So our cat, 2 years old, has only been coming home for food and then leaving straight away. This has been going on for a couple of months, maybe more. We have finally identified where he's been spending his time, in someone's flat from another nearby road. They don't have a cat themselves so they've been opening the door for him and giving him treats. 'We'd be willing to keep him' they said. We've just brought him back but he quite clearly doesn't want to be here.
