It can't be said enough...
Take care of the outside pets and farm animals.
One area that people have a misconception is water.
Water is very important for pets to stay warm. (goes for people also)
Some say they can eat snow.
Yes, but the body has to warm that snow and there is very little moisture
ins the snow. If you don't believe me take a glass of unpacked snow and melt it.
See how little water you get.
So, once again...Make sure you give them water!
