One day my dad left the farm to go take care of something at my aunt'* house and he was only away for 10 minutes. I was outside waxing my first car at the time (1970 Dodge Coronet) as he pulled up, got out, and said, "Kyle do you hear that? Sounds like a cat meowing...I heard it all the way to *aunt'** and back."
Sure enough we pop the hood of the '98 Silverado and one of our kittens was shivering by the fan shroud. How it stayed there so long, I don't know...poor thing got a lot of attenion after that.
