    Just like birthmarks, animal markings come in all sorts of shapes and sizes. Luckily for them, their spots are a million times cuter than a pasty patch on a human's body. We've rounded up some of the coolest specks and smudges found on our little animal friends.

    GHOST'S GOT HIS BACK

    No one dares to mess with Casper the dog. Why? Perhaps it has something to do with the ghostly ghoul floating on his all-black back.

    BEAR HEAD

    This cat has always got something on its mind. Its owner can't quite figure out if that marking looks more like a koala or a giant panda. You decide.

    TWO-FACED FIDO

    When people first meet Jim the Foxhound, they often wonder if half of his face is painted like a jester. But the joke's on them. Jim was born with a unique face that really makes him super special and a standout at the dog park.

    Although her marking is pretty precious, it's not ideal. Kitler the kitten, small enough to fit in a cup, has a strong resemblance to Adolph Hitler. She was finally able to find a home after being found abandoned at the side of a busy road.
