personally i think the one the original poster posted is just freaky
I came across a site that says
A photo of a one-eyed kitten named Cy drew more than a little skepticism when it turned up on various Web sites, but medical authorities have a

“Holoprosencephaly” causes facial deformities, according to the National Institute for Neurological Disorders and Stroke, part of the National
Institutes of Health. In the worst cases, a single eye is located where the nose should be, according to the institute's Web site.
