First, the reason why Siamese cats turn black
The body of many mammals There is a gene called TYR, which is mainly responsible for regulating the synthesis of tyrosinase, and tyrosinase exists in the cells of animals, which can promote the synthesis of melanin. Moreover, the higher the activity of tyrosinase in animals, the faster the synthesis of melanin in the body will be, and the amount will be more and more. The Siamese cat also has this gene expression in the body, and this genotype will also mutate with time and environmental changes. When the TYR in the body is mutated, it will cause its protein synthesis error, and then express different traits.
In addition, the mutation of the melanin genotype of Siamese cats also indicates that the tyrosinase synthesized in the body also has an unchangeable defect, which makes it unable to play a normal role at normal body temperature. A special point is: when the subcutaneous temperature of the animal is lower than 30 ℃, the activity of this genotype will increase, and the expression will be more active.
Two, will shaving a Siamese cat make it black?
Shaving a Siamese cat is not actually the main reason for the blackening of new hair growth, but that this behavior will speed up the blackening of its hair. Whether or not a Siamese cat’s coat
turns black is mainly determined by the temperature of its environment. When the temperature of the Siamese cat’s skin is lower than 30 ℃, the activity of tyrosinase in Siamese cat cells will gradually increase, and the change of tyrosinase activity directly affects the synthesis and distribution of melanin in the body. Therefore, when a Siamese cat is shaved, it will increase the synthesis of melanin in its body, which will cause its hair to darken.
Third, how to prevent Siamese cats from turning black
Because Siamese cats are blackened mainly by low temperature Therefore, if the pet owner does not want the Siamese cat to become darker and darker, he needs to take measures to keep his Siamese cat warm in time according to the changes in weather and temperature. The face of a Siamese cat, in particular, can turn all black as the temperature continues to drop.
However, the color of the Siamese cat’s coat will gradually return to white with the height of the temperature. Generally, when the Siamese cat lives in a warm environment, it will return to its common coat color.
Warm reminder: I hope pet owners understand the gene of Siamese cats before raising Siamese cats, so as not to see the hair of Siamese cats at that time Turn black and make an oolong, or despise it.
