Vomeronasal organ. The vomeronasal organ (VNO), or the Jacobson's organ, is an auxiliary olfactory sense organ that is found in many animals. It lies close to the vomer and nasal bones. It was discovered by Frederik Ruysch prior to 1732 and later by Ludwig Jacobson in 1813. This organ is the sense organ involved in the flehmen response in mammals.
The appearance of the cat as he brings air into the Jacobson's Organ has sometimes been likened to a smile, other times to a grimace which is called the Flehman response. The Jacobson's organ seems to play a large part in the sense of smell of a cat, judging by its frequency of use around my house.
