Cat sitting

My friend Helene, and her husband, have gone to Wembley for the Manchester City game so I have been cat sitting today.
They have four cats, three black and one black and white. I can still not tell the black ones apart properly so not sure at any time which ones are in and which ones are out.
I couldn't manage to get all four in one picture so I have blipped them all separately.....
well at least I think I've blipped them all.... It's so hard to tell.
