The term felinoid is descriptive of a species that evolved from feline origins, and retain cat-like physical traits as opposed to primates, who followed a primate evolutionary pattern, or insectoids, who are descended from insects.
There are four known species that are felinoids:
- Caitians, (TAS)
- Kzinti, (TAS: "The Slaver Weapon")
- Vedalans (TAS: "The Jihad")
- Lyrans (Starfleet Battles race distantly related to the Kzinti)
The word "felinoid" has not been mentioned on screen, but has been used in various background and production materials.
