First, fill the litter box with 3 to 4 inches of this Nature's Miracle corn cob litter. Every day, use a scoop to remove clumps and waste. After scooping, stir the litter to keep it fresh and control odors. Add more litter as needed to maintain the 3 - 4 inch depth. Empty the whole box every two weeks or when the litter is full. Don't flush the litter or put it in drains. When changing the litter, wash the box with warm water and a mild, unscented soap. Let it dry completely before refilling. Just follow these steps, and your pet will have a clean and odor - free litter box.
