Add to cart Best Catnip Spray For Cats $23.99 Catnip, officially known as Nepeta cataria, is a seasonal plant that can rise to 3 feet above the ground. In its leaves and stems it produces a chemical called nepetalactone which can influence the actions of your cat. When cats are introduced by scent to nepetalactone, it serves as a stimulant and causes some cats to have a behavior uptick. This compound is thought to imitate normal pheromones, acting on certain receptors to induce a response. And when combined with CBD the catnip effects on cats are enhanced.
