As you can see near the upper right of the photo, the green door to the studio was locked. My thought was that maybe this cat was waiting for the studio to open, in hopes that the owner/operator might set out some food and water for him (this would not be at all surprising). Or maybe this guy was just resting for a while, plotting his strategy for the rest of the morning, or daydreaming about the mouse that got away, etc. Who knows?
Also, I was tempted to clean this guy up a bit in Photoshop, but then decided against it. The cat has bits of white/gray hairs mixed in with his black coat, dirt and sand on his face, and other 'beauty' issues that are so typical of the stray cats of Greece. Some are in really great shape, and others look pretty rough around the edges. This guy was in between, but still photogenic enough for me.
