Generally known as "wild" and not a domesticated animal, foxes are normally timid animals and steer clear from humans.
Not the case with this particular fox. He was very friendly and became attached to his new pal very quickly, playfully tugging at Henry's bag.
Hoffman eventually had to part ways with his new friend but not before he was able to ensure the fox's safety from the busy streets of London mentioning later in his video post that he stopped a bus from striking the small animal.
Warning to all, this was an extraordinary circumstance. Please DO NOT attempt to make a fox your pet.
