Catnip (or Nepeta cataria, as scientists so eloquently call it) is a perennial herb that drives many house cats wild with delight.
It was probably first noticed as an attractant when big cats swarmed around withered or bruised plants growing in the wild.
But how big cats react to catnip? Do they like? Judging from this video of tigers, panthers, and lions attacking bags of kitty pot, then rolling on the ground in a euphoric haze, the answer is yes.
