The blue eyes of the kitten, a promise not maintained?

Maya when she was a kitten, her eyes are blue

When he opens his eyes, irrespective of the color of his irises in adulthood, the kitten has blue eyes. A color that most adult cats do not keep, except colorpoint and white cats or with a lot of white. In the first weeks, only the deep layer of the iris is seen, which is usually a gray-blue.

The beautiful green eyes of Maya adult

Over the days, the genes responsible for the coloring of the eyes are expressed, determining the appearance in the eye of a brown pigment, melanin, in kittens which once adults will have green or orange eyes. On the contrary, in those who will keep their blue eyes, their genes will have blocked the production of this pigment in the iris. Around 6 weeks, we know if the animal will keep blue eyes or if brown pigmentation has begun.

What is interesting to note here is that the same pigment cells that are responsible for the color of the skin and fur of our cats, are also responsible for the color of the eyes. Without these cells, one eye is blue or the hair is white. Well the disposition of these cells depends on their migration to reach their final location in the embryo. If the pigment cells did not go far enough to give color to the hair then probably they did not do it for the eyes either. That's why the more white we have, the more likely we are to have blue eyes, especially in a completely white cat.

Does that mean that a black cat with blue eyes is an unattainable fantasy? Well, that's the whole question.

Merlin, our black cat with blue eyes, with very little white

Merlin the Enchanter: between curiosity and dream

A black cat with blue eyes, with very little white, has an enchanting side that leaves no one indifferent. The contrast of blue eyes with a dark black coat (or red or blue or another one) evoked in me a so great curiosity that I could not resist and then Merlin joined us.

Those are not Siberians, but cats with a rare and new mutation that is the topic of study of researchers and enthusiasts around all the world. These cats therefore have no pedigree, the goal being for now to ensure that the gene is not associated with major health problems. Only then I will decide whether to invest myself in official recognition and in what terms.

What is sure, I will not embark on a project of blue eyes Siberian cats. I'll not introduce the blue eyes in the Siberian breed, since the main charm of this breed is its relatively natural and rustic trait, and especially its "little worked" feature.
