Caitian

Caitians are a species of feline-humanoids native to Cait (Regulus V) but have settled a number of colony worlds.

They made first contact with the Orions and the Ferengi, and met Federation ships for the first time in 2249. Within a few years, such good relations existed between the cultures that they entered the United Federation of Planets.

Caitian names do not follow a gender pattern, so no name is distinctively male or female. (RPG: Star Trek: Roleplaying Game Starfleet Operations Manual


 * Due to copyright issues, the Unicorn RPG novels are not able to use the term "Caitians", so they have used "Regulans", but it is implied that they do mean Caitians.
