A synthetic copy of the feline facial pheromone, used by cats to mark their territory as safe and secure. By mimicking the cat's natural facial pheromones, it creates a state of familiarity and security in the cat's local environment. As a result, it can be used to help comfort and reassure cats while they cope with a challenging situation and/or help prevent or reduce the stress caused to a cat during a change in their environment. This development created a new field in veterinary medicine: pheromonatherapy. Contains a plug-in diffuser and 48ml refill, will last approximately four weeks.
