Just a simple edit of the furry/cat skins from genensims.com that I did several months ago. I added nose, ear, and lip details in appropriate shades for the following eight skins. None of the sims pictured are wearing makeup. All of the body details have remained the same.
(I actually did add a lip texture to the black fur skin, it's just subtle. I wanted to keep it black because none of my black cats have pink gums. :-P)
