Hi Ivan, I think that the ferret mask is not a question of age (other mailers may correct me if I'm wrong). I've already seen 2 to 6 months old ferrets with a clear and visible masks and some others with no mask at all. Also, I have seen a ferret with no mask for the first year of his life and, suddenly (well it seems suddenly for me because I have not see him for 5 months), on the second year, a mask appeared. The season may change the color of the fur too. In winter, the fur become lighter and the mask is less visible than in summer. Also, I have noticed that the mask has a tendency to disapear when the ferret is older (6-7 years or more). I don't know if it is general for all ferret (like gray hairs for human) ? May be someone else may answer the latter. So, it is possible that one ferret have no noticable mask for all his life. -- ======================================================================= Andre Beauchamp ======================================================================= [log in to unmask] (use this one first) [log in to unmask] ======================================================================= [Posted in FML issue 1204]
