NONE OF THE ABOVE! That is the top half and ears of a whitetail fawn.
There's no way it's a whitetail fawn. The ears are not nearly long enough. Has to be a cougar or bobcat, but I'm still leaning toward cougar since I don't see any tufts on the ears like a bobcat has. Also, a bobcat wouldn't be that tall.

We had reports of mountain lions up here in NE MN. I talked to some people during last year that saw wounded deer from the season that had been chewed on by lions.
