Got home tonight and there was a note behind the door saying "give me a call about the cat".
About five years ago he turned up on our doorstep and gradually wormed his way in to the extent he has his own chair and favorite spot to sit, knows when our car turns into the street, and in the past month has been staying all day.
Now they want him back.
Ended up carrying him up the street to their house hoping he might get the message. He's not been back................yet
