We have only had 1 ferret that wagged his tail - that was Frisky.  We
live across the hall from a lady who has a dog.  One time, when she was
taking him out for his walk - Frisky was near the door & smelled
the dog.  Next thing we knew, Frisky was sniffing under the door trying
to reach the dog & his little tail was wagging a mile a minute!  It
was just the cutest thing we'd ever seen.  We only saw him do it one
more time - same circumstances.  Frisky is now over the rainbow bridge -
probably wagging his tail at anyone he sees!  None of our other kidlets
wag their tails - at least not that we've ever seen.
