Don’t let your kitty’s stress-induced anxiety become a cat-astrophe. Plug the Beloved Pets Calming Diffuser Refill & Anti Anxiety Cat Calming Diffuser into an electric outlet and fill your cat’s favorite room with calming pheromones. The diffuser uses warmth to fill a room and naturally eases your paw-tner’s anxiety. It features a rotatable plug to ensure proper, upright placement in any wall outlet and an automatic safety shut-off to prevent overheating. Never plug the diffuser in upside down, sideways or into a power strip—improper use may cause increased odor, leaking and discoloration. You only need one diffuser per room. Replace the refill every 30 days and the diffuser unit every six months.
