“ To a house cat, catnip is a thing of ecstasy. To a jungle cat it holds as much allurement as morphine to a dope user, or whisky to a drunkard. A catnip ball and the world immediately becomes rosy; the great cats roll in it, toss it about their cages, purr and arch their backs, all in a perfect frenzy of delight. Therefore, when they do their work, they get their catnip. When they don’t work they’re simply docked their week’s wages ”
