Many people do not know the specific genetic principle of the cat, and the specific probability of disease and other scientific basis. To put it bluntly, you are following suit. Take out what others say and paste it everywhere. Mix experience value, right? You like this, retell other people’s cloud, also don’t know a specific reason, make a rash conclusion, really very irresponsible. Those breeders want to control the breeding trend of cats and exaggerate things like this. But in fact, there is no big data statistics in the articles I have found. All of them are just a few cases, and they have made a conclusion. Can we be so irresponsible about diseases? People’s diseases, statistics, are tens of thousands, hundreds of thousands, and then thousands of poor, list the data, make experiments, statistical analysis of the test results, and then come to the conclusion that every sentence should be responsible, especially in terms of genes. However, I would like to ask the people in the field of pet medicine in China, how many experiments have you done to make a final conclusion, saying that “100% of the disease” occurs????? Therefore, even if it is not 100% of the disease, you people paste and copy what others have said. You leave the cat with no place to stand, which is too much for you. Anything should be based on research and data to say such absolute words! If you don’t know, please don’t pretend to understand, paste what others have said and answer everywhere. You don’t know whether you are right or not.
In addition, why does the hospital think that all the broken ear cats will get sick, because all the people who go to the hospital are sick, they have discomfort, their spirit is not good, and their posture is not correct, so they just go. It’s called finding patients among patients. Just like finding hepatitis B in hepatitis B patients (hepatitis B can cause liver cancer), is the incidence rate rising? Those who did not have the disease were rarely filmed by their owners for no reason. So, if you go to the oncology department, the probability of cancer is very high. Maybe 80% of cancer is cancer, so 80% of people will get cancer? Science can not be defined in this way. Incidence rate should be counted. All the folded ears should be counted. The hospital has 10 folded ears, 10 are sick, so the incidence rate is one hundred percent? The tens of millions of unfolded ears that remain on China’s vast territory incidence rate is 0? Or should the incidence rate be 10/ (10+ tens of millions)? In that sentence, leave room on your mouth and do more good to cats. Don’t use too much to cause a large number of folding eared cats to be abandoned on the street, which will lead them to breed with more stray cats, and lead to more common genes, which will lead to their lack of a foothold or even to be killed in the street! You paste it here and paste it in the past. Some people just join in the fun. In order to mix up the experience value of the answer question, my God, if you have a cat with folded ears and it doesn’t get sick, we all appreciate it, so that you can understand the situation. Maybe you don’t have a cat with folded ears. Why do you paste, copy and open your mouth all over the place? Just for the sake of experience, you resist the dealers with indignation. What you resist is the survival of these cats who have been made sick by human beings! The disabled are still brave to live, and cancer patients are also active after radiotherapy and chemotherapy. There are so many people with genetic diseases who are brave enough to live, and try to make their offspring’s genotypes not pathogenic. Even if they want to add children carefully to their families, even if they should not breed, why should they live or not? It is up to you to decide? Build up your virtue and do good!
The phenotype of the cat with broken ears is controlled by the gene of the broken ear. Chondrosis is controlled by the gene of osteochondrosis, which is two genes. The broken ear base is a dominant gene, so there must be at least one broken ear gene F, which can be FF or FF. However, chondrosis is caused by recessive gene A, and the carriers with a are normal or not serious. If AA is taken as an example, AA will not be particularly severe, but early The disease is usually AA. However, the dominant F gene of the ear fold gene can be bound to the recessive gene a of chondropathy, that is, the ear with F has a high probability of carrying a (but not the full band). Therefore, the parents who have ear fold carriers have ¡Á, (FA) (FA) A kind of (FA) (FA) has a quarter chance of giving birth to pure box FF and carrying the homozygous pathogenic AA gene (FA) (FA). It is not the ear fold gene that causes the disease, but the AA chondropathy gene. However, three quarters of the cat with broken ears are not homozygous, that is to say, 1 / 2 of them are (FA) (FA). Those with a are relatively normal, but can develop the disease. The onset age is late and relatively light, and some of them can even live to 10 + years old. A quarter of the cats are fully normal (FA) (FA), which do not show erect ears and have no chondropathy gene at all.
Then we discuss the carrier with folded ears (FA) (FA) and standing ears normal cats (FA) (FA). The most serious genotype is only (Fafa), accounting for 1 / 2, which is characterized by fold ear phenotype. The patients with a are relatively normal, but they can develop the disease, and the onset age is late and relatively light. Some of them can even live to 10 + years old. The rest were normal.
So why do some cat parents have ears, it’s still very serious?
We analyze that if the F gene and a gene are not completely locked together, then it means that FF can also have a gene. A gene no longer has any relationship with F gene and exists independently in the cat. That is to say, chondropathy is no longer locked in the broken ear cat, all cats can be the object of discussion. It’s just that these cats are less likely to carry a than those with folded ears. So a cat with erect ears (FF) can have AA gene or even AA gene. Well, all of them are possible. This is why standing ear and broken ear cat will leave a seriously sick broken ear. If a “a” is provided by standing ear and a “a” is provided by broken ear, homozygous AA will appear. The disease is very early and the disease is serious. But this pot should not be made entirely of broken ears.
In the same way, why can’t the vertical ears produced by Fafa with folded ears be used to see if they are sick or not. If the F and a genes are suddenly unlocked, then the kitten may be (FA) (FA). So it’s not safe. If two such cats can produce Fafa with rickets, the probability is relatively small, and it is not completely free from rickets. Even the parents of the cat can have rickets!
In addition, we also consider why cartilage AA disease occurs in FF, which may be due to chromosome formation, gametophyte formation or oocyte formation. In other words, F and a are originally in the same gamete or assumed to be on the same chromatid, but f is no longer the same as a due to the chromosome’s * or translocation If f is consistent with a, then the cat with broken ears will no longer have the disease, and has no disease-free inventory for more than 10 years. In addition, if f is consistent with a, FF ear cat will show AA pathogenic gene instead. Then this gene has been included in the gene of the standing ear cat by the calculation of the reproduction of the cat, that is, Fafa. If the offspring are reproduced in the early years, they are normal with Fafa, while the carrier is Fafa. If two carriers have the same chance to give birth to (FF) AA in a quarter of the time, the conclusion is that a very small number of the standing ear cats that you see running all over the street also carry the gene of rickets. If they meet each other, the two carriers will probably give birth to rickets cats!!!!! In particular, inbreeding in cat houses will increase this opportunity.
Therefore, the theory of “ear fold” is not a hypothesis of “ear fold” in cats. From the reality, it is verified that there are some folding eared cats who live to be teenagers and do not get sick. 2. The cat with folded ears has been bred and should be treated and cared by human beings. 3. Even if the parents are not broken eared cats, they may not get “rickets”, but the chance is relatively small. 4. If the backyard cat peddlers have inbreeding, “whether it’s broken ears or erect ears,” the probability of rickets will increase, not only rickets, but also other diseases. 5. There is a large number of inbreeding in pet shops, which makes more and more sick cats. It is not safe for cats in pet shops. 6. Please don’t know anything about genetic knowledge, Xiaobai. Don’t paste and copy other people’s words, such as “how can a cat with folded ears get sick again?” please tell me how much medical theoretical knowledge you have, how much scientific research you have done, and how much data you have collected. Some articles, a total of 7 cases, dare to say that a hundred percent of the disease, I would like to ask you this sentence is copied from the predecessors, then your predecessors’ data is how big? Seven cats, too? Five cats? In China, there are few articles about folding eared cats, and there are few experiments. Therefore, you can follow what others say, and then the public will say what they say. Such an attitude is too irresponsible to a cat’s cat. It’s possible that it’s the one that’s been abandoned on the street. It is possible that it is the cat that the owner has been raising for more than ten years. How much knowledge of the truth, how many experimental data, so that you can say that definitely, will be sick, more learning, more proof, do not open your mouth is certain. If you want to persuade the cat dealers in the backyard not to fold their ears and match their ears, you can reason, speak science, and tell them why it is not possible, instead of slandering the poor strains created by human beings. Respect your mouth, do good deeds, and the cat is also a life! Should not be abandoned and abandoned at birth.
The reason why the ears of folding eared cats are folded is that their genes have congenital defects. This congenital disease is called chondroossification dysplasia. The onset time of this disease is usually between two months and six months old, and some diseases begin to show symptoms after one year old.
The initial symptoms of cats are that they don’t like activities at first, and then they move slowly.
A lot of people think that folding eared cats are very cute when they are sitting like people. In fact, this is because their hind limbs are stiff or they feel pain when flexing.
There are also some lazy, soft and cute postures, which are caused by abnormal bones and joints of hind limbs, bending deformity of foot bones, thick, short and stiff tail, unable to swing freely. These symptoms can’t be cured, and even the disease may continue to worsen. Because the disease is caused by genetic defects in the ear itself, it can’t be treated at present Almost all the broken ear cats have to face the disease.
The onset of the disease is very painful for the cat, so if your cat is sick, you must pay more attention to take care of it, give it more care, and reduce its pain.
Can’t fold ear really raise?

They’re trying to stop the backyard cat dealers from breeding. If a cat with a broken ear or a non close relative has a healthy ear, the offspring will not be pure ears broken, and the age of onset will be delayed. Even if the disease occurs at the age of 10, who will have no pain when he is old, and he will still have cancer when he is old. Compared with cancer, skeletal disease is nothing. However, the backyard cat dealers are generally inbreeding, and then it is easy to produce pure fold eared cats. They are easy to get sick, and it is not easy for cats to be born. Therefore, they smashed all the folding eared cats in one stroke, trying to control the cat dealers in the backyard through excessive and complete boycott! In fact, this is not right. There are so many genetic diseases in human beings, and there are hundreds of millions to tens of millions of bad gene carriers. According to the global 6 billion, there are hundreds of millions of thalassemia gene carriers alone. Not to mention the total number of gene and chromosome diseases, these people will not live? It’s just that we can learn that one parent is not a close relative. Well, this cat can be raised. If you go to a pet store to buy a cat, you may buy a week and the cat will die in one week. At least some of the broken ears can live for 10 years and 8 years. Therefore, the folded ears bred by family planning can be raised. These people, in fact, do too much, they have no right to let a species perish, since it was born, it should be cherished. Old people, but also what arthritis, rheumatism, gastroenteritis, low back pain, lumbar disc protrusion, it is not that there is no old man. Listening to the wind is rain. How many people have done scientific research, raised cats for more than ten years, and then published the experimental data into papers? No, it’s basically based on opening your mouth. Even if there is a problem with this gene, we should treat it on a case by case basis, and we should not arbitrarily deprive carriers of their right to live. If anyone dares to say that there is something wrong with a certain gene in a person, and then this kind of person should disappear, I am afraid he will first examine his education background to see whether his paper is true, how many experiments have been done, whether the experiment can be repeated, and whether the conclusion is consistent. If he is found to be talking nonsense, he will be sent to prison, which belongs to academic fraud. The reason why these people don’t keep the door open is that the target is the cat, and no one gives the cat. Otherwise, it will be enough for them to go to prison for a while.
I’m 10 years old. I’m very lucky. I’m not sick. I’m 12 Jin. I’m fat. I’m short. I’m active. I don’t have any bone problems. I’m also very strong. I’m super bouncing.

In addition, I have three folding ear cats, the older 10 years old, no disease, lucky.
As long as there is a broken ear gene, it’s impossible to have 100% normal bones, just a serious and slight difference.
The hereditary skeletal genetic disease of the cat with broken ears is called “abnormal development of cartilage and ossification”. The age of onset generally ranges from two months to six months. Recent cases have shown that adult cats with broken ears also have a chance to develop the disease.
At the initial stage of the disease, the cat will show no activity, and then the movement will be obstructed. Obvious symptoms include limping of the hind limbs, frequent lifting of the hands, arched back, walking like walking on stilts, etc.
But folded ears and drooping ears are a genetic defect. They often stand not because they like it or because they become fine, but to relieve the pain when the disease occurs.
In 1971, GCCF, the largest cat club in the UK, banned the use of cats with broken ears because of a genetic disease with severe bone lesions found in them.
The obvious symptoms of bone genetic diseases are as follows
1. The tail is thick and short, stiff and inflexible, and the tail of some sick cats can’t swing;
2. The hind limbs are too short with unusual curvature, augmentation or mass;
3. The joints of limbs were swollen;
4. The hind paw is extremely thick. If you observe carefully, when the cat sits upright, the pillow meat of the hind paw cannot touch the ground;
5. Nail growth is abnormal.
In some cats with severe illness, bone lesions will slowly spread to the spine, paralyzing the cat and causing great pain. When the cat can’t bear the pain, the owner has to put the cat to death.
Not necessarily, if the cat carrying a Fd gene is relatively high incidence rate, it can be judged by the tail that the tail is hard and short, which is a sign of the disease.
According to foreign records and gene analysis, the reason why the ear fold forward of Scotch cat is that it is controlled by a mutation gene named FD on the autosomal, which is dominant inheritance. In general, when breeding, the Scotch fold eared cat will breed with American short hair cat or British short hair cat, so as to give birth to relatively healthy folded eared cat.
However, it is not to say that the cats bred in this way will not have the risk of abnormal bone and cartilage development. As long as the cat carries the FD gene, it is likely that the disease will occur. It is just that compared with the offspring of the Scottish Fold eared cat and the Scottish folded ear cat, the incidence of the disease is younger.
People without rich experience can’t distinguish between the false and the true fold caused by the weather or physical changes, especially those with extremely poor quality, which have very large ears, sometimes even the professional breeders can’t tell.
There is also a real case of broken ears and English short breeding that will still lead to sick cats, that is, the ears themselves are disqualified and not suitable for breeding, such as hard tail, such as short tail, these symptoms are symptoms of disease. Therefore, this breed is very special and requires the breeder to have professional knowledge and certain experience. Therefore, random breeding is not recommended.
A cat with broken ears does not necessarily get sick. The probability of the disease is about a quarter. The judgment is based on the fact that if you can’t jump for three months, it’s basically that if you break your ears and fold your ears, the unfortunate quarter of them will have diseases.
Scottish fold is a relatively young breed in the pedigree of purebred cats. In the process of breeding, it inherits the advantages of strong body, lively and lovely, and strong disease resistance of the above two kinds of cats, so it becomes a kind of purebred cat which is easy to raise.
As long as all cats with broken ears carry the FD gene, they will have osteochondral dysplasia (OCD), but to different degrees. If it is not serious, even without clinical symptoms, it needs x-ray / X-ray / radiology to find out; if it is serious, there will be a variety of symptoms such as tail thickening and shortening, joint deformity, pain and so on.
Generally speaking, heterozygous offspring (one parent with a broken ear and the other with normal ears) developed symptoms later and had a relatively low severity; homozygous offspring (both parents had broken ears) had earlier and more severe symptoms, which usually occurred in 2-6 months.
The following symptoms may occur in the affected cats:
1. The tail becomes thicker and shorter and does not bend.
2. All limbs may be lame, like walking on stilts.
3. The claws are shorter and the palms are swollen.
4. The ability to bounce is reduced.
5. The so-called “Buddha position” is the sitting posture in which the buttocks and waist are stressed and the two hind legs are stretched backward.
If you have a cat with folded ears, don’t abandon it because the genetic disease can’t be cured. At present, the cat can be screened for ear fold by gene detection technology of Hino valley. If the genetic gene is detected, the owner can delay the onset of the disease as soon as possible through diet intervention, drug treatment and regular physical examination, so as to make it live more comfortable ¡£
The so-called “disease”, which is also a point of the cat dealers, does not mean that there is no disease. We all know that the cat with broken ears has genetic disease, that is, abnormal cartilage ossification. What is the direct manifestation of this disease is “broken ears”.
In other words, as long as it is a cat with broken ears, it means that it has inherited the disease. The difference lies in the severity of the disease. Therefore, there is no question of whether the cat will develop or not, but the severity of the disease. Even if a cat with broken ears does not have the so-called “onset”, it is accompanied by various degrees of joint inflammation. Why is this kind of cat relatively quiet?
If a person has this kind of disease, it would be a ghost not to be honest and lazy. Think about the cat’s natural activity… Ah, I don’t want to say that. If a cat with a broken ear gene is hybridized with a normal cat, the genetic defect can be greatly improved, thus reducing the degree of dysplasia and slowing down time.
In fact, the cat with folded ears is a short gene mutation, and it is not even a new cat species at all. Therefore, the Cat Association in Europe does not recognize this cat species. A cat with broken ears should be called a “broken ear disease” cat.
A cat with broken ears does not necessarily get sick. It can be judged by the phenomenon of limping in the hind limbs, often lifting the front foot, bowing the back, walking like walking on stilts, the cat’s tail appears thick and short, the joints are stiff and unable to swing, the bones and joints of the hind limbs are abnormal, and the foot bones are deformed and bent, which are much shorter than those of normal cats.
The latest clinical data show that 7-week-old kittens may have the symptoms of skeletal disease, which is generally manifested as the deformation of the bones at the ends of the limbs, and the hind limbs are more serious than the forelimbs. However, because the cat is in the early stage of the disease, the pain is less, so it will not show obvious symptoms. If you want to make an early diagnosis, you need the help of X-ray, so it is easy for the owner to ignore it. Many veterinarians said that most of the cats who came to see the doctor were seriously ill.
Like other cats, the daily necessities of a cat with folded ears include: a litter basin, litter, a bowl for eating and drinking water, a cat climbing frame and a cat scratch board. In addition, a warm and comfortable cat’s nest should be prepared for the cat. The cat’s nest should be placed in a sunny and ventilated place. This kind of cat can also bask in the sun while sleeping. Sunbathing is very important for cats, which can supplement calcium It can also kill bacteria.
A certain amount of drinking water should be ensured for the cat every day. Therefore, proper amount of fresh drinking water should be prepared for the cat every day. Instead of drinking tap water, the cat must drink cold boiled water. The drinking bowl should be cleaned every day, and the bowl should be wiped dry before being put into the drinking book.
The cat with broken ears may not always get sick. Once it is found that it does not love to move, and its movement is impaired, it is the performance of the initial symptoms.
The symptoms of the disease were as follows
It is characterized by a stiff tail, severely deformed feet, unable to support the weight of the body, and ingrown nails that may penetrate the soles of the feet. This kind of deformity begins to show gradually from the cat’s 2 months old, the pain of the immature cat is very obvious. The onset period ranged from 2 months to 6 months. Some cases began to develop after 1 year old.
Many cats with broken ears will show symptoms of genetic diseases soon after birth. Some studies have shown that the onset time of kittens whose parents are both with folded ears will be earlier, while those with only one parent with broken ear gene will have a later onset. If the newly born cat is not active and sleepy, always stays in the same place and does not like jumping, it is likely that the cat has already developed the disease.
This hereditary skeletal disease can not be prevented or cured. It can only be found when cats get sick, and most of the disease will continue to deteriorate. Cats need to spend their lives in pain and medication. In some cats with severe illness, bone lesions will slowly spread to the spine, making the cat paralyzed is very painful.
Random mating is strongly opposed by cat lovers!!! First of all, your cat’s parents don’t know whether it’s absolutely purebred. What’s more, the born kittens are more likely to get sick. We hope to sterilize this cat and not mix it with purebred cats. Only those with breeding grade approved by CFA or TICA Cat Association, and not suitable for ordinary people, must have knowledge. In order to protect purebred cats, please do not do so! Since the kitten is born, we should raise it well. Remember, it must be sterilized!
Fold ear with stand ear match out, the probability is not very big! Look at the kitten, there is no ear fold feature! If you are worried, feed some cartilage powder!
It is said that in 1962, the female cat in Scotland gave birth to a litter of kittens. One of the cats had its ears folded down and never stood up. This is the first cat with folded ears in history. Later, the cat gave birth to another small folded ear, which attracted people’s attention. The shepherd’s neighbors of the hunter began to breed new products with crooked ears, and finally succeeded. But what I didn’t expect was that this kind of cat with folded ears was born with genetic defects. If it was a kitten bred by two fold ears, it would have a serious genetic disease. If it broke out, it would cause lifelong pain. Otherwise, it would have many problems. The cat with broken ears is born with inherited skeletal disease, which is called “cartilage ossification dysplasia”. The reason why the cat’s ears play like this is due to a dominant gene mutation. At that time, it was believed that as long as the folded ear cat and the standing ear cat were bred, the wheat would be free from genetic diseases. However, this was not the case. If the ear was broken, it would carry genetic diseases. If it was a vertical ear, it would carry an invisible gene. It may or may not develop disease. Compared with the broken ear, the risk of disease is only a little lower. Although it is said that not every cat with broken ears will get sick, even if it is not, compared with other healthy cats, it will also have problems such as weak physique, joints and foot deformation. If you find that the sitting posture of a cat with folded ears is the same as that of a human, you should never feel cute, because it is caused by stiff hind limbs or pain. Once such a situation occurs, we must be vigilant. Because it is a natural genetic disease, it can not be prevented and can not be cured. As long as the disease occurs, the poor cat with broken ears will spend his whole life in pain and medicine, and if the disease is serious, it will eventually lead to paralysis!
More pure within half a year, not very pure more than half a year, or even more than ten years before the onset can be. Some folding ear cats will never get sick. For example, my family’s folding eared cat is a teenager and has never been ill. It has a strong spring power and is short and beautiful.
Instead of boycotting backyard cat dealers to breed jacketed cats. It’s better to say that the cat with broken ears is synonymous with genetic diseases. No matter whether the ears are broken or the ears are erect, as long as the backyard cat dealers still have inbreeding pet cats, there will be more and more genetic diseases, not only chondropathy, but also heart malformations, and so on. With this trend, pet cats will become more and more unable to keep alive. Even if it is not a cat with broken ears, they can suddenly die of genetic diseases. The conclusion is that the backyard cat dealers only seek profits, resulting in inbreeding of cats, resulting in more and more pet cat diseases. Generally, those people are silver layer with silver layer, blue cat with blue cat, each introduces a litter of cat, if brother and
