Some ferrets do make a barking noise. It is among the normal ferret vocalizations. Actually, long ago I read an article on ancestral sounds. Some sounds have variations among a range of mammals, birds, and even at times reptiles. If you think about it we humans use those inflections, too. A sharp burst is a bark and that is among the old ones. So are purr (think of cuddly voices rather than the most exaggerated examples which are among the cats and some birds), scream, hiss, and one or two more that i forget. Really, really old shared sounds...
