While not all cats are reactive to catnip, those that do will display distinct behaviors as they rub and roll on the plant or object that had been wiped with catnip. Rubbing catnip stimulates the release of nepelactone, the oil which can trigger behavior changes in catnip-reactive cats.  Catching a whiff of nepelactone can transform a cat into a seemingly euphoric state. When a catnip-sensitive cat comes across a catnip plant, he may rub or roll on the herb so that most of his body is covered with the oil; some even eat catnip. However, studies have shown that when a cat ingests catnip, it exerts a calming effect rather than a euphoric one. The cat appears relaxed, or even sedated. The effects, however, usually subside after ten minutes or so. It has also been noted that cats that have frequent contact with catnip appear not to react to the plant in the long run.
