Offering a bowl of milk
As you can see, there’s a lot missing yet: Some colours have to be filled in (the rest of the wall, the sky), the lettering has to be done, and the human and the street lack shading. I am not quite sure about the colour contrast yet – the street may have to be much darker. In order to decide that, however, the wall has to be finished.
This scene has its place at the beginning of the story, after the cats have come to the village in order to hunt mice and rats. They haven’t met any humans yet. One day, one person overcomes her fear and goes out in the street with a bowl of milk, offering it as a sign of good will and friendship.
