I've caught lots of them. More old wives tales about wolverines than any other animal. I was setting wolf snares around a moose that wolves had killed one time. I was working around the kill in a large circle setting snares on every wolf trail leading to the kill. As I was working my way through some thick willows I saw something brown laying on the snow. At first I thought it was a bit of moose hide, but as I got closer I realized it was a dead wolverine. The wolves had obviously killed it. The carcass was still warm so it had happened recently. Crazy part was the hide wasn't damaged at all. When I skinned the wolverine later I found one small hole right behind the front leg where a canine tooth had went in. I guess a wolf must have grabbed the wolverine and just held it until it died. No idea why that wolverine didnt climb a tree to get away but it didnt.
