Caitians are a sapient feline-humanoid species that hail from planet Cait, located in the Lynx Constellation. 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 23th century, Cait is a members of the United Federation of Planets. The Caitians' Starfleet uniform doesn't seem to require footwear, as is the case with Megazoids.
