The book The Three Musketeers comes in the mail. It is much larger than we expected. Early the next morning there is a strange, fluffy orange cat on the fire escape looking in the window. Its eyes are wide and frightened. We think it is just a strange cat passing through. It leaves the windowsill. But then another cat, this one gray and fluffy, comes down the fire escape. It, too, gets onto the windowsill and looks in the window. It has lighter gray tufts sticking out of its ears and is not frightened. We think that they are two young cats exploring the neighborhood. It leaves the windowsill. Then a third cat comes down the fire escape. It is fluffy and black. It does not get on the windowsill, but goes on down after the others. For a while, the three cats stay in the yard.
