Why do people like cross-eyed animals more?

More than a few times I have seen cross-eyed animals in the news.
There were cross-eyed ferrets, dogs, cats, rats in the news many times in just 2012.

When an animal is cross-eyed, everyone seems to think they are cuter, and they become stars. When a human is cross-eyed, they don't get the same kind of attention, and certain nobody thinks they are cuter. O_o Why?

Now here is another cross-eyed animal, a cross-eyed cat to be more specific. Check out his photo below,

Another cross-eyed star from Germany,

Do you think cross-eyed pets are cuter or more special than regular pets?
If so, do you think cross-eyed humans are cuter too?

P.S. Post some cross-eyed animal photos if you have any.
