When used consistently, most cats showed improved behavior after 2 weeks.Just plug the pheromone diffuser upright into an unobstructed outlet, away from drafts or windows in the areas and rooms where your cats spend the most time.

Results may vary by each individual cat. Important information Plug the diffuser into an electric outlet in an upright position with vents facing a ceiling, near where your cat spends the most time. The diffuser uses warmth to fill a room with calming pheromones. The diffuser must always be plugged in upright into a wall outlet and never upside, sideways, or into a power strip/cord. The diffuser features a rotatable plug to ensure an upright placement in any wall outlet and an automatic safety shut-off to prevent overheating. Improper use may cause the diffuser to become discolored, increase odor due to vapor residue buildup, and/or cause leaking. Use 1 diffuser per room. Replace refill approximately every 30 days. Replace diffuser unit every 12 months. Use only in properly functioning 120-volt electrical outlets.. Store at room temperature Shipping We offer FREE shipping on all orders!
