It's smart and simple. BREEZE Litter Pellets are cat-friendly and non-tracking. Unlike traditional clay litter, BREEZE uses specially designed Cat Litter Pellets. These pellets are 99.9% dust free. BREEZE Litter Pellets allow urine to pass through to the odor-controlling BREEZE Cat Pad underneath, while leaving solid waste on top for quick, easy removal. Enjoy carefree living without litter odor or the mess of fine granules and dust.
