Most likely what you saw was a mink not a ferret. Ferrets are never a soild black in color. One think to keep in mind if you gap hold of a mink it will gap back they have razor sharp teeth and claw so beware you will get hurt. Another thing to keep in mind this is a wild animal and you will be bite and you have no way of knowing if it has rabies or not. Best to leave it be it knows how to take care of itself and it is much happier free then caged up as a pet. [Posted in FML 6403]
