If your cat has urine-marked on an indoor surface, use the following easy procedure to help eliminate a cat’s impulse to remark. Works great on indoor plants and Christmas trees too!
Shake well before using. Clean affected surfaces with alcohol or water only. When the surfaces dry, mist-spray No Mark! on affected surfaces twice daily for one week. Then once daily, as needed. If urine-marking should re-occur, just repeat the above procedure.
