hello again . my new ferret is doing great , and i think i love him more everyday. I have heard about deafness in ferrets , and i have heard that it is common in ferrets with white heads or a white stripe on their head. my Willy is a silver mitt , with a white stripe on his head . I always thought he was a really sound sleeper because you could vacuum right beside him and he wouldn't wake up , but now i'm wondering if he might not be deaf. he doesn't seem to hear you when you call him , or tell him no or something, but will look around if you thump the floor or tap on a wall. how would i know for sure if he is deaf , are there tests to tell . I'm not really worried about owning a deaf ferret , but was wondering if there are any types of training techniques especially for deafness , i don't want him to grow up undisiplined and bad, for lack of a better term. love to all fuzzy babys out there.
