I have a van calico that is also odd-eyed. She is unusual in that her blue eye is on the side of her face that is tortie and her gold eye is on the side of her face that is white. Blue eyes are associated with the white-spotting factor and normally would be seen within the white area.

I also have six solid white cats: one blue eyed, two odd eyed (mirror images of each other), one green eyed, and two yellow/gold eyed. None of them are deaf. All of them are related. (They were rescues/strays from my neighborhood and all are spayed/neutered now.)

In most cases, you can distinguish at birth whether or not a white cat will be deaf. IF the cat has a black spot on top of its head(called a "cap"), then it will not be deaf. If there is no cap, then there is a possibility the cat will be deaf, though that isn't always the case.

My white cats all look very much alike and people are always asking me how I tell them apart. Most of the time, I can just tell by their body language. Sometimes they manage to fool me though and I have to look in their eyes.
