Swift fox

The swift fox is a petite, sandy-colored fox about as big as a house cat, darting across the Great Plains of North America. It thrives in grasslands from Texas up to Canada, where it was once wiped out but has since returned. This little fox is a close cousin to the kit fox, though scientists agree they're separate species.

• About the size of a domestic cat.
• Lives in the western Great Plains grasslands.
• Sometimes interbreeds with kit foxes where their ranges meet.
