Barn cars (outdoor cats) will walk up your windshield and sleep on the roof of old cars, they like high places BUT cars are death on SNAKES!
True story. A couple of decades ago, I went to buy a Roadrunner project from a car bud near Billings, (yes Mo not Mt) just down the road from you. I was under the car looking it over when he drove up from work. He asked did I noticed the bullet hole in the rear qtr. He then mentioned he made it making a hole on the large copperhead living in the trunk.
We used to have snakes here ( copperheads, timber rattlers, coral snakes etc etc) till the outside cat herd came to be about 6 head!
