Vetsupply: Feliway is a synthetic copy of the feline facial pheromone, used by cats to mark their territory as safe and secure. By imitating the cat\'s natural facial pheromones, Feliway creates a state of familiarity and security in the cat\'s local environment. It can used to assist in comforting and reassuring the cat while coping with difficult situations. It reduces the stress level of the cat and calms them during travel or hospitalization, when moving to new home or when introducing to a new cat into a multi-cat household.
