When you live with multiple cats, litter performance becomes less about convenience and more about survival. Odor builds quickly, clumps get stressed by volume, and cheaper formulas often break down under pressure. Arm & Hammer’s Clump & Seal Multi-Cat litter is designed specifically for that kind of workload — and in daily use, it largely delivers.
The defining feature here is the brand’s Clump & Seal technology, which binds liquid waste into tight clusters while sealing odor inside. In practice, this means urine smells are neutralized almost immediately after contact. Even in a two-cat test setup, the litter box area remained neutral between cleanings.
It’s not fragrance-heavy, which is important. Instead of masking odors with strong perfume, it relies more on baking soda–based neutralization. That makes it a safer choice for cats sensitive to artificial scents — and more tolerable in smaller apartments.
Clumping performance is the real strength
The clumps form quickly and dry solid. That matters because weaker clay formulas often crumble during scooping, leaving behind damp residue that compounds odor. Here, clumps lift out cleanly with minimal fragmentation, provided you scoop within a reasonable timeframe.
With heavy use (three cats or delayed scooping), edges can soften slightly, but the structural integrity is still above average for a traditional clay litter. For multi-cat households, that reliability significantly reduces daily maintenance frustration.
Dust and tracking: good, not perfect
Despite the “low dust” claim, there is still some fine particulate when pouring from the box, though it settles quickly. During routine scooping, airborne dust is minimal compared to older clay formulas. Tracking is moderate — the granule size is fine enough to stick to paws occasionally, so a litter mat is recommended.
It’s also worth noting that this is not a lightweight formula. The density contributes to strong clumping but makes the box heavier to carry and refill. If lifting weight is a concern, lighter alternatives may be preferable.
Longevity and value
Because the clumps are compact and waste removal is efficient, the remaining litter stays fresher longer. In a typical two-cat household with daily scooping, a box can maintain performance for about a week before needing a full refresh.
Considering its mid-range price point on Amazon Canada, the cost-to-performance ratio is strong. It doesn’t try to reinvent litter — it simply executes the fundamentals at a high level.

Final verdict
Arm & Hammer Clump & Seal Multi-Cat isn’t flashy, but it’s dependable. It handles high-volume litter box use better than most traditional clay competitors and keeps odors contained without relying on overwhelming fragrance. For multi-cat homes that prioritize performance over novelty, it remains one of the safer picks in its category.
