Please call our Pet Specialists with any questions or comments: 800-234-2269 (M-F, 7:30 am - 3:45 pm, MST) Directions Plug the pheromone diffuser upright into an unobstructed outlet, away from drafts or windows, in your cat’s favorite rooms. Never use the diffuser upside-down, sideways, or into a power strip/cord. Diffuser gets hot. This is normal for proper evaporation. The diffuser features a rotatable plug to ensure an upright placement in any wall outlet and an automatic safety shut-off to prevent overheating. Use only in properly functioning 120-volt electrical outlets. Improper use may cause the diffuser to become discolored, increase odor due to vapor residue buildup, and/or cause leaking. Replace refill approximately every 30 days.
