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. Bill Sebok [Posted in FML issue 0921]
