Feliway Classic is a vapouriser that diffuses calming pheromones. These pheromones are also spread by cats themselves. Because of these unique properties of the Feliway, it helps create a safe territory for your cat. As a result, unwanted fear- and tension-related cat behaviour, such as spraying or peeing in the house, aggression and restless behaviour can decrease or even disappear. In addition, Feliway can help reassure your cat when visiting the vet, the turn of the year, getting used to a new home or introducing a new family member or pet, among other things.
