My cat goes out at in the day but then mummy locks the door at night so how can my cat get back in the house I wonder . Maybe he has super powers and flies to the window and unlocks it or maybe he can walk through walls. He could go down the drain pipe but how could he be so clean when I wake up. I have told my cat a million times “How do you get back in the house ” but he will never tell me he will just “meow”. When I think about it he could just come through the cat flap!
