Westwell leopard ?

Report received: Saturday October 20th 2012 - dusk. "I live in Westwell near Ashford. I have just driven into the village via Watery Lane, as I passed under the rail link bridge, I saw a large black cat walk across the road about 100 yards in front. It was roughly the size of a labrador. It was definitely a cat I am really interested in cats in general and can honestly say that just by the way it was walking and its stance that is what it was. It wasnt in any hurry so I got a good look at it. I am totally amazed and thought I would let you know asap."
