Do cats get “high” off of catnip?
First, not all cats do react to catnip. It is estimated that one third to half of the domestic cat population is unaffected by the herb. The reaction to catnip is inherited. Kittens that have only one parent that reacts have a one in two chance of reacting themselves, and kittens that have parents that both react have a three in four chance. Kittens under three to four months old do not react to catnip and with older cats the effect is considerably lessened. Also, if a cat that would normally have a reaction to catnip is in a threatening situation, or is outside of its usual surroundings, it may not respond to the catnip. Anyway, as to what causes the catnip effect, the experts do know that nepetalactone, an oil found in catnip causes cats that are sensitive to it to go ga-ga. What they don’t know is why certain cats react that way.
