Where Do Squirrels Go in the Winter?

Squirrels can generally be seen out foraging for food during the winter as long as the temperatures are not below 30 degrees Fahrenheit and it's not snowing or raining. Squirrels also rely on cached stores of food during the winter. If enough food has not been stored for the winter and the squirrel loses its vital fat insulation layer, it generally will be unable to survive the winter.
