That's very cool! I know there is one person on here who's mother's cat has a heart on his chest. (At least I think it is a boy, so sorry if it's not)

My girl cat has a distinct "lightning bolt" down her nose.
You can see her in my "pics of kitties" post here in Cat General.
Sorry, I tried to copy it here, but I am just not doing so well with the computer lately.
