The Man-Kzin Wars I

Once upon a time, in the earliest days of interplanetary exploration, an unarmed human vessel was set upon by a warship from the planet Kzin—home of the fiercest warriors in Known Space. This was a fatal mistake for the Kzinti, of course; they learned the hard way that the reason humanity had given up war was that they were so very, very good at it. Thus began the Man-Kzin Wars. Now, several centuries later, the Kzinti are about to get yet another lesson in why it pays to be polite to those hairless monkeys from planet Earth.
