In the eyes of dog owners, the cat is already quite mysterious. If it is a cat that can constantly change its coat color, is it like a chameleon? More magical?
recently set off a hot topic on social media in Japan. It all started with a poop scavenger named "Qiujun" posting photos of his Siamese cat on the Internet.
The Siamese cat in the photo is quite cute. Although the face is black and black, it’s like being burnt in a cartoon, but this is what makes the Siamese cat special. .
And what's interesting is that it's like getting into the coals and playing in the dark. It makes people laugh at it! This sharing naturally attracted some cat-loving officials to like it!
Just as many netizens envied Qiu Jun’s family for raising so many Siamese cats, and he could replace one cat with another one every day, Qiu Jun said that they are all the same Siamese cat. "Kawasaki".
What makes me even more puzzled is that Kawasaki has changed from a white cat to a black cat, and a little black hair. Become a gray, gradually tending to white. And these photos were taken within a year, that is, during this time, Kawasaki changed color like a chameleon.
Many netizens feel quite amazing. Is Kawasaki a different cat with different bloodlines? Under such doubts, the news that the Siamese cat could change color in Kawasaki was quickly forwarded frantically by netizens, which attracted a large group of shit shovel officers.
Many netizens also made a clear comparison of the changes in the coat color of Siamese cats in their homes. For a time, an interesting topic of "Siamese Cat Discoloration Championship" was triggered.
When I was a child, it was only white, just as beautiful as a layer of snow. Why does it turn black when I grow up, and even change the color of the coat in a certain period of time?
Some shoveling officers who were completely confused and even shouted: "Did my cat be secretly exchanged?" Some netizens even think that these Siamese cats have skin diseases. Causes a change in hair color.
Of course, these Siamese cats are not caused by skin diseases that cause hair color changes, but Siamese cats themselves are somewhat different from other cats, which led to this kind of cat "Discoloration" on the body.
It is well known that the color of a cat’s coat is determined by genes, and various patterns such as the formation of some fur are caused by modified genes. There is a special modification gene called Siamese allele in Siamese cats, which can cause mutations in color genes.
"Point coloration", the key color is the most easily recognized feature of Siamese cats, that is, most of the body is white or cream, and the ears, face, hands, feet and tail are Darker black or chocolate color.
The interesting fact that Siamese cats are different from other cats is that their coat color is not static, but changes with temperature.
In fact, as early as the 1930s, scientists have discovered that Siamese cats have this characteristic, and even did a study to solve this question.
The scientists brought the Siamese cat to Moscow and took care of the Siamese cat in a room between minus 3 degrees Celsius and 16 degrees Celsius. When these cats arrived in Russia, their bodies were cream-colored, but they eventually shed their old fur and became noticeably black in colder temperatures. This is the first verification that the coloration of Siamese cats is affected by temperature.
To confirmDetermined that this color change is really due to temperature changes, scientists hypothesized that if they keep the dark fur on the cat warm, it will become lighter.
To prove this, they shaved part of the cat's hair and covered it with a bandage to keep that part of the cat's skin warm. Sure enough, when the hair grows back, the hair in the specially treated part will be lighter than the surrounding hair exposed to a lower temperature.
This research topic is "TEMPRATURE EFFECTS ON THE COLOR OF THE SIAMESE CAT" (the effect of temperature on the color of Siamese cats), and its results were even published in the then "Genetic Journal", through a series of data to prove Siamese There is a correlation between Luo cat's coat color and temperature.
Generally speaking, the change in coat color is considered to be caused by the tyrosinase involved in melanin production in the body. However, due to special genes in Siamese cats, the mutant tyrosinase is not Heat resistance, that is, in a high temperature environment (generally 36.7 degrees Celsius as the boundary) tyrosinase does not work, the melanin decreases, resulting in the hair color tends to white.
The parts with lower body temperature, namely ears, face, hands and feet, and tail are caused by activated tyrosinase to produce melanin, so these parts tend to be dark. Popular understanding is that the higher the temperature of the body part, the lighter the coat color, and vice versa. Therefore, it is not unreasonable that Siamese cats are often jokingly called "coal miners".
Then, if a friend who is paying attention will find one special, that is, Siamese cats are pure white when they are born.
That is because in the warm body of the female cat, the temperature is higher than the conditions required to activate tyrosinase, so the hair color of the newly born Siamese cat is pure white, one week after birth Around, and over time, the color of the hair will gradually change.
Therefore, although Siamese cats are only divided into 4 varieties under the coat color recognized by CFA in the United States, seal key color, blue key color, chocolate key color and lavender key color .
However, there are as many as 30 other coat colors recognized by GCCF, so in addition to the iconic key color of Siamese cats, some Siamese cats may grow up to become similar to other breeds.
If there is no relevant professional knowledge, as the cat's hair color changes, it is difficult to tell from the appearance that this is a Siamese cat breed. (Hey! I always feel this contrast, not only the color of the hair, but even the amount of meat has changed!)
until the end, I really feel that the shoveling officer can't help but make a spit: "What about you? Who is it?" The feeling is quite interesting.
But because of this, many netizens said that this is the fun of keeping Siamese cats? Because the shit shovel officer can be honest and "self-deception" to change the target! It's a perfect example of different enjoyment for the same cat!
Of course, this is just a ridiculous joke. If you have cats in your house, don’t just throw them away, because cats are just a passer-by in life for the shoveling officer, but For cats, the shoveling officer is their life!
