Used to live in East London on the Isle of Dogs,we used to lamp the parks and waste ground in that general area 3-4 fox was normal,sometimes we would get 5,we didnt used to lamp all night nor travel great distances,Coney Clucky a forum member here was out with us often,his old hancock dog took 100(approx)in a season,a number of them were city fox.London has a large population of fox,they really are brazen and laid back
