Very informative article, if you're not using it in some kind of recipe i guess you can feed it raw just by itself or mixed with wet food but very little amount, i use one raw egg yolk in a raw diet mixture that last 8 days or more.
My babes get whole raw egg as an occasional treat, without problem. Don't worry about the white. After all, a feral/wild cat would certainly not leave the white and just eat the yolk! My cats just get their eggs cracked into a bowl, my dogs get a whole egg to play with - a 'breakable ball'
