Watcher on the wall

Took a walk up the road, had my cats come too, can't be the only one to take their cats for a walk!!
I started with four but only two got as far as the corner I turned and came back from. I saw loads of things to take shots of for today's photo and took a load, but when I downloaded them this one stood out. Smokey is framed and poised, watching something, I couldn't work out what. She stood for about a minute before moving off and jumping down, I think she looks fab!
