What are animals really doing when they smell each other?
Like thousands of other animal species, from mammals to crustaceans, dogs trade heavily in chemical secretions known as pheromones. These scent markers not only pass along information about potential rivals and mates, they can actually trigger specific behaviors or even physiological changes.
What does it mean when a cat smells something then opens its mouth?
The flehmen response allows the scent to travel to the vomeronasal organ on the roof of the mouth.” Also called Jacobson’s organ, the vomeronasal organ is a region of sensory cells within the olfactory system of mammals, amphibians, and reptiles. …
Why do goats curl their lips?
By curling their upper lips many kinds of mammals expose the vomeronasal organ (also called the Jacobson’s organ) in the roofs of their mouths and draws scent toward it. This behavior helps them identify what they smell, especially the scent of animals they don’t know and sexy scents, like females in heat.

How does a horse respond to flehmen chemical cue?
Horses exhibit flehmen but do not have an incisive duct communication between the nasal and oral cavity because they do not breathe through their mouths; instead, the VNOs connect to the nasal passages by the nasopalatine duct. The chemical cue obtained by an animal exhibiting the flehmen response is the presence of a non-volatile organic compound.
