Comfort Zone Plug-In w/Feliway
) The Comfort Zone Plug-In Diffuser with Feliway was designed to reduce or eliminate anti-social stress-related behavior in cats. If your cat is distressed or feels threatened, he'll mark his territory by scratching or spraying urine on walls, furniture and other vertical surfaces. This warns other cats to stay away. When your cat is calm and contented, you'll see him rub his face on objects to apply a facial pheromone that marks the area as safe and cat-friendly.
