Deb-
 
Those yawns aren't boredom or agitation.... it's a physical reaction to
the petting that no one can really explain.  Wierd, huh?  Don't take it
personally!
 
Remember that ferrets sleep on average 18-20 hours per day, more probably if
they're bored.  But they do like lots of stimulation, and I'm sure a second
ferret would be great company for Brae- it's why we got Jasper for Taz (and
Baxter for Jasper... but I digress).  And really, two is no more work and
twice as much fun!!  (I'm sure you can come up with your own reasons for
ferret math :-))
