Above: Original case image: Big Cat Photographed Hatfield Forest, Essex, UK on March 11, 2014
Lynn Lacy, 56, took the photograph on her iPhone after she spotted the animal on the edge of Hatfield Forest on March 11, 2014. She says that it had a long swishing tale, was jet black and prowling. She said she looked out and saw a black cat. It looked too big to be a dog or a cat but too small to be a horse. What she means is it was too big to be a domestic cat.
Looking at the photograph, which by the way is a very poor quality for an iPhone, I conclude it must be a heavily cropped photograph; but even that is unlikely because when you do that you create a telephoto effect and this photograph does not have a telephoto effect of the kind you would expect if you cropped a photograph heavily. So something is rather peculiar about the quality of the photograph.
Blow up: Big cat? or perhaps just a very big dog?
