Why does a squirrel have a bushy tail? It’s for . . .

A. storing nuts.

B. keeping up with fashion trends.

C. staying warm in winter.

The answer is C. When a squirrel is in a tree, it uses its tail for balance. This helps it move from branch to branch. But the tail also keeps the animal warm in winter. A squirrel curls into a ball, using its tail as a blanket.
