We moved into our house in Sept 22. Previous owners has cats that went with them and last week one of them appeared at out door. Very familiar with house extra and then discovered he'd previously lived there. Never shown up before. Back again today. Owners moved about 2km away so not to far and not quite as far if you come across the fields which I suspect what kitty does. Owner is asking what can she do to stop him. I have no idea. I did tell her today that we wouldn't encourage him by feeding him or letting him in but what else can she do. I mean it's 19 months since we moved and now he shows up. I don't mind but what she do?
