Posted on another thread but relevant to this one -
Ive no doubt that there are the odd escaped / released cat around. But I don't buy that there are breeding populations. Whats interesting is that pretty much every time one is seen, its always by someone on their own, and some 'civilian' (don't take offence). Ive spent many years and 1000's of hours, in the countryside both day and night, seeking to hunt out beasties from the woods, hedges, bracken, gorse, ditches, forests, moorland, you name it. Ive pretty much tracked down and often ultimately killed (when legal and for a purpose) pretty much every quarry in the British Isles, and many across Europe (the dogs have passports!). This includes all of the usual ones, fox, rabbit, hare, deer of every variety, wild boar, badgers in Europe where it is legal, and a few weird ones, like wallabies (they were not killed). And never in all of that time, have I treed or flushed or caught a large cat in the U.K. And never in all of the hours and hours, they I have spent walking / driving around fields at night with a lamp or night vision have I stumbled across one. And funnily enough neither has any other hunter in the whole country. . . . nor has any of the countless packs of hounds who hunt nearly every moor, wood and field in the U. K over the winter ever treed, flushed or killed one. No game keeper has seen one, no deer stalker sat in a high seat silently for hours. . . . .
It's always some random walker, or someone just having a potter about that 'bumps' into one quite by accident.
So why is that?
And please don't tell me that cats are too smart or cunning or any of that crap. As I have plenty of friends who live in countries where there are big cats (of varying types) who regularly hunt them, and successfully tree of catch them. And they don't seem to be smart enough to avoid the random walkers etc who see them.
