That's a medium size mountain lion. Two winters ago, a lion was witnessed from just west of Eau Claire (somewhere in MN) to central WI. Took about a month to go 300 miles. People pieced together the sightings and tracks.
Last fall, one was seen and tracks verified in Washington County, which is 50 miles from Milwaukee. And YES, the DNR denied it. They said it had to be a domestic cat cuz bobcats aren't that far south either... in the middle of a corn field... with a 3 foot tail.... with a print the size of a large dog
