Recently a very important warning began spreading around the Uk. But this warning can easily be applied to the US and to any other country that experiences cold, blustery winters.
As the winters in some countries can be too freezing it becomes extremely difficult for stray animals to deal with the cold. So they find alternative places to warm up a bit.
Most of all they like to sit in the wires of the cars to warm up. So it is too important to check your car before starting it up. There can be a small critter under it and by being attentive you can save one more life.
