You're playing a human wearing a cat mask.
Kaijiit and Argonians walk differently and can't wear human boots. They are beastmen. Not humans wearing a Halloween mask.
Actually, while I'll grant you the "walk differently" part, I was deliberately not putting boots on my Khajiit. Granted, I gain absolutely nothing for doing so (in fact, I'm shutting myself off from a few of the Light Armor/Heavy Armor skill tree bonuses which require a
full set of armor, boots included), but hell, I feel like it.
...can't say as I'm going full
Morrowind-style, though, because A) I haven't played
Morrowind to compare (it's on the agenda at some point) and B) I'm wearing headwear, which IIRC
Morrowind Khajiit couldn't do(?).
(...also,
Arena and
Daggerfall Khajiit were basically entirely humanoid, down to having pretty much no fur, right?
Morrowind Khajiit are the only ones I know of with the digitigrade feet thing, barring mods.)
