Can Maine Coons have blue eyes?

Image
'White cats and all cats with white may have blue or odd eyes'. That is a direct quote from the Cat Fanciers' Association (CFA) which fully answers the question.  To put it another way: All-white and particolor Maine Coons can have blue or odd-eye colours under the CFA and TICA breed standards. Other than cats with some white, eye colour "can be shades of green, gold, green-gold or copper. Those are the allowed Maine Coon cat eye colours under this association. The same applies to TICA. All-white blue-eyed Maine Coon. Credit: see image. There is not much more to say but I will say this. White fur is fur without pigmentation. The dominant white gene makes a cat all-white and the piebald or white spotting gene makes a cat partially white (bicolor or particolor)). Both these genes can affect eye colour in that they can make the eyes blue or one eye blue leaving the other I normally yellow (odd-eye color).

Heterochromia iridum means odd-eye colour in layperson's language. There are two cats in the picture as you can see. Both are totally white and both have odd-eye colour. They have the classic odd-eye colour which is one is blue and the other is gold-yellow. The cat in the background is not a Maine Coon in my view. If she is then she does not have the right type i.e. appearance to be a show cat because the muzzle is not strong enough and the ears are no lynx tipped. The cat in the foreground is very much a Maine Coon. Odd-eye colour is very common in all-white cats whether they are purebred or random bread. This is because the dominant white gene which removes pigmentation from the hair strands also removes pigmentation from one of the eyes leaving that eye blue. It is also claimed that inbreeding ("a lack of genetic diversity ") predisoposes animals to this condition. The blueness is caused by the refraction of light through the eye rather than by pigmentation in the ey...
