The fox is a creature of the wild. They hunt down small critters and ensure extreme cold climates. And now, you can have them as pets! Though, of course, every US state has its own laws on the ownership of foxes.
These people from the Siberian area of Russia have spent 50 years breeding the perfect pet fox. They are said to be very much like dogs in behavior.
Looks like foxes have been pets for quite some time now, though they probably won't be coming in to the mainstream until more folks take the time to domesticate them.
