super cute cross-eyed cat Spangles
Siamese cats are prone to cross-eyed, which is actually related to genes. The characteristic of Siamese cats is that they only have black hair on their faces, ears and extremities, and the rest are light cream; This is due to their unique Siamese genetic genes. Siamese gene can inhibit the production of melanin, but the lower the temperature, the less the effect of Siamese gene, so Siamese cats will be black in the face, ears and limbs with low body temperature, which is generally called the key color.
In animals lacking melanin, the optical nerves sometimes intersect in the optic chiasma, resulting in abnormality. Because the conduction path of the optic nerve has been determined during the development of retinal cells, it is generally believed that the abnormality of the conduction path is related to melanin.
In fact, not only Siamese cats, cats with light color genes or cats with Siamese key color genes are more prone to cross-eye than ordinary cats. In addition to cross-eyed, they are also prone to eye tremor.
A cat with cross-eyed eyes will have a narrow field of vision and see things less stereoscopically. But if it is generally raised indoors, it will not affect daily life at all! Therefore, everyone does not need to specifically exclude raising cross-eyed cats! It is worth noting that cross-eyed may also be caused by neurological diseases. If an adult cat suddenly appears cross-eyed symptoms, don't be careless. Take it to see a doctor immediately!
