Ssscat! is a motion sensor activated spray product that keeps your cat (or dog) away from off-limit areas (e.g., furniture, counters, windows, plants or fragile objects). The motion sensor and direction of spray is adjustable and the scentless spray is stainless, ozone friendly and has no side effects. When the movement of a pet is detected, the spray is automatically released toward the pet and the pet leaves the off-limit area.
