Squirrels live mostly in climates where temperatures drop during the winter season and food becomes very scarce. How do squirrels adapt to this change in their environment?

Just as they store food underground for use during the winter, squirrels store fat on their bodies in preparation for the cold. When food is scarce, a good layer of fat offers the energy a squirrel might need to survive. It also helps them stay warm when the temperature drops.

Hope this helps !
