To them, cars may seem like the perfect temporary shelter — the engine is warm, and it  provides shelter from the biting winds — until the car starts moving.
Drivers need to be careful about these stray cats. 
Please knock on the hood of your car before starting your car, as these organizations warn

Luckily, this user noticed before driving off.

Please, please check your car for stowaways before driving, especially if you’re making a short stop and the car is still warm when you start the engine.
