These Animals Don't Care That It's Freezing Outside
Animals are very successful in adapting to the conditions of their living environment. The reason why animals can adapt to ambient conditions where the weather is too cold or too hot is that they can regulate their body temperature.
Deer: These two deer are oblivious to the fact that it is frigid. Probably because their winter coat keeps them warm, even when it's -30 degrees Fahrenheit outside! Each hair on a deer's winter coat is hollow, trapping air that helps them retain heat. Quilts, window panes and house insulation all utilize air pockets in similar ways.
