The mice, once called a meeting to decide on a plan, to free them of their enemy, the 'cat'. At least, they wished to find some way of knowing when the cat was coming, so they had time to run away.
Indeed, something had to be done, for they lived in such constant fear of the cat's claws that they hardly dared stir from their dens, by night or day.
Many plans were discussed, but none of them were good enough. At last, a very young mouse got up and said, "I have a very simple plan, but I know it will be successful. All we have to do is to hang a bell around the cat's neck. When we hear the bell ringing, we will know immediately that our enemy is coming."
All the mice were much surprised that they had not thought of such a plan before. But in the midst of the rejoicing over their good fortune, an old mouse arose and said, "I will say that the plan of the young mouse is very good. But let me ask one question, who will bell the cat?"
Moral of the story: Some things are easier said, than done!
