Hia - have you tried registering him with http://www.animalsearchuk.co.uk/find-los...ch=1&lfp=0

Also East Dulwich forum?

I found a cat recently who had managed to get herself across Stansted Road but hadn't wanted to cross back over. Turns out she'd been missing for quite some time (I found an old 'missing' ad for her on the above website and got her back to her owner). A similar thing happened to a friend of mine's cat regarding crossing a main road so it may be that ginger has wondered from Dulwich or other side of Crofton Park?

Nice one for looking after him and for doing the right thing!

cheers
