take a second, look for tracks in the snow around your car, look under the hood. It's only 10 seconds, it might save you a LOT of problems. Hell, while you have the hood up, check your oil!

Possums, raccoons, cats, even dogs have been found trying to stay warm and out of the wind under car hoods.

We found one kitten here at my job under a hood. It now has been adopted by a great co-worker
