However, this sort of evidence is hardly headline news; in fact it's extremely common. Every week evidence comes to light regarding 'big cat' activity in the southeast of England such as kills, scat etc. See images:
1) fox killed by black leopard,
2) fox stripped by female black leopard,
3) deer carcass found in a tree,
6) sheep kill.
Hardly ground-breaking news. If the evidence proves that such prey have been taken by a large cat, I don't really see this making a great impact, sadly, as previously hair samples, some excellent photos, kills and even felid bodies have turned up, but it generally dies down after a while. Here's hoping that the abundant evidence proves without a shadow of a doubt that leopard, puma and lynx are roaming Britain, but sadly there will always be those who do not believe such reports. Even if a 'big cat' body turns up - which I hope it doesn't to some extent - I'm sure the sceptical view will be that it's a hoax or a zoo escapee.
