Wayne, you are right, there are not any big cats native to the UK and any that are here must have been introduced at some time. In fact there is a lot of argument as to whether there are any at all! I became interested when one was seen close to my home (I know the man who saw it and know that he would no way make up a story like that), I researched the subject a bit and found that there have been many many sightings over the years all over our country by many sincere people. I for one am convinced they are out there.
