Big cat sighting in Wales

Sightings of big cats in place where they should not exist are one of the biggest mysteries of cryptozoology. The Beeb has a story on a sighting in Wales:

He saw some people a few minutes later and mentioned it to them. They told him there had been one spotted about a year earlier in the area. "It was jet black and it was really, really shiny. It was bigger than an Alsatian but longer. "If you see a cat, their back is flat and their head is low. A dog is more upright and a tail is swishing. "I don't know much about them really. I've seen these stories in the paper and I've always taken it with a pinch of salt really, but having seen it, it's wonderful.
