The urban fox, and indeed the rural fox, is beneficial to have around
if you are a keen gardener, or for that matter, live any where rodents
are found. Not only does this asset keep the garden clear of slugs it
also keeps the rodent population down. It feeds on mice, rats and
other small mamals. It will also eat road kills and any discarded food
like pizzas thrown away by the local drunk.

So do students but I wouldn't want one of them near my hen house either
