Previously content with digging holes under garden fences or killing rabbits, the creatures are dabbling in uncertain sectors such as precious metals and energy.
One homeowner from Streatham, south London, told us: “I was in the garden and when I went back into the kitchen, there was an urban fox, just staring at me, unafraid. He slowly closed the utilities purchase he was making on his laptop and sauntered out.”
A spokesman for the RSPCA said: “Urban foxes in gardens used to be very risk averse, and would bolt if you approached them. Now they’re throwing caution to the wind and ploughing huge amounts into Asian football spread bets and Chinese app manufacturers.”
