Feliway® is 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, Feliway® creates a state of familiarity and security in the cat's local environment.
As a result, Feliway® 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.
The development of Feliway®created a new field in veterinary medicine: Pheromonatherapy.
