Amarillo Design Bureau has — as part of its license for the Star Fleet Universe series of games — incorporated many aspects of The Animated Series into its works, not least being the inclusion of the Kzinti, although in a modified form.

Star Trek: Enterprise producer Manny Coto has commented that had that show been renewed for a fifth season, the Kzinti would have been introduced.

Starship designs were produced which closely resemble the Kzinti / Mirak ships from the Star Fleet Universe, a gaming universe that includes the boardgame Star Fleet Battles and its PC analogue Star Fleet Command.

The Kzinti were initially introduced in Niven's story " The Warriors " ( originally in Worlds of If, 1966 ) and " The Soft Weapon ", ( 1967 ), both collected in Neutron Star ( 1968 ).

The Kzinti also appeared, along with allusions to slavers and stasis boxes, in The Slaver Weapon, an episode of Star Trek: The Animated Series written by Niven, as a proud and carnivorous species.

Manny Coto, who produced the final season of Star Trek: Enterprise, had made plans to include the Kzinti in an episode called " Kilkenny Cats ", but the series was cancelled before this could occur.

The Kzinti were incorporated into the Star Fleet Universe where they became a powerful empire known as the Kzinti Hegemony, mortal enemies of that universe's Lyran Star Empire-although it is alluded that the Kzinti and Lyrans share common ancestry, a claim both sides violently reject.

In the Star Trek Logs written by Alan Dean Foster, it has been hinted that the Caitians are an offshoot race of archaic Kzinti ( where both genders are intelligent ) who have renounced conquest.

According to a memory of Lieutenant M ' Ress, secondary communications officer in the Star Trek Logs, the Catian and Kzinti languages are similar enough that M ' Ress can pass as a Kzin just long enough for her to send off a distress call from a Kzin raiding ship.

The name of the Tzenkethi, mentioned in Star Trek: Deep Space Nine, was rumored to be an almost-anagram of " Kzinti ".

Had Star Trek: Enterprise not been canceled, the Kzinti would have appeared in the fifth season.

The instruction manual for the PC game Star Fleet Command clearly refers to the Kzinti by name in the background story for the rival race, the Lyrans.

This race is introduced in Star Fleet Command II: Empires at War by simply changing the Kzinti Hegemony to the Mirak Star League.

Unlike the mainstream Star Trek universe, Star Fleet Battles seems to consider some, but not all of The Animated Series, as being a canon material source, thus leading to the inclusion of aliens such as the Kzinti, which had originally been created for a non-Trek story series.

In the fictional Star Fleet Universe, the Kzinti Hegemony is a powerful stellar empire violently opposed to the Lyran Star Empire and allied with the Hydran Kingdom and eventually with the United Federation of Planets and the Gorn Confederation in the General War.

Developed over the last two decades and more as an expansive development of the background as supplied in the Original Series as well as in The Star Trek Star Fleet Technical Manual, the Star Fleet Universe introduces a range of new races and storylines ( such as the Interstellar Concordium and the General War ) as well as drawing from the Animated Series for inspiration – a modified version of the Kzinti are a major part of the SFU, for example – unlike the Paramount universe.

Many of Niven's stories take place in his Known Space universe, in which humanity shares the several habitable solar systems nearest to the Sun with over a dozen alien species, including the aggressive feline Kzinti and the very intelligent but cowardly Pierson's Puppeteers, which are frequently central characters.

* The Man-Kzin Wars: A shared universe based on the Kzinti Conflicts in Larry Niven's Known Space universe, featuring writers personally selected by Niven

The Kzinti are the first on-going alien contact that humanity has met within the Known Space universe.

One of the alien races that inhabit this universe are the Kzinti, a larger-than-human feline-based biped with large membrane ears, a cylindrical torso without a spine, and large fangs and claws.

Vulcans are repeatedly stated to be herbivorous in the TAS episode " The Slaver Weapon ", by the carnivorous Kzinti.

The Kzinti call themselves " Heroes " or the " Heroes Race " and because they believe themselves to be " heroes ", their society places a very high value on " acting Heroic " and behaving in a heroic fashion.

Following their return to Known Space, he is given the name of Chmeee ( the " ch " is pronounced like a guttural German " ch ", as in " ach ") and given breeding rights by the Kzinti Patriarch.

The first Man-Kzin War ended when the humans obtained the faster-than-light drive ( FTL ) from the Outsiders, after which the Kzinti ships stood no chance against the FTL warships.

Several of the stories of the Man-Kzin Wars depict the nearest Human colony at Alpha Centauri, called Wunderland, which was occupied by the Kzinti for over 50 years.

The Kzinti reappear in the comic The Wristwatch Plantation, also by Niven ( and which included the Bebebebeque from his Draco Tavern stories ).

After several battles, the Patriarch and the Usurper ( as the Kzinti histories call them, it is not certain which of the nobles is which ) lead their fleets in a direct battle against the other.

The War of Return swept through Kzinti space as various commanders were faced with a decision as to which side would win — or reward them better.

It was used as a military outpost by the Kzinti, until the planet was hit by a weapon called the " Wunderland Treatymaker " during the Third War.

The Kzin civilization was at an iron-age technological level when an alien race called the Jotok landed and made stealthy First Contact with a tribe of primitive hunter / gatherer Kzinti.

The Puppeteers had hoped that the culling of a quarter to a third of the more aggressive members of the Kzinti with every war would result in a more peaceful race, or at least one that was capable of coexisting with other species without instantly trying to kill and eat them.

At one point, Louis Wu, while visiting the Kzin homeworld and given access to the Kzinti Patriarch's game preserve, was confronted by a young Kzin and his father.

Their race was formerly subjugated by the Kzinti until freed by the humans.

This was a mechanism to cause rapid Kzinti evolution, since the most aggressive Kzinti would die in battle, leaving the more docile individuals to breed, eventually suppressing their racial instinct for aggression.

In the fictional variant of the Star Fleet Universe as represented in the games Star Fleet Command II: Empires at War and Star Fleet Command: Orion Pirates from Taldren, the Kzinti Hegemony was named the Mirak Star League, with the species Kzinti renamed for SFC to the Mirak.

He was the one that caused the most damage to the Ringworld village of Zignamuclikclik and were he not a part of the Docile Kzinti project, he probably would have leveled the village to the ground.

" written around it in Kzinti script.

By the time Ringworld takes place, Kzinti are able to deal with other races diplomatically, rather than by attacking and enslaving them.

They never saw the stars until they were enslaved by the Kzinti.

It is inhabited by a number of different evolved hominid species, and includes representative samples of Bandersnatchi, Martians and Kzinti, and possibly other alien races that existed at the time of its construction.

The world is often known as Kzinhome by the Kzinti themselves.

Kzinti cubs are tested by the Black Priests.

Kzin society explains this by stating that the Fanged God removed Kzinrretti's souls as punishment for an attempted rebellion against him shortly after he created the Kzinti.

The net effect of these wars is summed up by a retrospective comment from Beowulf Schaeffer in the short story " Grendel ": " The Kzinti aren't really a threat.

With decreasingly impressive logistical and technological advantages, each Man-Kzin War results in the confiscation or liberation of one or more Kzinti colony planets by the humans.

From the Kzinti point of view a Manrret's stamina, speed, reflexes, pain tolerance, and reasoning capability ( enhanced intuition by virtue of increased interconnectedness between the left and right halves of the human female brain ) are far superior to a Man's.

The Kzin homeworld is called " Kzin " by all other races save the Kzinti, who call it " Homeworld " or " Kzinhome ".

They started a series of wars ( the Man – Kzin Wars ) between the warlike Kzinti and humans, and guaranteed that the Kzinti lose each time, not least by using a starseed lure to guide an Outsider ship into human space, introducing faster-than-light travel to humanity.
