Can I add litter or use another litter in my ScoopFree litter box?
Never add litter to your ScoopFree litter box or use another type of litter. The Premium Blue crystal litter is formulated especially for ScoopFree. The amount is carefully pre-measured for optimal performance. Too little or too much litter may cause your ScoopFree to malfunction. You can add two handfuls of your old litter to the Premium Blue crystals in your ScoopFree litter box to help your cat adapt when you first use the box without risking malfunction.
