Lost b&w cat (mostly white) around Dulwich Common

[S]

Could you keep an eye out for my parents' black and white cat, Sam, who went missing from 8 Dulwich Common last night? He is big, mostly white with bits of black, and has a skeleton-style face. He's about seven years old and is microchipped, no collar. Has quite a noisy miaow.

My parents are on 0208 693 1946. He may have gone to the allotment or somewhere nearby. (Or my mobile is 07841904613).
