The Catnip Spray contains catnip root and valerian, which contain nepetalactone, an active organic compound that causes behavioral changes in cats. Cats inhale the aromatic oils of the catnip and valerian root, where they come into contact with specific receptors in their noses. These receptors are connected to the brain and affect the cat's behavior. The allure of the plant extracts in Catnip Spray stimulates the play instincts in most cats, providing a burst of playful energy, usually followed by a mature period.
