Many of us here at Vetstreet are fascinated by pets who have unique coats and cool shapes hidden in their markings. So we asked our Facebook fans to share pictures of animals that have interesting coloration, and you did not disappoint. From mustachioed cats to a horse of a different color, here are our 13 favorite photos of pets with cool coats.

Dark Moon is the perfect name for this chimera cat. Another great name for the kitty would've been Two-Face.

Look closely and you'll see the white butterfly on Bear's chest.

We love the wild-looking spots of Bengal cats — and Mylo wears them well.

Lily has an awesome heart on her side and an upside-down flower on her bottom.

Brodie the Border Collie mix's black smudge around the eye is just classic.

We love that JR is dark brown in the front and white in the back. His owner says, "He's just a baby and the light of life. Oh, and he's a cheeky boy!"

Duchess here mustache you a question.

Molly, a 10-year-old Blue Heeler-Australian Shepherd mix, has a perfect heart on her side.

Sahara has a calico face, but one side of her body is tortoiseshell while the other is just black and white.

How cute is this brindle Pug-French Bulldog mix?

Gino's human says, "This is my blind boy, Gino (on the right). Gino has half of a Charlie Chaplin mustache, a crooked 'part' in his black 'hairdo' and an all-black tail that looks like it doesn't belong to him."

Meeko the merle dog is so photogenic — no Instagram filter needed.

And last but not least, we could never leave out Marble the top hat-wearing guinea pig!
