes in it to trap the litter on his feet. Good kitty litter and good price and Thank You Amazon for bringing it to my door, I am forever Grateful at age 66 with a bad knee. Thank you so much!!

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.

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.

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.

This is a good clump style cat litter that can be "scooped." It absorbs the liquid from what the cat leaves and reduces the smell. The cats are willing to use it and it holds up pretty well. Should still be scooped regularly, especially before guests arrive.

Absolutely the best litter we’ve bought so far. We use an automatic litter box and there have been no residual litter on the filter screen where the unit dispenses into the drawer. Our other litters were awful, I thought it was the box, nope!!! Had no idea it was the litter and I’m happy I gave this a try. Clumping: fantastic Odor: minimal to none (our boy likes to play in his box for some unknown reason 🙄) Quality: excellent. To me, it’s worth it to spend the extra money on a quality litter that just does its damn job then throw money in the trash on bargain brands.

This stuff is absolutely awesome. My cat is proud and motivated to take a dump in her litter box after I started buying this brand of litter from Amazon. The dust level is a little less than other brands. You still have to vacuum regularly and no your cat doesn't know how to run a vacuum. Even if you could teach a cat to run a vacuum, they don't have thumbs. No matter the brand, you should still scoop the doo-doo twice a day per cat using the litter box to keep your cat healthy. This brand has a similar appearance to other brands, especially after my cat drops a deuce in there.
