The neurophysiological and functional significance of silver vine response in cats: the olfactory system in cats detects cis-trans nepetalactol emitted from silver vine leaves and then stimulates release of β-endorphin; activation of μ-opioid receptors by a high level of β-endorphin evokes rubbing and rolling, which is inhibited by naloxone, an antagonist of μ-opioid receptors; face rubbing and rolling over transfer nepetalactol with repellent activity against Aedes albopictus from the leaves onto the cat’s face, head, and body fur where it helps to protect them from mosquito bites.
