Having trapped more than a few foxes, including arctir foxes... Coyotes, wolves and lots more... Likely it is a farmed fox. It is not coyote, arctic fox, silver fox or anything natural. By natural, I mean genetics have been altered by breeding to produce a different color fox.

I have examples here, full-skin, of just about every natural color of fox; red, black, cross, bastard, arctic, blue, silver, gray, and others.
