This is a litter deodoriser from Arm & Hammer. Sprinkled into existing litter rather than replacing it, so it works with whatever brand you already buy.
It earns its place in a litter box in a flat or a room without a window. Compare it on how long it lasts rather than on what it costs the first time — that is usually where the difference shows up.
Arm & Hammer is a Church & Dwight brand; the company runs US plants at Green River, Wyoming and Old Fort, Ohio for baking soda, and at York, Pennsylvania and Victorville, California for laundry and cat litter.
