We can go for more than a few days, if you like. Set it so Lyla feeds them while we're gone? Maybe leave the door open so the cats can wander. There's no way Mouse is letting you go out the door without him, you know it. He's nanny dog to the rescue.
Don't tell Mister I told you, but he's become an 'indoor' cat, and is used to life without bugs. The claws are so he doesn't give himself away.
And of course Harri is going to want to go and play princess science. So all her princess dresses will have to go with us.
