Missing: small Siamese-coloured female cat, Osbaldwick, York

Sylvie has been missing from Heather Bank, Osbaldwick since 24 April. Cream/grey body, black/dark tortoiseshell face, ears, paws and tail. Blue eyes. Neutered and microchipped.
Although she has the colouring of a Siamese, she is a (very) mixed breed and is the shape of a normal moggy. She is friendly but shy of people she doesn’t know. She doesn’t normally go far so worried about her and appreciate any help to get her home.
