Siamese cat's limbs and face are black, and its black color will change with the temperature. The color of Luo Cat's face was a faint black spread from the center of the face. But when the weather is cold in winter, the whole face is pitch-black, a black patch. The Ragdoll sometimes finds that there will be such changes, is it the same as Siamese?

          Ragdolls and Siamese cats In addition to looking a bit similar, there is also a special physiological characteristic, that is, all puppets must first be a point color cat with the Siamese point color gene. The color rendering principle of the dark color of the puppet is the same as that of Siamese. It is the same, there is a tyrosinase in the body of the puppet cats that is involved in the synthesis and deposition of pigments, which will become unstable or even unable to function under high temperature conditions.

          In low places (such as limbs, tail, face, etc.), tyrosinase is active, and the coat color is dark, while in places with high body temperature (such as the back), the activity of tyrosinase is limited, and the coat color is light. This leads to the reason why we shave the puppets when the weather is cold, and the newly grown fur will become darker and darker, and the fur will not change back to the original color as the temperature rises. Secondly, according to the descriptions of the two-colored puppet cat associations, it can be considered that the color of the face and ears of the two-color puppet will be visible to the naked eye and darker than the color of the body part. Usually there will be a visible change.

          Ragdoll cats will not become black puppets after one shave. The color of the puppet cats' hair is fixed before birth, and no matter how shaving, there is no way to change it.
