I'm not a big fan of the Caitians and confused as to why they were even introduced. Nevertheless, I was intested to know if they appeared anywhere else than whet is mentioned on the Wiki
page
Known appearances ...
- Animated series
- Star Trek IV : Voyage Home
- The cantina
I'd much prefer a Dog race (think John Candy as Barf

)

In fact, I've always found it werid that most of the aliens were humaniods, leaning towards human appearance instead of more animalistic appearances. on the TV series they used human actors, so they were a little bit limited by that. however this is a game, so we should be able to have more inhuman features, like having four eyes litterally.
