Catnip: Cats Behaving Badly
Cataria nepeta. That’s some strong stuff, man. You don’t want to let your cat drive or operate power tools for several hours after a hit of this stuff. Catnip is a member of the mint family, bland and unobtrusive in the garden, with dull gray-purple flowers. Humans rarely notice it.
