His problems are bigger than the title suggests. Badgers are normally shy animals, but these ones are happy not just to live close to humans, but right underneath them. His house won’t be sitting directly on the earth, so these badgers are also capable of digging through the actual foundations. Those are some scary critters. No wonder Natural England told him to move out. I suspect he misheard what they said, which was actually “run and don’t look back”.
