 The Kzinti were incorporated into the Star Fleet Universe where they control 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.The Kzinti are also represented in the lore of the Star Fleet Battles universe tabletop gaming system, with a number of scenarios and starship sheets devoted to them.The "Star Trek Log" series, written by Alan Dean Foster, hint that the Caitians are an offshoot race of archaic Kzinti (where both genders are intelligent) who have renounced conquest.
