We got a 3 year old male cat last Sunday as his owner is emigrating. He stayed indoors all week and took his time getting to know us but went outside yesterday and promptly disappeared. He's been gone for 24 hours and I've been outside, back and front, calling his name and shaking his biscuits. No sign at all. I'm really worried and just wonder if there's anything else I can do. Should I leave some food outside? I thought I should maybe open out back gate, although he can get back into the garden from other gardens, we're in a terrace. I feel so stupid as I think I should have kept him in longer but he was off like a shot yesterday. Always went outside with his previous owner and mainly at night. Any suggestions gratefully appreciated.
