I wonder if we wouldn't have had such a problem with feral pigs in the south if American's in their stupid wisdom, hadn't have (pretty much) eradicated all the large predators that were native to the area....(panthers/jaguars, cougers, wolves, etc)....Although pig-mommas can be very nasty, and personally, if I were a 150 pound couger I wouldn't want to go up against an adult one-on-one if it was healthy.....But I'm sure a wolf pack could take one down......
