Ferrets are forever using their noses to guide them through the world.  If a window is opened, it’s at least an hour’s worth of exciting new things to whiff.  Hippy got a leg up onto the sill and he’s catching some whiffs right now.

In fact, ferrets have a very keen sense of smell, and they use it a lot to seek out fresh water.  I’ve seen Pig, one of our ferrets, a girl, run across the room and stop in her tracks, smelling something.  It’s just a bowl of fresh water I’d put down earlier.  They can smell fresh water vs. old water!
