Lost tortoiseshell cat

[TessaB]

My short haired tortoiseshell cat, Groovy, (photo attached) has been missing since yesterday morning. We're on Kings Grove SE15, so I imagine she will be around the area of Kings Grove and Asylum road. She has a tortie body, white stomach and feet and a black smudge on her nose. She is quite small, just a year old, and can be shy with strangers, but is chatty. She usually comes back from her explorations when we call, so I think she might be shut in someone's shed. She is chipped. Please can everyone check their gardens and sheds and let me know if you see her.
