Hi - I didn't notice anything in the FAQ about this, but how common is progressively poor eyesight in ferrets, I seem to remember reading that it was. Our one ferret, Larsen, seems to have very poor eyesight and when you look in his eyes they are grayish(like cataracts) and this was not the case when we first got him 3 years ago. He doesn't seem to care one bit but he does get confused a lot. - Ron [Posted in FML issue 1204]
