No kidding! But since their form is decided by the lunar cycle, and thus be pretty reliable to foretell, one would expect them to favor their own form? Suthay-raht parents would most likely want Suthay-raht children, i mean.
Maybe, maybe not
. The http://www.uesp.net/wiki/Lore:Pocket_Guide_to_the_Empire,_1st_Edition/The_Elsweyr_Confederacy suggests that "in their own society at least, no one of them is more important or inherently better than another", though obviously as with all in-game lore that may be the ignorant/partisan view of a character, not what the developers who dreamt up the Khajiit thought. It would certainly be more
interesting if the Khajiit simply accepted whatever form their children took, and formed whatever relationships worked for them (emotionally, physically, tribally).
