It's entirely possible that big cats could be living in the remotest parts of west Wales according to well-known BBC naturalist Iolo Williams.

Earlier this year a group set up to investigate big cat sightings reported a cluster in Snowdonia after people reported seeing large cat like animals and a "massive" paw print. Read about the actual evidence over whether big cats could be on the loose in Wales here.
