Many people who have never raised a Siamese cat do not know that there is a secret in the body of Siamese cats, that is, Siamese cats are born white. They will turn black when they grow up. When the baby Siamese cats are born from the mother cat's belly, they are all covered in snow-white fur because the mother's belly is warm.
As As the dog gets older, the old white hair gradually falls off and is replaced by new hair. The face, ears and extremities generally become darker and darker.
The darkening and blackening of Siamese cat hair is caused by tyrosinase conversion The melanin is formed, and tyrosinase is sensitive to external temperature. When the temperature is low, tyrosinase can function normally and catalyze tyrosine to produce melanin, so you will find the blackened parts of Siamese cats Which ones have less hair and are exposed on the face, ears and limbs?
So many owners find that after neutering or shaving their Siamese cats in the summer, the belly of the Siamese cat grows out. It will turn black. This is a normal physiological phenomenon. The owner does not need to worry too much. The blackened coat color of Siamese cats will gradually return to its original color as the temperature rises.
