Arm & Hammer Clump & Seal Platinum Clumping Cat Litter — 37 lb, 99.9% Dust-Free & Heavy-Duty Odor Control

ARM & HAMMER Clump & Seal Platinum is a heavy-duty clumping cat litter formulated to lock in and neutralize odors while producing hard, scoopable clumps for easy cleanup.

Engineered for homes with one or multiple cats, this online-exclusive 37 lb Platinum formula combines moisture-activated clay, ARM & HAMMER Baking Soda, and boosted odor-neutralizing agents to reduce smell and tracking. The formula is 99.9% dust-free and designed to work in standard and automatic litter boxes. With 10% more odor eliminators than the base formula, it’s meant to hold up under frequent use and leave a fresh scent so living spaces feel cleaner between scoops.

How does Clump & Seal Platinum control tough odors?

The formula neutralizes and seals odors on contact rather than just masking them. Heavy-duty neutralizers pair with natural baking soda to chemically counteract urine and feces smells and maintain a fresher smelling litter box for longer.

• Seals and destroys odors 24/7 through moisture-activated clumping.
• Includes ARM & HAMMER Baking Soda for proven deodorizing power.
• Online-only Platinum contains 10% more odor eliminators than the base product.

Will this litter make scooping easier?

Yes — the moisture-activated clay forms firm, scoopable clumps that help reduce tracking and waste. Because clumps hold together, you remove soiled material cleanly and leave fresh litter behind, lowering the frequency of full litter changes.

• Hard clumps for fast, clean scooping.
• Low tracking reduces litter spread on floors and mats.
• Compatible with both traditional and robotic litter boxes.

Is Clump & Seal Platinum safe for multiple cats and automatic boxes?

The product is formulated to withstand heavier use typical of multi-cat households while staying compatible with most automatic litter systems. Its low-dust profile helps protect box mechanisms and keeps the surrounding area cleaner.

• Multi-cat strength handles frequent use without rapid breakdown.
• 99.9% dust-free to limit residue and protect sensors and mechanical parts.
• Works in standard and robotic litter boxes when used as directed.

How long will one 37 lb bag last and what helps it stay fresh?

Longevity depends on cat count and scooping routine; heavier households will need to refill sooner. The combination of higher odor eliminator content and baking soda helps the litter maintain a fresher scent between scoopings, and regular scooping maximizes its performance.

• 37 lb bag gives extended coverage versus smaller bags for convenience.
• Best used with daily or twice-daily scooping for optimal odor control.
• Fresh scent added to help living areas feel inviting longer.
