1. they are out of the wind and the snow has air trapped that acts like insulation
2. they are warm buried under the snow because the snow traps their heat and bounces it back to them.So it's pretty much like a blanket.
3. have you ever heard the song 3 dogs they shiver creatin heat like a cat that purr same efect
