Groundhogs

Groundhogs, also known as woodchucks, are the largest members of the squirrel family. They spend their days foraging for plants and digging burrows. The burrows help the groundhog evade enemies and predators. Groundhogs hibernate all winter, and emerge from their dens in February. Groundhog incisors grow about a sixteenth of an inch each week, and must be ground down when the animal chews its food.
