Arm & Hammer cat litter deodorizer has been a helpful add-on for me. I sprinkle a little into the box between full changes, and it refreshes things without overpowering scents. I use it alongside Arm & Hammer clumping litter. With Pure Cravings wet food in the mix, extra deodorizing really helps. I wouldn’t rely on it alone, but as a booster, it’s solid.
