Many head for warmer climates. Others get ready for winter by putting on a thick coat of fur.
Some animals head underground for a long winter s nap.
This is called hibernation. These hibernators go into a deep sleep. If you saw a hibernating animal you might think it was dead. Sleeping all winter takes preparation and animals that hibernate begin preparing for it in the fall. They try to put on as much fat as possible because they won t be eating much during the winter.
