Foxes live on large territories, which they mark by scent -- urine or musk from several glands on their body. In a town, foxes can also occupy a smaller territory or even accept other foxes in their territory. Foxes may share their territories with wolves and eagles, they sometimes even follow wolves to catch leftovers from their prey. Coyotes, however are avoided by foxes. Wolves, coyotes, lynx and eagles are his natural enemies and may kill him when they find him -- to save their own territories. The eagle even kills foxes for food.

Foxes can be found from the Arctic tundra (Arctic fox) to city center (Red fox). The red fox is the best known fox, he lives in woods as well as in towns, where he searches garbage bins for food. Foxes are interesting because they seem to have characteristics of both dogs and cats. Some of their cat-like characteristics include: vertical slit eyes, partially retractable claws, light body weight, and a stalking and pouncing style of hunting. Foxes are even good tree climbers, especially the gray fox.

Red foxes generally have a white belly and almost always have a white tipped tail, black ears and paws, called socks, are common. The red fox does have a wide range of possible colors. Some have a light grey color -- the light silver fox. One color phase that is prized is the black silver fox -- the fox is solid black with specks of white hair on the hind side and the typical white tip. Most Arctic foxes have a solid white fur color in winter -- however, some have a solid black or dark blue fur color in winter. These blue color phase foxes, called Blue Foxes, generally live along the coast. The Arctic fox's fur changes to dark brown in summer.
