I'd say they have the potential to be good pets, definitely not bad ones. Btw it only took nine generations.
This National Geographic article?
It really is an interesting article:
Selecting which foxes to breed based solely on how well they got along with humans seemed to alter their physical appearance along with their dispositions. After only nine generations, the researchers recorded fox kits born with floppier ears. Piebald patterns appeared on their coats. By this time the foxes were already whining and wagging their tails in response to a human presence, behaviors never seen in wild foxes.
