ARM & HAMMER Clump & Seal Platinum Cat Litter, Multi-Cat, 40 lb

Litter boxes in a household with more than one cat take on a heavier load than a single-cat box, and ordinary litter can lose its grip on odor long before the next full change. This 40 lb bag of ARM & HAMMER Clump & Seal Platinum is built for that situation. Moisture-activated micro-granules close around waste on contact, sealing it rather than simply absorbing around it, and the formula pairs odor eliminators with ARM & HAMMER Baking Soda. It carries 10% more odor eliminators than the brand's Clump & Seal fresh scent version, with a seven day odor-free guarantee. Plant-derived particles help the clumps set firm enough to lift out in one piece.

Note that this is a granule-based litter, not a crystal or pellet type, and the 40 lb bag ships as litter only, with no box, scoop or liner included.

When setting up the box, pour enough litter to reach a depth of three to four inches, which gives the granules room to clump fully without touching the bottom and breaking apart on removal. In a multi-cat home, plan to scoop at least once daily and top off the level as needed rather than waiting for a full change. Because the clumps seal moisture inside, the used portions lift away more cleanly than with traditional clumping litters, which means the remaining litter stays fresher between changes and stretches the bag further than the 40 lb size might suggest at first. Store the bag in a cool, dry location and fold or clip it closed between uses to keep the granules from absorbing ambient moisture before they reach the box.

This product suits households where litter box traffic is high enough that standard formulas start to struggle mid-cycle. When comparing options in this category, the key practical variables are clump firmness, how well odor is contained between scoops rather than just after a change, and whether the granule size works with your existing scooper. Finer granules like these tend to pass through standard slotted scoopers cleanly, but if you are switching from a pellet or crystal litter, expect a brief adjustment period as cats become familiar with the texture.
