The mice once called a meeting to decide on a plan to free themselves of their enemy, the cat. At least they wished to find some way of knowing when she was coming, so they might have time to run away. Indeed, something had to be done, for they lived in such constant fear of her claws that they hardly dared stir from their dens by night or day.
“I have a plan that seems very simple, but I know it will be successful. All we have to do is to hang a bell about the cat’s neck. When we hear the bell ringing we will know immediately that our enemy is coming.”
It is one thing to say that something should be done, but quite a different matter to do it.
