It's ingenious. BREEZE Cat Pads are easy to maintain with minimal odor. The specially-designed BREEZE Litter Pellets allow urine to pass through to the BREEZE Cat Pad underneath, while leaving solid waste on top for quick, easy removal. Urine is quickly absorbed by an odor-controlling BREEZE Cat Pad in a protective tray. Open up your home to carefree living. Let in a clean, odor-free breeze.
