flehmen Behaviour, probably with a sexual significance, exhibited by felids, goats, and some other mammals when examining a scent mark (see scent marking). Having sniffed the mark intensively, the animal raises its head with its mouth partly open and upper lip slightly drawn back, stares fixedly to its front, and breathes slowly. Sniffing followed by flehmen may occur more than once at a single encounter with a scent mark.
