Is this a 'big cat' caught on film in Gloucestershire ?

The Sun online have today featured 'exclusive' and 'conclusive' video footage of an alleged 'big cat' caught on film in Gloucestershire. As usual it's in the distance, and whilst the animal appears to have a long tail, sceptics would once again have the right to argue that it is far from being the conclusive proof it is made out to be. Numerous and very similar examples have been floating around the internet for years - strangely, witnesses always feel the urge to plaster their footage on You Tube or rush to major tabloids, however inconclusive their evidence is.
