The Chemical Behind Catnip’s Effects on Cats

CATNIP: EGRESS TO OBLIVION?

– 4aα,7α,7aα-Nepetalactone is the specific isomer responsible for the catnip effect

☠ Firstly, nepetalactone will enter the cat’s nasal tissue, and there it will bind to certain receptors.

☠ These can then trigger particular sensory neurons to signal to other neurons, and eventually the brain; in particular, the ‘olfactory bulb’, a region at the front of the brain responsible for processing smells.

☠ This region then signals other regions of the brain, including the amygdala, responsible for emotional responses to stimuli, and the hypothalamus, responsible for behavioural responses to stimuli.

☠ This results in the observed response in cats – a response that is actually similar to their response to natural sex pheromones.

☠ The effect of catnip lasts for around ten minutes, and afterwards there will be a refractory period of around an hour where the cat will remain unaffected.

☠ Interestingly, not all cats are affected by catnip; the response is genetic, and autosomal dominant, which means if one parent passes on the gene, then the offspring will inherit the response.
