I dont understand what a sensitivity to high pitched sounds has to do with
domestication.  As far as that goes, all "domesticated" animals still have
some degree of self preservation/fighting instinct, prey drive (carnivors)
including humans.  We are still domesticated.  That some ferrets seem really
bothered by high pitch sounds may be a result of the fact that they're
carnivores or not.  It could be it just really hurts their ears.  I think it
was a good idea to rehome the noise sensitive ferret (although it may have
gotten used to the noise its best not to take chances).  However I don't
think it invalidates Bob's theories at all.
