Dear Edward, Is it possible that your ferret is magnetically sensitive through tactillation of the posterior hairy appendage in which he has the ability to sense openings somewhat like a water witching stick, or does maybe he possess a telepathically induced ability to coordinate his posterior with locations sensed from a local global postioning navigational unit, loran c, or satnav? This subject would make for much more interesting reading and debate and discussion that MF, Pet stores, etc and couldn't possble ever be the source of flames, ..or could it? LOL Tactillation? I like that word! Happy holidays and hugs, Ferretguy [Posted in FML issue 3272]
