Spotted - lost looking cat, Colyton Rd

[Belle]

We were followed from Nunhead all the way down towards Forest Hill Rd by a little black and white cat (poss kitten?). Very friendly, no collar. Three in our household highly allergic so we couldn't take it in, and it wandered towards our neighbours who kindly offered to keep an eye on it, tho it may have just carried on. Here is a pic. First encountered on Cheltenham Rd.
