Nemo on the Roof

It’s early Saturday morning, I look out of my kitchen windows – but what’s that?
It the neigbours' cat, Nemo, sitting on the roof waiting for his human parents to get up and let him in.
Our neighbours live on first floor, so they cannot hear their two cats at the door, therefore they have built a cat-ladder. But it is not every day you see a cat on a roof. :)
