Someone told me that for kittens to have blue eyes BOTH parents must have blue eyes as well. This doesn't sound right to me, but I don't know. Any experts out there know the facts?
Not true. Siamese cats have blue eyes (as do all colourpoint cats), and two Orientals which have green eyes can produce a Siamese kitten with blue eyes. They both have to be carrying colourpoint.
What can't happen is a Siamese cat (or any pair of colourpoint cats) producing a cat without blue eyes.
There are also other mechanisms that give cats blue eyes associated with being white all over, I don't know what the genetics there are.
Thank you, I was asking cuz my blue eyed Tortie point with blue eyes has had 4 other litters. The owner said all her kittens had blue eyes. From what I saw this was true. She kept them all. Even orange an white tabbys, all black, tons of different color patterns all with blue eyes. I didn't think the dads all could have blue eyes!? I'm so hoping this litter will be blue eyed as well. Easier to find homes for them.
So it must have be a dominant, directly from mom. An individual mutation here, or is there some other, more common, feasible way to achieve dominant blue eyes? That is what we do have to ponder about here.
