We know the fascination many cats have with catnip but its lesser known cousin, the olive, can trigger a similar reaction in cats who are sensitive to catnip. Here’s basically why:
There is something called isoprenoids found in green olives and pimentos that is structurally similar to the active chemical in catnip. This chemical binds to receptors that are used to sense pheromones. The pleasurable effect on normally reserved cats can make then scream, beg or exhibit very excitable behaviour.
Does your cat have the penchant for olives? Watch out next time you are making a martini, your cat may steal your garnish!
