Cat on a cliff

I've heard of a cat in a hat. I've heard of a cat on a hot tin roof. But I've never heard of a cat on a cliff. I went up to Birsay and, as the tide was out, walked over to the brough. I headed around the cliffs and saw the usual birds- puffins, guillemots, black guillemots, gannets, etc. but I was very surprised to see this cat snoozing on a ledge of a high cliff. It was a bit of a sun-trap and out of the wind so quite a nice spot. It is probably a feral cat living on the brough on mice, rats, young rabbits etc. Here are more shots from the walk: https://www.flickr.com/photos/octobermoth/
