May I present the mink. Being a trapper since my younger days, this small member of the mustelid family is probably the most difficult fur animal to trap on a profitable base. A few minks in your fur bundle is not an achievement in itself, but taking thirty or so minks means that you have the habit’s knowledge of this small ghost which leaves very few signs. Furthermore, for the size of this animal, they cover a very large territory, especially the males. Like for the deer, the trapper who took the time to understand the needs of this animal and his natural diet will eventually find him and take advantage of it. Two secrets : fresh baits and good lures. Have a good day.
