Both folded ears and folded ears are born with genetic diseases. If you want to breed healthy folded ears, you need to fold ears and short American short English short match. Bad cat dealers will let the folded ears and folded ears match in order to increase the birth rate of folded ears. It can only be said that a healthy folded ear is also a genetic disease gene, and it will not occur itself, but if it is healthy with another folded ear, the child will also have a disease.
Therefore, folded ear cats are not allowed to parents are folded ears
Scottish folded ears
In 1897, Professor CORNEVIN pointed out in his animal breeding rules that a long, obese short-haired overhanging ear breed lived in its hometown, China. The dominant gene trait that causes cat ears to flip forward was first discovered in Scotland in 1961. WILLIAM ROSS, a shepherd at TAYSIDE, and his wife, Mary, found a white female cat named SUSIE rolled up ears on the MCRAE family's farm next door. SUSIE gave birth to SNOOKS, a white female cat with equally rolled ears. After mating with an English shorthair. SUSIE gave birth to a white tomcat SNOWBALL. The new breed was then named the folded-eared cat based on the heritary characteristics of its rolling ears. Unfortunately, the knowledge of the breeders at the time, and the breeding methods to increase the incidence of folded ears, made the limbs, tail and joint deformities and the dominant genes of the folded ears so that in 1973 the GCCF had to terminate the recognition of the breed.
In 1971, Mary Ross sent some Scottish folded-eared cats to an American geneticist, Neil Todd. The geneticist began breeding the variety again. After crossbreeding with The English Shorthair, the Exotic Shorthair and the American Shorthair, severe joint deformities were brought under control. And gradually established the current breeding rules for folded-eared cats. Also because of this new rule and the efforts of many years of breeders, this breed is getting healthier and healthier, gradually getting rid of those disease-causing genes. But breeding and introducing a gene is easy, and it is quite difficult to eliminate, so it will take a long time to try to eliminate it.
CFA and TICA recognize this extremely successful breed in the United States. In 1980 the variety began to re-enter Europe. France's first Scottish folded-eared cat was born in 1982. But neither FIFe nor GCCF recognizes the breed. Throughout the Continent, Scottish folded-eared cats are rare.
In the United States, the Scottish folded-eared cat crossed with the Persian cat, which increased the probability of the appearance of the long-haired gene carried by the original barn cat itself, resulting in a new type of long-haired individual, called the Highland Folded Ear or Long-haired Scottish Folded Ear Cat. CFA, TICA has recognized the breed, and the current CFA has abolished the use of Persian hybridization of the long hair folded ear, and the long hair fold ear must also follow the breeding mode of the short hair fold ear. to make this variety healthy again.
In 1987 in Germany, the crossbreeding of scottish fold-eared and Lex cats produced pudelka tze or shepherd cats, a cat with curly fur and ears hunched. Because the number of PUDELKATZE is still very small, it has not yet been recognized as a breed.

Unqualified features: the tail is too short, due to the unusually thick tail vertebrae and lack of flexibility, the toes are deformed.
features:
Scottish folded ear cats have a particularly peaceful personality and are very good to other cats and dogs. Gentle, affectionate, loving, playful, and cherish family life. Their voices are soft. Tenacious in life, the cats of this breed are excellent hunters. The coat care is very simple, and you can comb it once a week. During hair removal his long, fuzzy coat needs to be groomed frequently. And special attention must be paid to its ears, in order to prevent deformation of the ear bones, two folded ear cats can not mate and breed, it can be mated with the li ear cat (Scottish fold ear li ear cat), or the English shorthair cat and the American shorthair cat. If crossed with an English shorthair or an American shorthair, its offspring, regardless of whether the ears are folded or not, are counted into the Scottish folded ear breed, and the part with the erect ears cannot be counted back to the English shorthair or the American shorthair. This hybrid breeding is an irreversible form of reproduction, and the traits of the folded-eared cat do not appear until the third to fourth week. And the degree of ear folding is not determined until the fifth to sixth week.
Roughly speaking of the historical characteristics of this breed, in fact, it is not difficult for everyone to see that this breed is not as currently rumored, the current misunderstanding of many people is to confuse the concept of breed cats, purebred cats, cats, cats, in fact, we are now called purebred cats, which are fundamentally correct to say that there is no purebred cat, purebred cat, the term purebred cat has always been the misunderstanding of ordinary people, especially the so-called breed cats we are now breeding are basically the result of artificial directional breeding, Unlike wild cats, they are not animals that live in nature, with their own characteristics, breeding standards and requirements, and ways of controlling the number of breeds. So there is no current first misunderstanding of the sterilization of pet cats, breed cats are inhumane, because they are not wild animals, their survival does not have a natural balance of this natural law to control, and because they are artificially targeted breeding, so their survival of the fittest has become what every breeder must do, as a hobbyist, you love a breed to respect their breeding standards and rules, you have to be a qualified scientific owner, resolutely do not breed them easily, resolutely do not breed pet-grade cats, Resolutely achieve breed cat pet sterilization and breeding. This is the so-called humanity, not disorderly breeding, not random breeding in order to allow more resources to protect wild cats, but also to make your favorite breed develop benignly so that the species is excellent to continue. In the future, don't argue with each other about whether pets need to be sterilized, which is just a waste of time and energy.
Some people also say that although the folded ear is the consequence of genetic mutation, not artificially created, but his mutation is problematic at the beginning, why can't humans resist and destroy it, in fact, there is such a statement or the same out of the concept I mentioned earlier, the folded ear cat It is a new species produced by the mutant gene, and then after artificially targeted breeding fixed breeding, her gene If the mutation at the beginning is a problem, then he himself will already be eliminated by nature. But from the historical point of view, the original folded ear cats they are healthy, their unhealthy is because of artificial interference in their reproduction, too many folded ears and folded ear breeding methods and excessive inbreeding, so that they have the current situation, we assume that they are mutated but not discovered by humans, and the number of natural mutations of the folded ears is very small, their natural way to continue offspring can only be to find those cats without mutations for mating, under that kind of breeding, The ear fold gene is dominantly inherited, so there will still be individual ear fold cats, but their normal breeding will not produce a large number of close relatives and the overbreeding of two folded ears, so their offspring will live normally and healthily in the barn where they first appeared. But the current situation faced by the folded ear breeder is an originally healthy breed, has become no longer healthy for historical reasons, the original American breeders also found this problem, so try to use mature hybrid breeds and natural breeds to improve this injured gene pool, the British shorthair cat is a mature hybrid breed, the American shorthair cat is a mature natural cat breed, they all have the excellent genes needed for the folded ear, so in the end these two breeds were identified as hybrid cat breeds used to help this breed to health and recovery. And through the joint efforts of many folded ear breeders, this breed has become more and more healthy, can live to 25 years old folded ear is no longer unusual, some of their excellent variety characteristics have returned, they are gradually getting rid of the nightmare left by history to them, this folded wing angel began to grow their wings, and now the folded ear breeders are engaged in how to make this breed in the good performance of the characteristics of the variety at the same time to better restore its original health. In fact, everyone knows that it is easy to bring a gene into the breed, but it is quite difficult to get rid of a gene from it, so in this regard enthusiasts need to give the current breeders time, affirmation and support, rather than cracking down on slander, especially in China
