A drug for cats. It tends to make them crazy, excitable, & generally a lot funnier

A young male who is irresistible to older women, specifically cougars.

Catnip makes cougars go crazy until they lose all of their inhibitions and have to have the catnip at all costs.
Damn that smoking hot cougar bitch couldn't keep her hands off me. She must think I'm some high-grade catnip.
