The story that everyone is talking about (well, it got four mentions on Google News) is the Leopard Man of Peckham. That sounds like either a half-wild feral man-beast or a superhero, but it’s actually a man who’s applied to Southwark Council to keep a leopard in his garden. And he lives in Camberwell. Guardian journalist Zoe Williams, a resident of these parts, goes in search of him (and gets nowhere).
I enjoy looking out of my window after midnight and seeing the foxes padding through the streets, and the squirrels in Lucas Gardens are very entertaining; I’d love to see leopards introduced into the local fauna. Not sure how happy a leopard would be in urban London, however.
