Just a quick whiff of silver vine sets cats off.

This cat immediately dribbled from just smelling the silver vine but was too timid to play. He did roll around though which they instinctively do to crush/break up the plants leaves/stalks to release more of the nepatalctol (silver vine) or nepatalactone (catnip).
