Siamese cats turn black in winter

       Many people don’t know that Siamese cats are known as “chameleons in the cat world”. Their fur color changes with age, body temperature and ambient temperature. The colder the cat is, the darker it is; the higher the temperature, the whiter it is.

       In fact, the mutation is related to the cause. According to the introduction of genetics in Wikipedia, there is a mutation in the enzyme responsible for pigment production in Siamese cats. This mutation can cause the enzyme to become unstable and lose its function at high temperature. Therefore, the fur color of cats at lower skin temperature (such as limbs, tail, face, etc.) is darker, while the fur color at higher body temperature is light color.

       As a result, many young Siamese born in the body of the mother cat usually have white fur. With the growth and temperature changes, dark color patches begin to appear. In the cold and low temperature environment, Siamese cat’s hair pigment precipitates, and the dark part is more. Therefore, in the high latitude and in the low latitude area, the Siamese cat’s color will also have the subtle difference. The owner can also observe whether the color of its fur turns pale, so as to speculate whether it has a fever.
