non-canonical, and the story is incompatible with Juggler of Worlds, which is co-authored by Niven and Edward M. Lerner. Conversely, Niven's story Fly-By-Night refers directly to, and summarizes, the events of Telepath's Dance, so it appears he considers that story canonical. The canonicity of other stories in the series is undetermined. Many of the stories in the series have added details to Known Space and its history, details which may be incompatible with older stories in the canon (in particular, those written by Niven long before the Man-Kzin Wars series was published). The protagonist in Matthew Joseph Harrington's Teacher's Pet from Man-Kzin Wars XI, who has become a protector after landing on Home while fleeing from Kzinti, deduces several things that (at least at first glance) seem to be at odds with accepted canon - for example, that Puppeteers had been manipulating both humanity and the Kzin far more than anyone had previously thought. In other cases, stories clearly contradict established canon. For example, various MKW stories state that Kzinti did not establish their own interstellar empire nor invent their own spacefaring technology. Instead, primitive Kzinti warriors were hired as mercenaries by the Jotoki, a species of interstellar traders, whom the Kzinti later overthrew and enslaved. Yet, Niven's "The Soft Weapon" states: There had been a time, between the discoveries of atomic power and the gravity polarizer, when it seemed the Kzinti species would destroy itself in wars. Now the Kzinti held many worlds, and the danger was past. However, "Jotok" suggests a possible compromise scenario. In that story, primitive Kzinti clans on the Kzin homeworld are being marginalized by advanced Kzinti who use atomic power and gravity polarizer-driven spacecraft. It is the primitives who are hired by the Jotoki, to use as mercenaries against the more advanced Kzinti.
