They were the Forest People and they were changed into khajiit by Azurah. The Forest People are also who the bosmer come from, instead being changed by Y'ffre.

Who are the Forest People? That's hard to say, but after running through AD quests in ESO I'm going to have to say that they are the Aldmer that lived in the southern ever changing forests, and like the land, they too had no form.
