Alien Species

Caitians are a sapient feline-humanoid species that hail from planet Cait, located in the 15 Lyncis system. They are easily recognizable by their fur covering, cat-like facial features, digitigrade posture and a long, flexible tail.

The Caitians are evolutionary relatives of the Kzinti, the relationship between the two races being comparable to that of Vulcans and Romulans. As of the 23rd century, Cait is a members of the United Federation of Planets. Like the Zeosians, the Caitians' Starfleet uniform doesn't seem to require footwear.

In the past, Caitians used to hunt Betazoids for food.

  • In the Kelvin timeline (depicted in the 2009 film Star Trek and its squeal Star Trek Into Darkness), two characters referred to as Caitians appeared more Human-like in appearance. There is the possibility that these are examples of Caitian-Human hybrids.
