Believe it or not, scientists have yet to discover why catnip drives kitties wild. They've identified the chemical substance in catnip that causes the effect – it's called nepetalactone, an organic compound. But we still don't know why it works. We just know that when it works, it REALLY works!
According to Dr. Nicholas Dodman, a veterinary behaviorist who runs the Behavior Clinic at Tufts Cummings School of Veterinary Medicine, writing for PetPlace.com, "A cat reacts to catnip with ecstasy and unbounded joy."
Behaviors people have witnessed after offering catnip to their pet include nosing, chewing, and batting the catnip container while drooling buckets; shaking their heads; rolling around and rubbing their bodies on the floor; losing their balance, falling and stumbling around; repetitively kicking their hind legs; and showing excitement and chasing behavior.
Catnip Affects Areas of the Feline Brain Related to Hunger, and Predatory and Sexual Behavior
Dr. Dodman offers a few possible explanations for feline behavior while under the influence of catnip. He believes that since some of the behaviors are playful in nature, catnip puts kitties in the mood to have fun.
Chewing and drooling seem to be associated with getting food, while rolling and rubbing appear to be sexual behaviors. Tandem hind leg kicking could be a predatory behavior, as is chasing.
It seems catnip may inspire bursts of expression of several natural feline behaviors, almost as if the kitty has let go of his inhibitions. (How many of us are more willing to hit the dance floor after a pre-boogie cocktail or two?)
According to Dr. Dodman, "This implies a general excitatory effect on areas of the brain, particularly those centered in and around the hypothalamus, the region that controls appetitive, predatory and sexual behavior."
Catnip May Help Improve the Relationship Between Feuding Felines
Recent research suggests that not only does the nepetalactone molecule have an opioid shape, it also has an opium-like action, meaning it stimulates opioid receptors in the brain in the same way morphine does. Dr. Dodman believes the reason a benign herb like catnip contains such a powerful substance may be to attract insects that will subsequently assist in cross-pollination and other activities beneficial to plants.
When a susceptible kitty gets hold of catnip and absorbs the nepetalactone, her pleasure centers (opioid receptors) in the brain are activated and the next thing you know, she's rolling around in a state of goofy bliss.
Despite the fact that catnip appears to make susceptible kitties "high," it is an entirely harmless and non-addictive herb. It may even help in certain situations, for example, with battling cats. Kitties who don't get along may see their nemesis in a new and friendlier light while under the influence of catnip – and the truce has been known to hold after the effects of the nepetalactone wear off.
In addition, catnip has pain-relieving properties that may be helpful for some kitties, similar to the effects of marijuana in some people.
