    • 5.0 out of 5 stars Best clumping litter we’ve tried - no more stink!
Style: Clump & Seal Platinum Clumping Cat L...
We’ve got two cats who are absolute litter box terrorists, so we’ve been through a lot of brands. Switched to this ARM & HAMMER Clump & Seal a few months ago and it’s been a total game changer. The clumps form hard and solid right away — no breaking apart or turning into mush when you scoop. Just lifts out clean every time. The odor control is legit. Between the baking soda and whatever else they put in it, the box stays fresh for days even with daily use. No more walking into the room and getting hit with that nasty ammonia smell. We have the multi-cat formula and it handles both cats without any issues. Dust is way lower than the cheap stuff we used before. My wife has allergies and she hasn’t complained once. The litter tracks a little but nothing crazy, and it stays in the box better than some of the lightweight ones. We buy the big bags because we go through it fast, but it lasts longer than most because the clumps don’t crumble and you don’t end up scooping out half the box. Definitely worth the price for how much easier it makes daily cleaning. If you have cats and you’re tired of dealing with smelly, sticky litter, give this one a shot. We’ve already repurchased twice and won’t be switching back. Highly recommend! ... show more

    • Excellent Odor Control, Super Absorbent, Great Value
Style: Clump & Seal Platinum Clumping Cat L...
Clumps tightly and controls odor extremely well; absorbency is impressive and it soaks up messes fast, leaving the box drier between changes. The 37 lb size provides strong value for the price and cuts down on frequent restocking. Low tracking and easy scooping make it a top choice for multi-cat homes. ... show more

    • ARM & HAMMER Clump & Seal Platinum - A Game Changer for Multi-Cat Homes!
Style: Clump & Seal Platinum Clumping Cat L...
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. ... show more

    • Highly Effective Odor Control and Clumping Performance in a Multi-Cat Household
Style: Clump & Seal Platinum Clumping Cat L...
In a four-cat household, litter performance is critical, and Arm & Hammer Clump & Seal Platinum has been consistently reliable across key metrics. Odor control is excellent. The baking soda formulation provides sustained neutralization rather than simply masking odors, even with frequent use. This is particularly important in multi-cat environments where ammonia buildup can become an issue (and an intense one) Clumping is notably strong and cohesive—forms firm, well-defined clumps that do not fragment during scooping. This improves hygiene, reduces waste, and extends the usable life of the litter. Equally important, all four cats accepted the litter immediately with no signs of aversion. The texture appears to be well-tolerated and comfortable underfoot, which is a significant factor in maintaining appropriate litter box habits. Overall, this product performs at a high level in terms of odor control, clumping integrity, and feline acceptance. It is a solid choice for multi-cat households requiring consistent and dependable litter box management. ... show more
