    • 5.0 out of 5 stars Best clumping litter we’ve tried - no more stink!
Style: Clump & Seal Platinum Clumping Cat Litter
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

    • The best litter!!!
Style: Clump & Seal Platinum Clumping Cat Litter
THE BEST LITTER!!!! I have three cats and all are between medium fluffy to very fluffy and I have tried at least three dozen different litter brands and types, from pine to different clay to crystal litters and nothing compares to this one. 1. It keeps smell in SO WELL!!! I only smell it when they first take a big dump but as soon as it’s dug up the smell disappears. 2. Scooping this litter is almost enjoyable, therr is little to NO smell at all, even if neglected for a few days. It scoops very well and clumps amazingly. 3. My cats love it, it is not dust free but isn’t super dusty. 4. My fluffy cats almost never track or have litter stuck to them. I always buy the bigger one and it lasts a decent amount, usually around a month. If you hate stinky litter when you scoop this is for you. Ps it works great in my automatic litter box too. ... show more

    • ARM & HAMMER Clump & Seal Platinum - A Game Changer for Multi-Cat Homes!
Style: Clump & Seal Platinum Clumping Cat Litter
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

    • Great, and perfect for small spaces
Style: Clump & Seal Platinum Clumping Cat Litter
The litter box unfortunately lives in our home office (that I use every day). So I was on the hunt for a litter that would make that set up feasible. I've used this one for years now and it is awesome! I can still smell immediately after the cat uses the litter box but the scent goes away quickly! It's also not super dusty which I really appreciate. My cat does track it a little bit in the area around the litter box but I don't find litter anywhere outside of my office. Clumping is good and easy to clean. I won't use any other litter now! ... show more

    • Excellent Odor Control, Super Absorbent, Great Value
Style: Clump & Seal Platinum Clumping Cat Litter
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

Hands down the best cat littler I've used. It's a great value when you find it with a coupon and there is no dust. The scent isn't strong as well. Scoops up nicely into clumps

    • The only litter I buy after trying so many
Style: Clump & Seal Platinum Clumping Cat Litter
We live in a small apartment and my litter can't let me down. I can't stand walking in and having it smell like ammonia cat pee. I usually can't smell it unless it needs to be cleaned. Superior litter and we have tried A LOT. Clumps hard to remove easily. I don't think there's a scent because it's powered by baking soda. ... show more
