Purina Tidy Cats Breeze Cat Litter Box System.

This innovative system is designed for odor control and easy cleaning through a unique combination of specialized pellets and absorbent pads.  * The system uses anti-tracking, 99.9% dust-free pellets that allow urine to pass through to a disposable pad in a drawer below. 
 * Each absorbent pad locks in moisture and prevents ammonia odor for up to seven days for one cat. 
 * Solid waste remains on top of the pellets for easy daily scooping and disposal. 
 * The system is available as a starter kit, which includes the litter box, pellets, pads, and a scoop.
