A terrifying cat had come to live in the big house. Every time the mice went into the kitchen for a nibble, the cat would send them scampering.
"We'll starve!" they shouted, and decided to have a council meeting. One by one the mice spoke, but no one could think of a plan.
Finally, a boastful mouse stepped forward and proclaimed his idea to be best. He explained, in detail, how a small bell attached to the cat's collar would warn them all of his approach.
