Finding a cat litter that truly tackles odor and makes scooping manageable has been a long and often frustrating journey. I've tried countless brands, but ARM & HAMMER Clump & Seal Platinum has genuinely impressed me, especially with this 37lb online exclusive formula.What I love about it:* Serious Odor Control (14-Day Claim Holds Up!): This is where Clump & Seal Platinum truly shines. With multiple cats, lingering litter box odors can be a real issue, but this litter lives up to its "14-day odor control, guaranteed" promise. The moisture-activated micro-granules seem to work wonders, creating a tight seal around waste and neutralizing odors on contact. My home smells noticeably fresher, even between scooping.* Rock-Hard Clumps: This is a scooper's dream! The clumps are incredibly solid, making it super easy to scoop out urine and feces without breaking apart. This means less wasted litter and a cleaner box overall. It really does form "rock-solid" clumps as advertised.* Low Dust (Mostly): While no litter is entirely dust-free, this Platinum formula is impressively low-dust compared to many others I've used. I don't get that "dust cloud" when pouring or scooping, which is a huge plus for both my respiratory system and keeping the surrounding area cleaner.* Multi-Cat Friendly: It genuinely stands up to the challenge of a multi-cat household. The enhanced odor eliminators are clearly doing their job, keeping the shared litter boxes smelling far better than with previous litters.Things to Consider (Minor Points):* Weight: At 37 lbs, this is a hefty bag! While it offers great value and lasts a good while, be prepared for a bit of a workout when you're getting it into the house and refilling the box. This isn't a flaw of the product, just something to be aware of for delivery and handling.* Slight Scent: There is a very subtle scent to the litter itself. It's not overpowering or unpleasant to me, but if you or your cats are extremely sensitive to any fragrance, it's worth noting. It's certainly preferable to the alternative!Overall:If you're a multi-cat owner struggling with litter box odors and flimsy clumps, I highly recommend giving ARM & HAMMER Clump & Seal Platinum a try. It's become my new go-to. The superior odor control and excellent clumping action make litter box maintenance significantly easier and keep my home smelling fresh. It's a truly effective product that delivers on its promises.

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 ControlThis 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 ClumpsTrue 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-LastingA 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 ConsiderHeavier Than AverageThe 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 HappensDespite 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.
