Some people have characters that are dunmer/khajiit.
As for khajiit hybrids, though lore doesn't truly support them, only the Zeterra family has obvious hybrids.
Aw, you guys're talking about me, huh?
As for Khajiit.. erm..
loving, they're debatable in reality, but I assume that some kinds can. And I doubt they shed all
that much. Though the idea of a man getting caught cheating because his one-night-stand left some of her fur in his bed
is an amusing thought. Heh..
Anyway, Argonians, because of their nature of being coldblooded, are generally accepted as being unable to breed with other races. As for their busts, TES3 is the only game to my knowledge to have them without (I know Arena has them for the scaly females, so it's not just Beth lazies in OB), so I can only assume them to be some odd sort of half reptilian half mammalian, with exception of the Morrowind variety.
