What I find particularly ironic is how they mention in several older lore sources that the Ohmes (and I guess Ohmes-Raht to some extent) are the most common subspecies of Khajiit in the other provinces due to their visual appeal towards man and mer. Don't know why Morrowind and Oblivion are full of the more bestial species, then. I guess for distinction.
In MW, I can see the more beastlike being there because of a dunmer's hatred towards furries. The more beastly the thing is, the more you really don't have to give a 2 cents about because it's not even merish/human/w.e.
As for OB, they probably wanted something no so human looking to have some distinguishable difference between the other races (har).
