Not our cat

This is Flophouse. It's not his real name, but we call him Flophouse because that's what he treats our house like. Comes in when he fancies. Eats any of our cats' food they've left. Sleeps on the comfy chair by the radiator. All very nice. Then we don't see him for weeks, till bold as brass there he is coming through the cat flap.

Our three useless cats seem powerless to stop him. In fact, I think they're friends, Flophouse stands outside the front door and miaows for them to come out and play.
