Who is it for?
This litter is designed for households with two or more cats, where odour and scooping frequency are the biggest pain points. It suits cats of all ages and breeds, and it's a practical pick if you want a familiar clay clumping texture most cats accept without fuss.
How does the odour control work?
The formula combines Arm & Hammer baking soda with moisture-activated micro-granules. When urine hits the litter, the granules activate and the baking soda neutralizes odours as clumps form — helping keep the box fresher between full changes.
Feeding & use
Fill a clean litter box with about 3–4 inches (7–10 cm) of litter. Scoop clumps and solid waste daily, top up as needed, and empty and wash the box fully on a regular schedule — more often in multi-cat homes. Transition gradually by mixing with your current litter over several days if your cat is sensitive to change.
What else should I consider?
In a busy multi-cat home, the general guideline is one litter box per cat plus one extra, spread across quiet locations. If you're comparing options, you may also like the Arm & Hammer - Slide Multi-Cat Cat Litter for easier box cleaning, the Intersand - Simple Clumping Cat Litter for a straightforward clay clumping option, or the Naturally Fresh - Multi-Cat Clumping Cat Litter if you'd prefer a plant-based alternative.
