“Yo Kid. Want some Olive?“

The smell of the olives causes extreme euphoria in cats, similar to Catnip.
“It's a reaction that (most of) Cats have because olives contain chemical compounds similar to catnip. Not all cats are genetically wired to respond like this - but it's harmless good fun when they do.”
