Details: Simple Setup & Maintenance-1. Snap the sidewall onto the grated base. 2. Place one cat pad (soft side up) in the BREEZE Litter System drawer and slide into the base. 3. Fill the top portion of the box with one 3.5-lb package of litter pellets. 4. Scoop out solid waste and dispose of daily (pellets do not clump). 5. Add more pellets as needed. We recommend that you replace the pellets completely once a month. 6. Slide drawer out to replace the disposable pad. Drawer can be rotated 180 degrees, without touching the pad, to extend pad life. Note-We want to remind those with suppressed immune systems and pregnant women that a parasite sometimes found in cat feces can cause toxoplasmosis. Please wash hands thoroughly after handling used cat litter. Encouraging your cat to use an indoor litter box, or properly disposing of outdoor cat feces, is beneficial to overall water quality. Please do not flush cat litter in toilets or dispose of it outdoors in gutters or storm drains. Used litter is not recommended for garden use. Store in a dry place.
