Actinidine

Actinidine is a chemical purported to be attractive to cats and is found in valerian root. Cultivators of Actinidia polygama (silver vine), which also contains actinidine, sometimes find their plants destroyed by enthusiastic cats. It is similar in structure to nepetalactone, the active compound found in catnip.

Actinidine is also a pheromone for a variety of insects.
