I wonder if there are any foxes left from direct breeding at that fur farm in the 1960s. If there are, I wounldn't mind having one ! They were bred for several generations and became strangley piebald and their ears went floppy and tails curled. They were as tame as a puppy, and well on their way to domestication. As for skunks and chinchillas, they also were domesticated for fur. Cavies were domesticated for food.
