Domestic cat's vomeronasal organ acts like a gas chromatograph!
The domestic cat's vomeronasal organ is also called Jacobson's organ. It is in the roof of the mouth. It allows a domestic cat to detect in a very precise way the odours in the air and which enter the mouth when the cat breaths in. You can see that the cat is checking the odours in the air because their mouth is slightly open and the cat is static as if concentrating. This behavior is called the Flehmen Response . Snow leopard Flehmen response. The cat has his/her mouth open. Photo is a still from the video below. A recent study did some work on how the vomeronasal organ works and they likened it to the sophisticated human parallel coiled gas chromatograph! In the scientific world, the gas chromatograph is a sophisticated device which is used to separate and identify components in a volatile sample. It measures the various components in the sample.
