Giant Ground Squirrel

The Giant Ground Squirrel is the largest squirrel species on Earth, about the size of a cougar. It resembles a marsupial lion (also known as the Thylacoleo), but it is a placental mammal, not a marsupial, and it is herbivorous, feeding on grass, seeds, nuts, roots, tuber, leaves, and berries. It lives in western parts of U.S., including California.
