💬 Owner's Message: "Hi, my much loved cat, Bailey has vanished. He got out around 10:00 Sunday night and I have not seen him since. Bailey has never stayed out all night before, and usually sleeps curled up across my legs, so I am very worried. His brother is also very distressed at not having his cuddle buddy
He is a 7-year old, neutered domestic shorthair. Bailey grey with a grey upper face and white jowls, with a white diamond running up from his nose into his forehead. He has a white belly. His right front leg is white and his left front leg looks a bit like Bailey’s Irish cream with dark running through it. He is chipped. That number:91330
He is a little afraid of strangers and probably won’t let you pick him up.
If you see him, could you please call or text me at.
Thank you very much. Fingers crossed!
Jane-Michèle
