Were you aware that June 15th is traditionally known as “World Catnip Awareness Day.” Are your cats celebrating? The origins of this cat holiday are somewhat of a mystery, but most cats don’t care…and it turns out that approximately 50% of cats have no interest in it… that’s because the sensitivity to catnip is genetic.
What is Catnip, anyway? Catnip is a member of the mint family, which has about 250 species. The essential oil in catnip, nepetalactone, has a powerful effect on cats who are sensitive to it, turning even the most sedentary couch potato into a flipped-out ball of ecstasy. Researchers aren’t sure what the neurological explanation is, but it’s thought that catnip mimics feline “happy” pheromones and stimulates the receptors in the brain that respond to those pheromones. When eaten, however, catnip seems to have the opposite effect: the cat may become very mellow.
Most cats react to catnip by rolling, flipping, rubbing, and eventually zoning out. They may meow or growl at the same time. Other cats become hyperactive, running around like their tails are on fire. They must protect their toys! Usually these sessions last about 10 minutes, after which your cat loses interest. It may take as long as two hours for him to “reset” and become susceptible to catnip again.
Not all cats fall for catnip. It’s an inherited sensitivity, and if your cat didn’t get that gene, he simply won’t care about catnip. An estimated 50 percent of cats don’t respond. The trait doesn’t emerge until a cat is between three and six months old; until then, a kitten will not have a response.
