Only one way to survive a cold spell like this.
1. Find a two legged
2. Sit them down in a warm cozy, quiet spot
3. Give them a reason to sit... offer up the belly for a good rub
4. R E L A X
5. Your relaxed mode will make them chill out because they do not want to disturb you
Pretty soon they will be asleep as well and you are both toasty warm and comfy.
This is my 2 legged, I found him first, go find yourself one....
