Even familiar animals indulge in strange activities. Cats from far and wide are irresistibly drawn to a seemingly insignificant plant. In the presences of catnip, they do the unexpected. They not only eat its flowers, they rub, sniff, and chew its leaves. Cats are strangely addicted to this fragrant herb. They return for a fix of its heady scent again and again. Its aromatic oils make them frisky and playful. As they fall deeper under its influence, their mood changes in other odd ways. As well as rolling around apparently in ecstasy, they chase imaginary mice. This odd behavior is triggered by chemicals found in tomcat urine. Courting females writhe in erotic ways but strangely, catnip affects both sexes. This weird journey shows how natural chemicals........uhhh, I'm drooling. Whoa.
