Not being a trapper, I'll take your word for it. We had cages set up on a friend's land in Texas. It was nothing to find 10 ~ 12 of 'em in the cage the next morning. The big ones would see you, and then run straight at you, slamming into the welded wire of the cage. They'd bounce off and make another run. In fact, they did that until you killed 'em. The only ones that didn't show extreme aggression were the little ones. They just ran around the cage enclosure in a bunch...until they were dispatched.
