When our ferrets wag their tails it seems to me that they are saying "I'm going
to get you!".  One occasion for tail wagging has been when one ferret was on
one side of a long tube and another ferret was on the other.  Another time was
when Buttercup, our 8 month youngster was stalking our dog who happened to get
too near the ferret cage.
