Wisconsin DNR site has lot's of info and locations of wolves and cougars. There are confirmed cougar sightings all over the state including south of Milwaukee near the Illinois border. We hunt in central Wisconsin and the guys bowhunting our land have taken pictures and movies of the wolves. We see the alpha wolf run by somebody's stand every gun season usually chasing a deer. They also saw a huge cougar going into the land. And there is bear sign too. We kill 3-5 coyotes every gun season also.
