What could be easier than looking after a neighbour's cats? You have to remember their food, when to let them out and you hope that they will come back home again. But what do they do when you have gone away? Do we find out what they do or even what they think about? Once outside they are free to do whatever they like and that is exactly what they will do! Cats are secret creatures, with eyes wide open and whiskers stiff. Unless you speak 'cat', you will never know what they do or what they are thinking, and they will never tell you.
