BBC News: Policeman takes 'big cat' video
An off-duty Ministry of Defence police dog handler has taken a video of what he claims is a panther-sized big cat. Pc Chris Swallow was helping a friend with their garden in Helensburgh, Argyll, when he spotted the black creature on a nearby railway line. The officer, who is stationed at the Faslane naval base on the Clyde, said the cat was as big as a Labrador dog. Big cats have been reported in the area in the past, with several sightings of the so-called Coulport Cougar.
The article has the video, but I can't get it to play in Firefox, only in Safari. The animal walked along the train rail, which a dog wouldn't have been able to do, and its tail was much longer than a dog tail. I love stories like this, I've posted about this before.
Urban legend says the cats are decendents of illegally imported big cats that either escaped from private zoos or were released in the 1990s. Big cats in Britain keeps track of sightings, but are they myth or fact?
