This existentially sitting kitty is aparently doing an excellent job of herding humans through an old Welsh landmark. "Despite the name ... St Dogmaels," puns the photographer, "they've employed a cat as official tour guide. After having returned some other visitors to the exit, the guide sat posing on this wall until I'd taken its picture, and then showed us round the whole abbey, pointing out places of interest, such as the medieval water supplies, ovens, and the church itself. Then it led us back to the entrance and went back—no doubt ready for the next customers!" No matter where one might find oneself these days, it's always a good idea to sit near the exit. This particular black cat looks both reasonable and calm, and most likely isn't superstitious about so many tourists crossing its path each day; however, I wouldn't push your luck. Turn off your cell phones, don't use flashbulbs, keep it to a dull roar, and try not to step on anyone's tail. There were 16 cases of Exisit* in OhioLINK today, and 684 in WorldCat.
