Not my usual territory - I'm mostly a spontaneous human combustion man myself - but big black cats are something I've followed a fair bit over the years. We get a lot of reports of them here in Shropshire and the wider UK, places like Bodmin, Dartmoor, you name it. The theory over here is escaped exotic pets from the 70s before the Dangerous Wild Animals Act came in.
My question for you lot is what exactly did you see that made you think it was a cat rather than a large dog? The gait is apparently quite distinctive, that low shouldered stalking walk. Did it move like that? And was the tail long and curved upward or just hanging?
Genuinely curious because the Blue Ridge area seems to come up again and again in these reports and I wonder if theres actually a breeding population out there or just isolated sightings of the same animal. Anyone got photos or know if wildlife cameras have ever picked anything up in that area?
