You can use Feliway Classic spray in your home or on-the-go to comfort your cat wherever and whenever they need it most. At home, spray at least once daily wherever your cat is peeing. Outside the home, you can spray directly on bedding, inside a cat carrier or in your car. Use at least 8 sprays per area to be treated—which will last 4-5 hours on the surface to which it is applied. Never spray directly on your cat. And wait 15 minutes after applying before allowing your cat near the treated area.
