I can't remember the exact wording and don't have the book at hand, but the FASA backstory says that the Caitians stopped eating meat once they achieved civilization. Eating meat gradually became taboo, a reminder of animalistic, uncivilized times.
It's the classic Trek "species denying their true nature" thing. It went on to say that some Caitians still did eat meat, but I imagine they get the V'Tosh K-whatever treatment.
I'd imagine the Caititans could use various supplements to survive on a vegetarian diet, but I'm reminded of the Futurama episode with the popplers ("we taught a lion to eat tofu!" - cut to really sick looking lion).
