Don??t let destructive behavior ruin your relationship with your cat. If something disturbs your cat??s environment, such as a new pet, visitors, moving to a new home or even rearranging the furniture, he may start urine marking, scratching or even stop eating. Comfort Zone with Feliway products help control destructive urine marking and scratching associated with fear or stressful situations. The Diffuser works by using a heating element to disperse the pheromone into the air. Once present, the pet breathes in the pheromone and it attaches to a receptive organ, called the vomeronasal organ located in the nasal cavity. The vomeronasal organ then signals the brain, via nerves, and a sense of well-being is established.
