This is an awesome thread.
For educational purposes, I'd like to post two results where you can see what I was going for, and that I didn't get it, but that the result was gorgeous in a different way:
Here, I was trying to shuffle some traits around on a line of solid white cats (Russian white, white whiskers, crystal clear eyes) and these guys both happened to throw their hidden fur, but keep the white eyes and whiskers, and I love it:
Here, I was trying to get huckleberry eyes on a Tiger! Huckleberry (you will note that most of my contributions to this thread will be of the matchy-matchy variety). It didn't work, but throwing the hidden flame fur AND flame whiskers, and getting the huck eyes, plus an ear that shows off the flame fur, was a really striking combination that I like but wouldn't have thought to try for on purpose.
