by Jen on November 13, 2010

While we’re waiting for you to donate more $, I thought you might like to learn a bit about the animal kingdom.

You’ve met Roamy, the mustang.

from Wikipedia:

In the flehmen response, animals draw back their lips in a manner that makes them appear to be “grimacing” or “smirking”.

The action, which is adopted when examining scents left by other animals either of the same species or of prey,

helps expose the vomeronasal organ and draws scent molecules back toward it.

This behavior allows animals to detect scents, for example from urine, of other members of their species or clues to the presence of prey.


What Wikipedia fails to mention is that the Flehmen Response may also occur after “the animal” licks the metal basket on an all terrain vehicle primarily used in the cross-farm transport of hay.

Finally getting a chance to catch up on blogathon posts from all the bloggers :D

My cats do the Flehmen Response a lot, especially (oddly enough) when their investigating my bag when I return home from classes. I like to call it their “stinky face.”
