In the Great Witchingham case there was a zoological park not that far away that included the Eurasian lynx but who denied any escapees. So equally you can argue a lynx would be attracted to this area for the very reason there were other lynx in the vicinity. In fact, its the same claim made about Dartmoor Wildlife Park's captive big cats attracting 'wild' big cats:
.... see towards the start of the above documentary.
It just seems that, as with UFOs, the media denigrate genuine witness experiences by hyping up every misidentification/hoax and drawing wild conclusions. There are people who have had genuine strange experiences including, for example, lights at night when driving that have interacted with them/their vehicle yet any attempt at a rational explanation is swamped by the media on one hand and wide-eyed self-titled 'investigators' on the other (see the 1992 A70 UFO incident). Likewise, there are plenty of rational witnesses to the alien big cat phenomenon, in fact more so than UFOs, and yet the media immediately steam in and shout "It's the Beast of [insert location here]!!!" and find someone who has taken a blurry photo of next door's moggie, or a smug journalist drives down from London and declares that ABC sightings are just "A manifestation of our desire for there to be something wild and dangerous in our environment blah blah crikey must hit the road, dinner at Fiorella's tonight, laters!"
Rant over
but yes, we have cast iron examples of wild big cats from lynx to puma in our countryside and yet the topic is still treated akin to Nessie and Bigfoot *sigh*. It seems dead bodies aren't enough, someone get a decent photo, please....!
