Siamese cat (definite introduction)
Such a gradient is related to genes. According to genetics mentioned in "Wikipedia", an enzyme that controls the production of pigments in Siamese cats contains a gradient. This gradient can guide this enzyme to process at high temperatures. It becomes unstable and loses its effectiveness. Therefore, the coat color is darker in areas where the cat's skin temperature is lower (such as hands, feet, tail, face, etc.), while the coat color is light in areas with higher body temperature.
In addition to Siamese cats, there are also some cats with heavy heart color blocks that have a similar situation. For example, Ragdoll cats (definitely introduced), Himalayan Persian cats and some Taiwanese Mix cats often appear to be completely white when they are young, but completely different when they grow up.
When the weather is cold and the temperature is low, the hair of Siamese cats accumulates pigment and has more dark parts. Therefore, the patterns of Siamese cats will be subtly different in high latitudes and low latitudes. The owner may also wish to check whether the color of its coat has turned lighter to guess whether it has a fever.
The most obvious example is that newly born babies are often whiter because the womb is very warm. As it grows, the coat color will change from completely white to light brown, and the coat color will begin to darken in the areas with lower body temperature on the nose, ears, tail, and pads of hands and feet. The entire face of some Siamese cats is dyed dark brown by pigment, while when the body temperature is higher, it is light brown or grayish white.
What’s interesting is that if a Siamese cat is unfortunately injured and the body temperature of the place where it is wrapped up becomes higher, when the bandage is just removed, the new hair that grows in that area will become lighter or even dull. Completely white, it will gradually return to its original color over time. Therefore, it is not an exaggeration to call Siamese cats the chameleons of the cat world!
