New cat on the block!

I could not believe the cheek of the neighbours new cat. It actually dared to come onto my sun terrace! ............And I know it's been using our plant pots as its toilet at night when I'm not around to scare it off. Anyway, I glared at it through the doors. And then, when I was quite sure it had gone away, I raced outside and stood guard just incase it came back??!! You can see it on this photo, right at the end, on its own bit of the wall!
