Moppet and Mittens have grown up into very good rat-catchers.

They go out rat-catching in the village, and they find plenty of employment. They charge so much a dozen, and earn their living very comfortably.

They hang up the rats' tails in a row on the barn door, to show how many they have caught—dozens and dozens of them.

But Tom Kitten has always been afraid of a rat; he never durst face anything that is bigger than—

A Mouse.
