When a cat feels safe and secure, it rubs its head on objects, leaving behind
facial pheromones. These pheromones mark the environment as safe and secure.
Feliway is a synthetic copy of this pheromone and is proven to reduce or prevent
stress-related behaviours. The Feliway Refill is designed to replenish the
diffuser; up to 6 refills can be used before replacing the unit.
