What a beautiful cat! If it's any consolation, my mum's young cat, Archie, went missing last Thursday (she started a thread on here too and had a fab response from people), and he turned up completely fine and acting as if he'd never been away on Tuesday having caused us SO much worry! I presume you've contacted local vets etc? Lomax on the top of Lordship Lane are very good, and it might be worth letting the pet shop on North Cross Road know as well...? Best of luck with your search - I really feel for you, and know how worrying it is, but I'm sure she'll turn up unharmed soon x
