Arm & Hammer Multi-Cat Hardball is a clumping clay litter built around rock-hard clumps and odor control, sold in a Garden Bloom scent. It uses baking soda plus a moisture-activated odor eliminator, and the Hardball clumps are designed to stay together for easy scooping. It suits multi-cat homes that want strong odor control and firm clumps without a lightweight, tracking-prone formula. Against crystal and pine litters it controls odor more aggressively but is heavier and dustier, and its perfumed scent divides owners.
