Then again, three meters would be perfectly fine for one of Larry Niven's felinoids. And three meters is basically what we get for Trek's onscreen take on the Kzinti, too:

M'Ress being the only onscreen example of Caitians is a great excuse for postulating that she's just a wee kitten as far as her species goes. And if a source presents Caitians as an offshoot of Kzinti (like the FASA sourcebook does), then onscreen evidence is very much on the side of the 2-3 meter height range.
