Here is a link for current work the Russians are doing, and they have a line of very friendly foxes.

There are pics of some amazing colors of foxes on the fur farms.
A couple decades ago I had a fur farming license here in Illinois.
I had red, silver, and white spotted foxes that I raised on a bottle that were tame enough to play with us in the house, with the dogs :)
Just out of curiosity, do the hand raised ones lose their rather strong smell?
