Good possibility, Rich. Last year we had a confirmed mountain lion in Lyon county (yup, Lyon Co.) in the extreme NW corner of Iowa. Also last year, I got the crap scared out of me when one screamed less than a quarter mile away as I was getting out of my stand while bow hunting in Obrien county. Made real good time getting back to the truck, lol.
We think these cats are passing though, but there are a few areas which may have enough habitat to cause them to stay a while, such as remote river bottoms. We don't get reports of livestock being taken, but then we are infested with deer here. Several years ago we had a moose wander through, and an elk is spotted (and confirmed) about every other year.
So . . . have ya taught Mom how to load and shoot a 12 gauge auto yet? Pretty cool to have those tracks locked up in concrete. Maybe the zoologist from Henry Dourly Zoo would stop by and have a look?
