HAIRLESS CATS
Copyright 2002 - 2013, Sarah Hartwell

The origins of the major hairless breeds are well documented elsewhere so I have included a summary only. In some instances there appear to be several versions of events, dates of origin or disagreement over some issues. Where this is the case, I have included all relevant information without prejudice. Other opinions are mine alone. 

HAIRLESS CATS

Hairlessness is a trait which has occurred in several places at different times. Hairless cats have been reported from Latin America in 1830. There are reports of this mutation occurring in France, Austria, the Czech Republic, England, Australia, Canada, USA, Mexico, Morocco, Russia and Hawaii. In addition, Devon Rexes are prone to baldness due to fragility of the hair and some LaPerm cats are born hairless.

Mexican, Canadian & American Hairless Breeds

Although there are written accounts from the 1830's of a Paraguayan "scant-haired cat", the first properly recorded hairless "breed" was the now extinct Mexican Hairless (also called the New Mexican Hairless). In 1902, a couple from New Mexico received two hairless cats from local Pueblo Indians. It was claimed that these were the last survivors of an ancient Aztec breed of cat. The Mexican Hairless cats were litter-mates and noted to be 25% smaller than local shorthair cats. They were normally whiskered and seasonally coated, growing a ridge of fur down the mid-back and tail during the colder seasons. The male, not yet sexually mature, was killed by dogs and the owners searched for a hairless mate for the female. In fact the loss was avoidable. The female could have been bred to similarly shaped domestic cats and the offspring back-crossed to their mother to re-establish the hairlessness trait. The female cat was sold as a pet and possibly exported to Britain or continental Europe in 1903 where she was exhibited, but apparently not bred. Even in 1902, enough was known about livestock breeding to have made this feasible. They resembled the modern Sphynx but were less extreme in face shape. There is the (remote) possibility that some later occurrences of random hairlessness trace back to this female since pet cats were not spayed in the early 1900s.

In "The Book of the Cat" (1903) Frances Simpson reproduced a letter written by E J Shinick to Mr H C Brooke regarding a pair of hairless cats which had come into Mr Shinick's possession. Brooke commented "A most extraordinary variety, of which next to nothing appears to be known, is the hairless cat, and we cannot do better than quote in extenso the description given by the owner of what, if his surmise should unhappily prove to be correct, was the last pair of these peculiar animals, a portrait of which we give. We can only add, while deeply regretting that Mr Shinick did not mate his cats, the earnest hope that we may hear that he has discovered the existence of other specimens."

"In answer would say my hairless cats are brother and sister. I got them from the Indians a few miles from this place. The old Jesuit Fathers tell me they are the last of the Aztec breed known only in New Mexico. I have found them the most intelligent and affectionate family pets I have ever met in the cat line; they are the quickest in action and smartest cats I have ever seen. They are fond of a warm bath, and love to sleep under the clothes at night with our little girl. They seem to understand nearly everything that is said to them; but I have never had time to train them. They are marked exactly alike - with mouse coloured backs; with neck, stomach and legs a delicate flesh tint. Their bodies are always warm and soft as a child's. They love to be fondled and caressed, and are very playful; will run up and down your body and around your waist like a flash.

"Nellie" weighs about eight pounds, and "Dick" weighed ten pounds; but I am sorry to say we have lost "Dick". We have never allowed them to go out of the house, as the dogs would be after them. They were very fond of our water spaniel, and would sleep with her. "Dick" was a sly rascal, and would steal out. One night last year he stole out, and the dogs finished him. His loss was very great, as I may never replace him. The Chicago Cat Club valued them at 1,000 dollars each. They were very anxious for me to come on with them for their cat shows, but I could not go. They were never on exhibition; as this is a small city, I feared they would be stolen. I have made every endeavour to get another mate for "Nellie", but have not been successful. I never allowed them to mate, as they were brother and sister, and I thought it might alter "Nellie's" beautiful form, which is round and handsome, with body rather long. In winter they have a light fur on back and ridge of tail, which falls off in warm weather. They stand the cold weather the same as other cats. They are not like the hairless dogs, whose hide is solid and tough; they are soft and delicate, with very loose skin.

"Nellie" has a very small head, large amber eyes, extra long moustache and eyebrows; her voice now is a good baritone, when young it sounded exactly like a child's. They have great appetites, and are quite dainty eaters - fried chicken and good steak is their choice. Have never been sick an hour. The enclosed faded picture is the only one I have at present - it is very lifelike, as it shows the wrinkles in its fine, soft skin. "Dick" was a very powerful cat; could whip any dog alone; his courage, no doubt, was the cause of his death. He always was the boss over our dogs. I have priced "Nellie" at 300 dollars. She is too valuable for me to keep in a small town. Many wealthy ladies would value her at her weight in gold if they knew what a very rare pet she is. I think in your position she would be a very good investment to exhibit at cat shows and other select events, as she doubtless is the only hairless cat now known. I have written to Old Mexico and all over this country without finding another. I would like to have her in some large museum where she would interest and be appreciated by thousands of people." E J Shinick, Albuquerque, New Mexico, February 3rd, 1902

According to Katharine L Simms in "They Walked Beside Me" (1954): "Only in Mexico is there a cat at all different from all other cats, and even he is the same in size and boen formation. But he is completely furless except for a ridge of hair down his spine. In that country also is the chino, or hairless dog, with blue-grey skin matching the Mexican cat. Maybe it is too hot in Mexico for fur or hair to be bearable, though our furry Indian and South African cats thrived in 100F in the shade." At the time Simms wrote that comment, the Mexican Hairless was already long extinct.

The illustration, from Charles Henry Lane's book "Rabbits, Cats and Cavies" (1903) is a portrait of a Mexican Hairless Cat called "Jesuit" that belonged to the Hon. Mrs McLaren Morrison. It was the only specimen the author had been shown and he believed it to be the only one ever exhibited in England. Most likely this was Nellie, bought as a pet and exhibited under a different name.

Sadly, the Mexican Hairless was lost through lack of a breeding programme. There was reputedly a pair in Europe, but whether these were genuine Mexican Hairless or a new mutation was unproven. In 2006, it was claimed that new examples of the Mexican Hairless had been found. This remains to be confirmed. A true Mexican Hairless cat grows a ridge of fur along the spine in winter.

Also in 1902, a breeder of blue Persians wrote to the magazine "Our Cats" that his cat "named Flossie had five most beautiful kittens, two light, three dark, with splendid heads. These all had lovely coats, but suddenly we found in the nest a perfectly light-blue kitten, all wrinkles, with a face like a monkey. The skin is blue, perfectly smooth and clean." Most likely the kitten did not surive long, or may even have been destroyed (at that time, the fate of most kittens that did not meet the standard). There have since been anecdotal reports of hairlessness occurring in Persians.

Hairless kittens (Bald Cats) appeared in in France (1932) but failed to thrive. In April 1935, the magazine "Vie A La Campagne" (Life in the Country) carried pictures from a 1932 cat show in Paris which had featured two hairless cats called "le chat nu" (the naked cat) shown as curiosities by Professor E Letard. The naked cats had been born to two different domestic females in the same household in 1930 though both died without reproducing in 1931. This suggests a degree of inbreeding allowing a recessive gene to be expressed. Some later reports refer to the French Sphynx being "resurrected" , but this would refer to the resurrection of hairless cats in general, not to a French strain. The French Sphynx (Le Chat Nu) never became an established breed in its own right.

Vie A La Campagne also reported the occurrence of a hairless kitten born to a shorthair female in Fêz, Morocco as well as occasional sightings of hairless cats in parts of Western Europe. The Journal of Heredity had two pictorial features of hairless cats. One (1936), nicknamed the "cat-dog", was born to a housecat in Wilmington, North Carolina. It was apparently born with open eyes, no whiskers and a precocious ability to crawl (characteristics said to occur in modern Sphynx cats). In 1938, veterinary professor E Letard reported two hairless kittens born to two Siamese cats in Paris, France but this may have been a re-reporting of the 1930s cats. The other Journal of Heredity report was of three hairless kittens born to a Siamese in Paris in 1950. The other six kittens in the litter were normally-furred. The hairless Siamese kittens were examined over several months by Professor Letard and reported to have whiskers and varying degrees of hairlessness; also the amount and type of hair changed during their first six months. When they were interbred, three more hairless kittens were produced, but there are no records of further breedings using these hairless cats so the mutation was lost.

The letter From Henry Sternberceh of Wilmington, N. C. to The Journal of Heredity in 1936 titled 'A "Cat-Dog" From North Carolina Hairless Gene or "Maternal Impression"?'

Hairless Cat Or Cat-Dog: Three views of an abnormal kitten which appeared in a litter of four, only one of which was normal,—two of the others being short tailed. The genetic nature of this variation is unknown, but it has a striking resemblance to some of the genetic hairless forms in rabbits and mice.

Around the middle of August, 1936, a curious litter of kittens was born to a perfectly ordinary appearing pet cat, belonging to Mrs. Annie Mae Gannon, of Wilmington, N. C. Of the entire litter, only one of the kittens is perfectly normal in appearance - the other three being freaks. One of the cats has no tail at all; another has only a stub of a tail. But the extraordinary member of this feline family is the fourth—well, we can hardly call it a cat - so for want of a better name, we'll call it a "Nonesuch."

It is said that before the kittens were born, the mother cat was often engaged in fights by a mixed-breed dog in the neighbourhood, and on several occasions was badly frightened by the dog. This is about the only plausible explanation as to why the "nonesuch" is so unusual in appearance. In fact, this little animal - now about two months old – is about the queerest looking creature one could hope to set eyes upon. Its face is that of a black, white, and yellow spotted dog. Its ears are quite long and sharp pointed. It has the short whiskers of a puppy. The hind legs are amusingly bowed. It has a stub tail. What makes the nonesuch even more unusual appearing is the short smooth dog hair all over its cat-like body.

From the very moment of its birth, which was about twelve hours after the rest of the litter, the nonesuch was surprisingly independent in its actions. It was born with its eyes open, and was able to crawl a little - two characteristics quite unknown to new-born kittens. The nonesuch acts both like a cat and a dog. While it makes a noise like a cat, it sniffs its food like a dog. Nothing delights the nonesuch more than gnawing a bone in a very dog-like manner. When resting, little nonesuch places its paws straight out in front just as a dog would do. The little creature doesn't relish playing with the rest of its family, being entirely contented in stretching out and watching the others frolic about.

The Editor replied:

Geneticists would be more inclined to ascribe the appearance of the unusual animal described above to the action of a recessive mutation than to the ancient doctrine of maternal impressions. If the curious kitten does represent a mutation, it is one of no little genetic interest, as offering a further parallel between mutations in the cat and the rabbit. (See Keeler and Cobb, Journal of heredity 24 :181-184. May 1933). To judge from Mr. Sternberger's pictures and the description, "Nonesuch" must rather closely resemble the Rex rabbit. It was hoped that it might be possible to obtain "None-such" and test the matter genetically. Unfortunately his owner is reported to feel that this unusual creature should be so valuable for museum or sideshow purposes as rather to put it out of range of genetic experimentation. In a later letter from Mr. Sternberger we learn that all the other members of the litter have died, so that there seems little hope of being able to do more than record the occurrence of this odd form.

In 1938, Professor Etienne Letard (Professor at the National Veterinary School of Alfort (Seine) France) replied in the Journal of Heredity in a letter titled 'Hairless Siamese Cats'

Hairless Siamese Kittens And Their Parents: Two views of hairless Siamese kittens twelve hours old, and their parents. All of them are hairless though one has a thin coat of short hairs. Note the fur distinctly visible on one of the kittens. This is especially thick on the ears and in the axes of the limbs. It disappears in a few days, being followed a short time later by another transitory coat.

The two accounts of "Nonesuch", the alleged cat-dog hybrid in the Journal (March and September, 1937), have greatly interested the writer because he has had an opportunity to study a startingly similar variation in Siamese cats. The accompanying photographs show the appearance of the hairless cats, whose resemblance to "Nonesuch" is obvious. The origin and description of this hairless strain follows. A pair of Siamese cats, perfect in type with normal hair and coloring, produced from time to time one or two hairless kittens in a litter consisting otherwise of normal kittens. From these periodically appearing hairless individuals we have been able to create a strain of hairless cats, which we believe to be entirely pure.

"Carrier" And Naked Siamese Cats: On the left is a normally haired Siamese cat, which mated to a normal-haired male produced hairless offspring. She thus carries the recessive hairless gene. At right a mature hairless Siamese cat, the type of this recessive mutation. Note that the vibrissae ("whiskers") are normal. The whiskers of some hairless mammals are also affected.

If one mates one of the two individuals who have produced this mutation, with other normal Siamese cats, a hairless kitten has never been produced. Only the mating of the two individuals in question produces the mutation. The crossing of a hairless animal with other normal individuals has never produced a hairless cat. We have mated two hairless cats, brother and sister; three hairless kittens were the result. With the exception of unforeseen circumstances which would have to be studied, the "hairless" can therefore be considered a type governed by the Mendelian law with hairlessness recessive to normal coat. Thus we find ourselves in possession of a strain, apparently already stable, which might be the origin of a distinct race, resuscitating the ancient race of so-called Mexican hairless cats, which is believed to be extinct.

It is imperative to mention that, though certain specimens are completely hairless, others have a slight down on their bodies. This down is subject to periodical changes, apparently closely connected with seasonal variations in temperature. Strange as k may seem, the young ones which grow into hairless cats are not so at birth, but have a growth of hair, less dense, however, than normal. A transitory pelage in young hairless rats has also been reported [Wilder, W., Et Al. A Hairless Mutation in the Rat. Journal of Heredity 23 :481- 484. 1932] The fact that the typical pattern of the Siamese cat is controlled in its development by temperature [1. Iljin, N. A. and V. N. Temperature Effects on the Color of the Siamese Cat Journal of Heredity 21 :309-318. 1930] may have a significance in this connection. This growth is most marked on the ventral surface and in the axils of the limbs. Between the tenth and fourteenth day after birth this juvenile hair has disappeared, and the "hairless skin" has become reality. The skin remains bald for several days and this is followed by another growth of hair. When the kitten has reached the age anywhere from eight to ten weeks it is covered with an abundant growth of hair which gradually disappears, until at the age of six months the final stage of adult nakedness has been reached; either the skin is completely hairless, or covered with a slight down, subject to seasonal changes.

The fact that this mutation was observed in animals which have always lived in Paris, proves again that it is not always in special environments that one has to search for visible variations, and emphasizes again the random nature of spontaneous changes in inherited characters which appear to be one of the basic mechanisms of organic evolution.

In June 1959, the Australian Post reported a hairless female cat called Sylvester. Sylvester was born in 1956 without fur, claws, whiskers or eyelashes. Her tail curled up at the end "like a possum's" and she curled it around objects. The cat (which appears to be a black with white locket and boots) was owned by Melbourne Grammar School student Richard Rigby of Langwarrin who reported Sylvester was dog-like in her ability to obey commands. Sylvester was one of four kittens in the litter and was kept warm by one of the other kittens. That other kitten, a male, was later mated to Sylvester and in 1959, Sylvester had 3 fully furred kittens. It was reported that Sylvester was not bothered by fleas and that she wore a woolly coat to keep her warm. The lack of claws suggests a general failure to produce keratin. Nothing further seems to have been heard of this mutation.

In his book “Just Cats” (1957), French cat-fancier Fernand Mery wrote “It is true that completely naked cats also exist: cats without fur, among which we have succeeded in determining a strange mutation linked to a recessive gene. Did the race of hairless cats actually exist in Mexico? Did it originate from the short-haired cats of Paraguay? This is not beyond the realms of possibility, as these hairless cats are not initially bare; they do not come into the world so, as Andre Sécat has pointed out. Initially they have a covering of down, which falls out after the first week. Afterwards there is another growth of down, which lasts for two months: time for the kittens to be weaned and sufficiently developed to survive. In its turn, this thin coat falls out during the next few weeks. When the cats have attained the age of six months, they are then, but then only, hairless cats, perfectly smooth-skinned. Are they beautiful? That is a different matter. But should you be tempted to possess one, it would be useless to look for it on the market. There are no hairless cats professionally bred. They are simply a curiosity of creation."

It was reported (in 1966, probably referring to the 1930s kittens) that Professor Étienne Letard of L'Ecole Nationale Vétérinaire d'Alfort in France had "resurrected" the breed of bald cats and it was noted that there were a few examples in Europe and America. The cats were reported as not born completely bald. The kittens had very light hairs which have scarcely thickened by the growth of a slight down during the first two months. After the kittens are weaned, this down falls away to leave them completely smooth. At the time, they are described as sensitive to cold, unaesthetic and not much admired by cat lovers and having only a technical interest. The report noted that the mutation had been fixed, but the breeding of bald cats was a flirtation for the specialist and did not have a great future.

The modern Sphynx (Canadian Hairless) may be advertised as the hairless cat from the scrolls of antiquity, but it derives from Canadian cats of either the 1960s or 1970s. It has variously been known as the Moon Cat, Moonstone Cat or Canadian Hairless and may be spelled either Sphynx or Sphinx, though the former spelling is more common. The history of the Canadian Sphynx is not continuous as the original bloodline has been lost, but the breeding program was restored when more hairless kittens surfaced later. The later cats were probably related to the earlier discovery, but there is no traceability.

The Sphynx's recessive gene mutation appeared more than once in Toronto, Canada but the cats were most likely related. Hairless kittens were discovered in Toronto in 1963 and it was established that the trait was due to a recessive gene. They were bred, but the breeding experiment was discontinued in the late 1970s. Though a number of breeders were working with these cats, the breed was not eligible for registration and many small breeding programs were started up, only to vanish without trace a few years later. Inexperienced breeders produced unhealthy or poorly fertile cats, signs of inbreeding. In 1973, the Journal of Heredity ran a report on these hairless cats. In 1978, the last breeding pair of cats from that breeding program went to Holland. The cats were brother and sister and though the female produced a litter of kittens, she rejected them. They did not manage to produce any further kittens which suggests poor fertility/infertility due to severe inbreeding. What was needed, were further female Sphynxes to widen the gene pool.

Coincidentally, also in 1978 (some reports erroneously state 1973, probably based on the report in the Journal of Heredity relating to the earlier hairless cats), a litter with hairless kittens was discovered among street cats in Toronto. The mother giving birth to two further hairless female kittens in separate litters in 1980. Since the gene for hairlessness is recessive, both the mother and the two sires must have carried the gene. It is likely that the parents of those kittens were unrecorded progeny from the earlier, failed, breeding program. The two 1980s females were sent to the Netherlands to the same person who held the last of the 1970s strain. He attempted to breed the two strains together. The male refused to accept either of the two new females and was neutered. It was discovered that one of the females was pregnant by that sire, but she lost the litter and with it the genes of the last authenticated Canadian Hairless of the earlier strain. The Sphynx breed was therefore developed using Devon Rex. Devon Rex sometimes occur with sparse fur and in 2010 DNA analysis found that Devon Rex and Sphynx are alleles of the same gene. Rather than being totally hairless, the modern Sphynx derived from Canadian cats and other genetically compatible spontaneously occurring hairless cats has a light peach-fuzz on the skin and sometimes fur on the tail-tip. Unlike the Mexican Hairless, it does not grow a ridge of fur during the colder seasons.

A further Canadian Sphynx appeared during the early years of the breed; this being a hairless male farm cat found in Western Canada. Though acquired by a Sphynx owner in Washington state, he does not appear to have contributed to the modern Sphynx line. Possibly he was genetically incompatible or otherwise unsuitable.

In 1970, two nude cats (later named Starkers and Baldy) were cared for at the Blue Cross Animal Hospital in London's Victoria district. The pair appeared in the Daily Mirror newspaper apparently in spite of its "no nudes" policy! In 1975 and 1976, Jezabelle, a tabby shorthair farm cat owned by Minnesota couple, Milt & Ethelyn Pearson, had given birth to two hairless female kittens - Epidermis (1975) and Dermis (1976). These were later used to expand the Sphynx gene pool. The Pearsons' farm cats bred freely and there were hairless kittens born in several litters, suggesting a mutation several generations earlier followed by a degree of inbreeding. A hairless male barn cat occurred in North Carolina, but there are no recorded offspring from this cat.

In 1984, the Journal of Heredity reported hairlessness in 10 Birman kittens born in England between 1978-1982. The hairless Birman kittens had short or absent whiskers and greasy skin. None survived beyond ten weeks of age, dying from various disease processes (possibly a metabolic or immune system disorder). This type of hairlessness was already associated with a lethal gene following a study in 1981. The hairless kittens were observed by a breeder in 1977 in Redcar, Cleveland, UK in litters of pedigree Birmans with no previous history of hairlessness in the pedigrees. The stud was somewhat inbred, but this was not unusual for the breed. The female was mated to 2 different, but related males. The first stud fathered 7 normal and 1 hairless kitten. The second stud fathered 7 normal and 2 hairless kittens. A normal-furred female from the first pairing was mated to the second male and produced 3 normal and 3 hairless kittens. The 17 normal and 6 hairless kittens was consistent with a recessive mutation. When mated to an unrelated Siamese male, the original female Birman produced normal kittens. The condition was lethal with death usually occurring before 2 weeks of age. Affected kittens never grow more than a fine coating of down. Based on the longest surviving cat (a male, died aged 3 months), the skin is soft at birth but steadily becomes thickened and wrinkled. The few whiskers present are short, thin and crinkled. In the kittens that died before 2 weeks, there was also a brownish secretion accumulating around the nostrils and eyes, and under the chin (believed to be a secondary bacterial infection). A male Redcar hairless that survived to 3 months had defective, easily split claws. It died suddenly of no obvious cause, but had suffered persistent diarrhoea since weaning. This male had been completely hairless from birth apart from a few short, bent whiskers.

In 1986 (unconfirmed date) a hairless cat turned up at a New York, USA animal show. The owner claimed to know of a hundred more in various locations around the world. In 1986 a hairless female was discovered in a colony of freely breeding domestic shorthairs in Bloomfield, New Jersey, but the owner apparently would not allow this cat or its normal haired offspring (which would carry the gene for hairlessness) to be used in the Sphynx breeding program. In 1993, a mother cat with three normal-coated kittens and one hairless kitten was rescued in Westchester County, New York. The kitten, known as Gracie, proved to have a different mutation. She produced normal coated offspring when mated with a Sphynx. In 1995 a hairless male kitten was born to two long-haired parents in Tennessee and was incorporated into the Sphynx genepool. A hairless male from the White Mountains of Arizona was added to the Sphynx gene pool (date unknown).

Hairlessness has, allegedly, occurred more recently in Persian cats, a breed known for its long fur. In Persians, hairlessness was considered shameful; the existence of hairless kittens was therefore a closely guarded secret among those working with the affecting breeding line so that carriers could be eliminated from the Persian breed. Mutating genes have no respect for which breed they turn up in!

In 2004, the Cheops was apparently derived from Canadian lines of the American Cornish Rex. It has a very fine coat, approximately 1/8" long over the head, neck, back and sides and a slightly longer coat on the chest and hips, however this residual coat lacks the waviness of the Cornish Rex. The tail may have a tuft at the tip.

The Elf breed was initiated in 2006 with the first full hairless, curl-eared Elf being born in 2008. It combines the Sphynx hairlessness with the American Curl's ear conformation. Permissible out-crosses include non-pedigree domestic shorthairs. They have a sturdy, athletic build, are sociable, intelligent, inquisitive and people centred. Half-Elf cats e.g. furred Elf variants result from outcrosses to diversify the gene pool.

The Dwelf also combines curl ears with hairlessness, but adds Munchkin and Highlander (a bobtailed, curl-eared polydactyl breed) to the mix. These combine hairlessness, curled ears and short legs. Non-standard (long legged) Dwelfs may resemble the Elf breed.

Throughout the world there are still reports of hairless kittens appearing in litters of feral cats and house cats. Hairless cats found in domestic cat litters may still be used in the Sphynx breeding programme to strengthen and expand the gene pool. Some of them are producing extremely hairless offspring, suggesting that several genes may be involved, not just a single simple mutation. Others, like the much more recent Peterbald (discussed later), prove incompatible with the Canadian Sphynx because they have a different mutation. In the USA, hairless cats have been found in North Carolina, Minnesota, Texas, Arkansas and Indiana. In Canada they have turned up in Toronto and in Western Canada (no precise location given). They have also occurred around the world although to date only the Canadian, Russian and Hawaiian mutations have given rise to distinct breeds.

Russian Hairless Cats

Hairless cats were reported in England in 1981 and 1984, but for many years, the Canadian-bred Sphynx was unopposed as the sole hairless cat breed. This changed with the appearance of the Don Sphynx (Don Hairless, Russian Hairless, Don Bald Cat, Donskoy/Donsky) in 1987. Donskoy Sphynx originated in the small town of Rostov-on-Don in Russia. The foundation female of the Donskoy Sphynx and the related Peterbald was a blue tortoiseshell cat named Varya, who was rescued by Elena Kovalyova. At the time it was thought that hairless Varya had lost her fur through illness, but in pite of anti-fungal treatment the fur did not grow and Varya proved to be in good health. Around 1989, Varya was bred to a neighbouring tomcat and produced several hairless kittens. One of those kittens, a black female called Chita, went to Irina Nemykina's "Myth" cattery. Nemykina's records showed that the mutation was dominant. The hairless cats in the Myth aattery were bred to European Shorthairs and Domestic Shorthairs and these became the foundation cats of the Donskoy Sphynx breed.

Matings of the Donskoy cats with Oriental/Siamese in St.Petersburg and Moscow in 1993 created an oriental type of hairless cat known as the Peterbald. Though unpopular in Moscow, they were popular with St.Petersburg breeders. The first Peterbalds were born in January of 1994 from a mating between an Oriental tortoiseshell female called Radma von Jagerhof with a brown mackerel tabby Donskoy Sphynx male called Afinogen Myth. Afinogen Myth had a light bone structure and a wedge-shaped head, making him a good choice for breeding with Oriental cats. He was also mated with Russian Blues, producing Donskoy Sphynx. Some of the more elegant kittens from the Afinogen Myth x Russian Blue matings were incorporated into the Peterbald breeding programme and became foundation cats.

The Russian standard for the Donskoy Sphynx requires solid, medium size cats with a short, wedge shaped head, large ears, noticeable eyeballs and a flat forehead with numerous vertical wrinkles spreading in horizontal lines above the eyes. The whiskers range from thick and curly to snapped or absent. The toes are unusually long in appearance. The last 3 centimetres of the tail tip may be covered with soft, dense, close lying, slightly curly coat. The skin is describes as elastic and wrinkled on the head, neck, under the legs and in the groin. Young cats (under 2 years old) may have short fur on the muzzle, cheeks and at the base of the ears and in the winter, the whole body may be covered with a fine coat. Donskoy Sphynx kittens may be born with wavy rex coats and a bald spot on the head, but the required distinctive sign of a newborn Donskoy are curly whiskers.

The heterozygous offspring of matings between the Donskoy Sphynx and a furred outcross can be variable in appearance: some heterozygous offspring have a residual curly coat at birth and this varied from short velvet to unusually fine normal length hair. Generally there is a bald spot on the crown of the head. As the heterozygous kittens mature, the hair follicles died except for those at the points. These furred kittens shed their coats between 2 months and 2 years of age. Other heterozygous kittens have thick curly (rex) hair and remain coated throughout their life; these variants are known as "brush". The mutation also affected the conformation and most "brush" variants lack breed's characteristic short wedge face. In the second generation (i.e. shed x shed or shed x brush) a third type appeared: completely hairless at birth, wrinkle-skinned and often without whiskers. The hairless and velvet Donskoy Sphynx tend to grow more slowly than their furred siblings.

The Donskoy Sphynx is now being seriously bred in the USA and its breeder suggested using it to found an experimental Hemingway Sphynx which would be a variety of hairless cat with extra toes. This is now calledthe Dossow Cat.

In 2005, the Ukrainian Levkoy Cat, a fold-eared naked cat, was created using the Don Sphinx and Scottish Fold. The Ukrainian Levkoy is less extreme in body and face type than the Don Sphinx (the face is wider and ronder) and the ears do not fold tightly to the skull as in the Scottish Fold, but stand out from the head and fold closer to the tips. It also occurs in velour and pric-eared forms.

The Peterbald (St Petersburg Hairless) is another Sphynx-like Russian breed derived from the same female, but with an oriental-type body. It originated as cross between Don Sphynx and Oriental-type household pets in St Petersburg. Some matings of Don Sphynx to Oriental/Siamese occurred in St.Petersburg and in Moscow in 1993. The first true Peterbalds were born in January 1994 using a tortie oriental female and tabby Don Sphynx with some Oriental traits. The Don Sphynx was also bred with Russian Blues to produce more Don Sphynx, but some of these offspring were used in the Peterbald breeding program. Like the Don Sphynx, the Peterbald is now also bred in the USA. If a Peterbald (or Don Sphynx) is crossed with a Sphynx, normal-coated kittens result because the hairlessness is caused by different genes.

Recent Mutations and Developments

Hairless cats still pop up out of nowhere due to mutation or hidden recessives inherited generations back. Many are treated as oddities and are neutered because the trait is seen as detrimental. Elsewhere, the new occurrences may either be used to expand the gene pool of an existing hairless breed (if found to be genetically compatible) or used to create a whole new breed (if genetically different). In 2002, the Hawaiian Hairless (or Kohana Kat) was reported. These cats were claimed to be the only completely hairless cats, since they lacked hair follicles and had a skin texture like rubber. The Hawaiian Hairless originated from a feral litter in Hawaii, and were allegedly due to a gene which masked out the dominant gene for full-coatedness. Unlike the other hairless breeds where the mutation affects the function of the hair follicles, this muttion allegedly caused the absence of hair follicles. There were other, unconfirmed, reports that it was the result of mating a Donskoy Sphynx to a Canadian Sphynx and the interaction of the 2 different genes. In 2010 it was confirmed by DNA analysis that the Kohana Kat had the same hairlessness mutation as the Sphynx, with other effects being due to other genes in the mix, and it was not a new mutation. By this time the Kohana Kat had all but died out due to reproductive problems and other health issues that may have been due to inbreeding.

DNA analysis in 2010 also found that Sphynx and Devon Rex are different mutations of the same gene. The relationship between these mutations from most dominant to most recessive is: Normal Hair >> Sphynx >> Devon Rex

This is a hairless stray/feral domestic cat photographed in south-eastern Yemen where it was loitering on a building site and apparently chewing cable (a condition known as pica that is more common in Siamese/Burmese cats). It has a peach-fuzz of fur, with more fur on the extremities, suggesting a hairless mutation. The little colour visible (on the tail and near one ear) indicate it is ginger-and-white. The battle-scarred ears indicate a cat that has been in frequent fights; the puffiness of the face indicates a serious infection or tumours and the lack of fur/pale colour generally puts the cat at risk of skin cancer. The shortened tail could be a natural and relatively common bobtail mutation or the result of an injury. The puffiness around the eyes indicate further problems and the skin appears thickened which may be due to chronic mange or infection. All in all, the cat is in a sorry state.

 

A Sphynxkin was also reported as an intended fully hairless Munchkin/Sphynx crossbreed, but never materialised. The Mynx was reported to be a Manx/Sphynx crossbreed and was strongly discouraged because of side-effects of the Manx gene. The "breeder" was apparently attempting to obtain foundation cats, but there has been no further news of this "breed" so presumably it was not developed further. Another hybrid of Sphynx and Munchkin has produced the Bambino (Italian for "baby" and alludes to their mischievous personalities) with a wedge-shaped head, wide set eyes, short, squarish muzzle and lynx-tipped ears set well onto the top of the head rather than flared outwards. It is a muscular, medium-boned cat. The coat varies from hairless to peach-fuzz and all colours and patterns are allowed. Bambino Long-Legs variants occur.

The Mythical Hairless Breeds

Finally two "breeds" which have caused a stir of quite the wrong kind are the Egyptian Hairless Cat and the Chinese Hairless Cat Neither breed actually exists although numerous people have either tried to obtain one or claim to "know somebody who has one".

The root of the mythical Chinese Hairless cat might be Monsieur Patrick Challan, a French antique breeder who apparently attempted to revive hairless cats as a breed (undated report). He speculated that his cats were Sphynx cats, which lived in China in ancient times and which were descended from a liaison between a cat and a "beautiful midget hairless dog". He stated, by way of support to these claims, that his five nude cats (chats nus) were never afraid of dogs and approached them in a friendly, playful manner. Monsieur Challan's research apparently found that bald cats had appeared in the writings of a few English authors and that they had been sighted in Canada just after that country was conquered by the British. This historical link, never mind the hysterical dog-cat claim, resulted in Monsieur Challan being offered up to $50,000 for his nude cats. These offers were rejected by Challan who wanted to breed the cats himself. He may not have resurrected the hairless cat breed, but he seems to have created a mythical Chinese Hairless Cat myth. I can find no mention of a Patrick Challan in Sphynx literature, although a Patrique Challain of Paris bought 5 Sphynx kittens from a Dutch breeder in 1983.

The "Egyptian Hairless Cat" was invented around 2001 by the TV show "Friends" and mistakenly reported as fact on some veterinary websites and on usenet. The show depicted it as hypoallergenic. Hairless cats are not hypoallergenic since the allergen is in the saliva and dander, not the fur itself. It was irresponsible of the show to mislead viewers into believing the hypoallergenic myth as well as creating a belief in a non-existent cat "breed". Although the name "Sphynx" might suggest an Egyptian origin, there are currently no hairless varieities originating from Egypt.

There is also no such breed as the "Chinese Hairless Cat". It appears to be no more than a garbled version of the Egyptian Hairless which has possibly been confused with the Chinese Crested (or Hairless) Dog (which does exist) or the legacy of Patrick Challan. Having said this, no doubt someone somewhere will spot a marketing opportunity and create breeds by these names!

FUTURE HAIRLESS?

Potentially, any of the hairless breeds could be crossed with any other breed of cat to produce hairless cats with bobtails, no tails, extra toes, different ear shapes, different body conformations (e.g. the stocky conformation of the Persian) and other combinations of physical traits. Whether these are desirable is another matter entirely and many experimental cross-breedings are not pursued as breeds. In 2006, TICA's Genetics Committee proposed to clamp down on the trend of mix-and-match breeding.
