they have mentioned hair tech for some time that never seemed to materialise. the original hair they had just did not look good enough so they needed to make new tech for it and then we heard nothing more. that was about a year ago.
its possible CBS said to leave it as it is. the whole 'is the cartoon canon' is fuzzy and they may want the females to look like the male seen briefly in star trek IV rather than the cartoon female.
I've been pondering this also. In fact, I think that's my main reason for not having bought that species from the C-store. That's the only species I don't have unlocked (besides Liberated Borg) because they look wrong without hair.
There should be an option for a mane or no mane, regardless of gender. Also, since it is possible to scan a person into a computer and create a wire frame of that person, why can't a lion with a well developed mane be scanned, and use that as the template?
Fun Fact about the "New Hair Tech": It isn't completely ephemeral. Ever take a look at the targ fur on the KDF Vet Shoulders? It was claimed, some time ago, that it is the result of the New Hair Tech. Sadly, as evidenced from virtually every furry creature added to the game since, that the Tech hasn't been further utilized, which might not bode well for Caitian hair.
