If this picture is genuine then it could be the best evidence yet that large cats are roaming the countryside. The picture was taken in New Denham near Uxbridge by Paul Keehn and appears to show a large black cat sitting by a fence near some homes which back onto fields. Britain’s leading big cat expert said of the photo "If this photo is genuine it is the best ever photo of a British Big Cat taken in Britain.” and "It's a photograph that would be hard to disprove. I would prefer to have seen another photo of it to see that there's some movement to be sure.” I’m not entirely convinced. What do you think?
