I have twice in the past week seen a cat that looks like the photo (but I'm no cat expert- looks like as in long haired and b/w and friendly) in Rockbourne Road. The kids and I tried to stroke it, and it came when we coaxed it, but had a very distinctive way of lowering its back when we tried to touch it: I assumed it had arthritis or was sensitive somehow. Maybe yours? Best of luck, anyway.

N.B. I've been using Rockbourne Rd twice daily in the week since January, and haven't seen this puss 'til recently, so I hope you're successful.
