Man-Kzin Wars IV is a collection of short stories set within the Known Space universe. The stories within take part during the Man-Kzin Wars and recount some of mankind's dealings with the alien species known as the Kzin. 
"Welcome to the hottest pocket in Larry Niven's Known Space: the time of the assault on pacifist humanity by berserker felinoids from the planet Kzin. This time humanity's representatives to the Warrior Race are Donald Kingsbury, Greg Bear, and Steve Stirling. As is traditional in this war for species survival, in all cases "monkey cleverness" (i.e., human cunning) is more than a match for felinoid ferocity. But as is also traditional, victory never comes cheap to those out on the sharp edge of The Man-Kzin Wars."
- The Survivor by Donald Kingsbury: Tells the story of Eater-of-Grass, a cowardly Kzin who survives against all odds in the brutal environment of the Patriarchy and through the bloody Man-Kzin Wars to become the respected Trainer-of-Slaves
- The Man Who Would Be Kzin by Greg Bear & S.M. Stirling - Recounts a mission against the Kzin using a human Telepath to infiltrate the ranks of the enemy posing as one of their own.
