Two-faced cats are also known as Janus cats after the mythical Roman god of beginnings and transformation, who had two heads as well.
If you have a cat that is expecting, it is extremely rare that one of the kittens will have two faces. But it can happen, as it happened few times before.
The disorder is called Diprosopus (in Greek it means two faces) or craniofacial duplication and can cause part or all of an individual's face to be duplicated on its head.
Affected kittens usually die within few days after being born.
Two-faced kittens include:
Harvey Dent – born on 31 January 2012 in Florida. He seemed to be healthy, but died in two days
Tiger – born on 12 July 2006 Grove City, Ohio. Gone missing two days later
Gemini – born on 12 June 2005 Glide, Oregon – lived four days
According to my research, there is only one Janus cat, who made it through the first week, first month, and another 12 years. Let me introduce you to:
Frank and Louie
His (or her?) story started on September 8,1999. One day after being born to this world, he was brought to a veterinary clinic to be euthanized. That didn't happen thanks to Marty, who at a time worked there, fell in love with this cute kitten, saved him and has looked after him since. At the moment they live in Massachusetts.
Frank and Louie is the longest surviving Janus cat, and is 12 years old. From Behind, he looks just like an ordinary cat, fluffy, and ready to be cuddled. Only when you come closer you will see his three eyes (the middle one is not functional) and two mouths (only one is used for eating). He has one brain, so it really is a normal cat, just with a different look.
I personally think that Frank and Louie is adorable and very lucky to be well looked after!
