This is a late reply, as I am behind on the FML (only 4 more days and I'm done with school for the semester!!!) Someone asked about a deaf ferret and the possibility of gaining hearing. My deaf DEW has not gained hearing to speak of, but I have noticed that there are certain sounds that he does seem to hear. I don't know what those sounds are specifically, but it must be something at just the right pitch & frequency. When it happens he comes to a complete stop, looks very startled, then very alert and he looks all around trying to figure out where that noise came from. It is an unmistakable reaction that I've witnessed about 20 times. I wish I knew what it was he can hear - but I'm clueless. I should probably try a dog whistle or something, because I swear it's something that I'm not hearing when it happens. Holly [Posted in FML issue 3808]
