The fox squirrel is Minnesota's biggest tree squirrel. Some get so big they look like an orange cat in a tree. Fox squirrels are found in most of the state, except in the extreme northeast. These squirrels are not as agile as red or gray squirrels. They sometimes fall from trees but rarely get hurt.
