BREEZE Tidy Cat Pellets (3.75 lbs) are part of a unique two-step cat litter system that will make you want to throw away your current cat litter box for good. Why? Unlike other cat litter boxes, the Breeze cat litter system allows your cat's urine to pass through the Breeze Pellets and onto the super absorbent Breeze Cat Pad. Solid waste stays on top for quick and easy cleaning. Change cat litter only once a month. Eliminate strong odors in your home. No more dusty paw prints or dust clouds. How it works: The unique Breeze Pellets are larger than traditional clay pieces. These Pellets allow urine to pass through to the thick and absorbent pad below, keeping solid waste at the top for easy removal. Best of all, these Breeze Pellets only need to be changed once a month. The super absorbent Cat Pads can last for up to one week, but should be changed every 3 days if you have more than one cat. Flushing the Breeze Pellets is not recommended. Cautions: This litter box may be difficult for cats with joint or mobility problems to enter. If needed, the Breeze Litter System is adaptable to use without the walls.
