Guess what?
My "found" cat had been with us for 2 weeks, which means he could go up for rehoming. His owners had not come forward
Just before he was put up for adoption, we decided to advertise him one more time & guess what ~ at the very last minute his owners came forward. Yipee ~ they came to see him & were really pleased that they had got him back. It turns out, he's such a happy chap, that if someone says hello to him, he follows them, which is exactly what happened when he was found.
He has gone home now & is going to be microchipped
