Marketa Vondrousova's Sphynx cat kept her husband at home until the Wimbledon final

Well, for me, it is nice to know that the Wimbledon champion likes cats even if she bought a hairless one - a Sphynx - which is a little controversial as some people think that some cat breeds should not have been created because they are too unnatural and require specialist care as does the Sphynx. It is called torture breeding in Germany.

It is nice that Vondrousova's husband stayed behind in the Czech Republic to care for their cat Frankie while she was battling her way to the final.

The couple decided that he should come over for the final and arranged for a cat sitter to take his place. It worked out for them.

Sphynx cats are normally indoor cats as UVB light can harm them as they have no skin protection from fur. 

Also, they need cleaning regularly as the oils from their sebaceous glands sits on their skin and not on the fur where it protects it and makes it feel silky. 

When the oil is on exposed skin it attracts grime. The skin becomes dirty and needs regular cleaning. The Sphynx ears also need regular cleaning as they become.

This is a highly active, monkey-like cat breed. And they are intelligent. They've described affectionately as 'part monkey, part dog'!

Despite having almost no fur, they do have some; a downy soft coat like you see on peaches! This is why the breed has coat markings. There is also the fact that the pigment producing cells in the skin follow the pattern so we see coat patterns on this hairless cat which is a little strange.

Frankie has a brindled-like coat. The whiskers are typical of a Sphynx; broken, short and curly with some missing. This another aspect of the cat's unnaturalness. The whiskers are an important part of a cat's anatomy.

Photo of a Sphynx cat doing Pilates (plus a bit about the breed)

You can always bank on a Sphynx cat to look interesting in a photograph. This is one such example. It's obviously set up but done well. It caught my eye. The eye is immediately drawn to the webbing between the toes. The hairlessness of the sphynx cat shows us what is typical of all domestic cats, namely the webbing between the toes. This simply must be an adaptation for swimming. Domestic cats are pretty good swimmers which goes against the views of a lot of people that "cats don't like water". They don't mind water. Their wild cat ancestor does a lot of hunting near watercourses. These are good areas for prey animals.

This Sphynx cat looks nice and clean. You probably know by now that Sphynx cats have a problem with becoming grimy because the sebaceous glands in their skin which would normally deliver oil to the individual hair strands, instead deliver it to the skin where it attracts dirt. That is why they say that you have to clean a Sphynx cat with a damp cloth regularly. I've also heard that they can smell a bit because of this.

And of course, you can't let them wander around outside so they are always going to be full-time indoor cats. Perhaps a catio would be ideal but you would have to make sure that you don't let blazing hot Californian sun shine directly into it if your Sphynx cat likes to spend time on a shelf in the catio.

Sphynx cats are known to be monkey-like. They are good climbers and intelligent and mischievous. Of all the breeds, they are in the top echelon of intelligence it is said. Although you have to take cat breed intelligence comparisons with a pinch of salt. It is impractical, if we are honest, to compare the intelligence of the cat breeds. It's impossible to compare the intelligence of an adult domestic cat with that of a four-year-old child as well. People try to do it but I disagree with the idea.

RELATED: Cat Intelligence.

Sphynx cats are a bit like Marmite. You either love them or loathe them. They are certainly eye-catching. They are the most photogenic of all cats other than the supra-large Maine Coons.

This cat is not entirely hairless. For a start, they are covered with a very short down that is almost imperceptible to the eye and can hardly be felt. There may be a small amount of hair on the tip of the tail and the extremities i.e. the points may have a soft short dense hair. Sometimes you see them with crinkly broken whiskers.

You will probably see somewhere out there in the world a hairless cat that is not a Sphynx cat and neither is the cat a purebred cat. They are still out there but of course extremely rare. They have been around for thousands of years and the spontaneous genetic mutation which causes the hairlessness sometimes pops up. You will see hairlessness in dogs, rats mice and other animals.

RELATED: Do Sphynx cats smell?

There are various stories about the beginnings of the Sphynx cat breed. Gloria Stephens thinks that her research has produced the best example. She says that in 1974 in Wadena, Minnesota, USA, a female cat called Jezebelle gave birth a hairless kitten called Epidermis. She was female. The following year Jezebelle gave birth to Dermis another hairless female. They were sent to Kim Mueske of the Z. Stardust cattery in Tigard, Oregon.

The classic Sphynx origin story is that in 1966 in Toronto Canada a domestic cat by the name of Elizabeth produced a hairless kitten named Prune. And in 1978, 3 hairless kittens were rescued from the streets of Toronto. These three kittens may be the foundation for the Canadian sphynx. There are other stories. I think I will stop as it is confusing. Hairless cats have popped up in Paris, France and other parts of the world. Some said they were the offspring of Siamese cats. Others said that they were stray cats.

There is one thing that is certain which is that the first Sphynx cats that became the foundation cat of this breed were non-purebred cats, simply random-bread cats from which they were selectively bred to produce this popular and interesting breed.

Are hairless cats really envious of longhair cats?

The title is amusing when you see the video. This couple of hairless cats are so committed to grooming the white Persian that you would be forgiven for believing that they were envious of her hair. I don't think it's true. The emotion of envy is a human one. The desire to groom a friend of yours, if you are a cat, is a strong motivator. You probably know that it is called allogrooming. 

If a cat is envious of another cat because they have hair, the cat who experiences the emotion of envy must recognise the fact that they don't have hair. In order to recognise that simple fact they have to be self-aware. They have to be self-conscious. And this is one of those massive debates. People aren't sure whether cats are self-conscious. 

This means a person or animal: recognises themselves objectively and can assess themselves compared to others. At the moment people are unsure that cats can do this. They probably can't. If that is true then it confirms what I have said that cats don't feel envy and these two hairless cats are not envious of this beautiful Persian cat's fur.

Some people say that it is a form of dominance but I don't really believe that. It's a question of friendly interactions. Cats do it to people all the time as you know. They do it for the same reason: friendliness. 

This couple of Sphynx cats are certainly committed. They carry on even when there is a miniature crash helmet on the head of the Persian. I find that a bit odd, I confess. Surely these hairless cats recognise that they are no longer licking a cat's hair? 

But apparently not. It looks as if the behaviour is entirely instinctive. Perhaps they lick the crash helmet because it's a bit like licking their own bodies. I think that is the reason behind this behaviour. They accept the hairlessness of the helmet; no questions asked.

Note: This is a video from another website which is embedded here. Sometimes they are deleted at source which stops them working on this site. If that has happened, I apologise but I have no control over it.

Thug jailed for stealing two hairless cats and other items

NEWS AND COMMENT-BARNSLEY, UK: He is a father which I think compounds the problem. His name is Jordan Reynolds-Walsh and he's been convicted of burglary. He targeted two properties in the Goldthorpe area of Barnsley, UK.

A woman was told by the police that her property had been broken into. She is the owner of two Sphynx cats. When she returned to her home she soon noticed that her two cats were missing as well as white goods and power tools.

The next day she saw two men carrying large bags from a house in Cooperative Street, Barnsley, to a Carr House flat. The police searched the Carr House flat. They found power tools and bank cards in the name of the victim. They also found the burglar's ID amongst the items.

They found one Sphynx cat in the bathroom and the second had been hidden behind a bath panel. Both were returned to their owner. He had left a can of larger with his fingerprints on it in the property! That convicted him.

Reynolds-Walsh had burgled another property earlier. He had ransacked a house in Cooperation Street on July 22 and stole a variety of items including a ring with sentimental value. He had smashed the door to the home. The repair charges were £1000.

Reynolds-Walsh admitted his crimes. The lawyer defending him said that he had lost his job as a scaffolder (scaffolder's are the worst form of human life by the way). His life had "spiralled out of control" and he had turned to drink and drugs. That was the statement in mitigation against his sentence which was two years and two months in prison.

The interesting aspect of this story is the theft of two rare purebred cats. On purely financial level they were worth stealing because the combined value is probably around £2000 or thereabouts. The difficulty he had, in his carelessness, was how to deal with them. How to care for them pending their sale? And because they are very noticeable it would be very difficult to sell them. It could be done but I would think that it would raise suspicions in the purchaser.

And of course they would be vulnerable to harm as they were in the care of this criminal for a while who had no idea how do care for them. The story does highlight, however, the value of purebred companion animals. I suspect that many more valuable pets are stolen than people are aware of in the UK. Dogs are particularly at risk.  The UK has deteriorated in recent years in respect of an increase in crime thanks largely to the ineffectiveness of the police and the lack of trust they have engendered through their own well-publicised criminality.

I live near Richmond Park, a famous and beautiful park in Surrey. There is currently a poster attached to the railings at Ham Gate, one of the entrances to the park that I frequently use. The poster contains a plea to find a dachshund dog lost their a while ago. It is highly likely that the dog was stolen. Dog owners let their dogs off the lead in the park which can be irresponsible because they harass the deer. There is also the risk that if they end up out of sight of their owner, which is entirely possible, they can be stolen by another user in the park who casually befriends the dog and then takes them home.

Katie Price gives away her kids' remaining Sphynx cat

People ask whether Katie Price has a Sphynx cat. Well, there was a time when she had 2 Sphynx cats but no longer. It is hard to keep pace with the acquisition and abandonment of animals that live with Katie Price and to be perfectly honest I can't say I care about her but I do care about the animals. 

She impulsively adopted two Sphynx cats some time ago. The black Sphynx cat was named Hagrid while the standard coloured Sphynx cat was named Dobby according to The Sun newspaper. They have an Instagram account (don't they always :-? ). The photograph on this page is from that account.

Hagrid and Dobby - Price's former 2 Sphynx cats. Photo: Instagram

She gave away Dobby about years ago and The Sun now reports that she has just given away another of her children's pets in giving Hagrid to a friend from the local stables where her £10,000 horse is kept. The reason? It's because her so-called 'Mucky Mansion' is being refurbished as part of a reality TV programme, as I understand it. Therefore she is living out of a suitcase with her current partner.

RELATED: The wrinkly skin of hairless cats.

Katie's former boyfriend Kieran Hayler said that both the hairless cats were peeing everywhere around the home ('mucky mansion' seems correct) when he lived there. Dobby was relinquished because he couldn't get on with Katie's protection dog Blade. That would have caused peeing inappropriately.

And because there was cat urine everywhere the place stank of cat urine as it would (ammonia smell). And because of that she lit a candle to try and mask the smell. That caused a house fire apparently.

So that's the story of Katie Price's Sphynx cats. A disaster. What is ironic is that when she lived with her former husband Peter Andre, he insisted that she had to keep the cats because they belonged to their two children Princess and Junior. Times have changed and now anything goes.

Katie Price has a history of self-indulgent adoptions of animals without proper preparation and budgeting to only find later that she hasn't got the skills or the finances to properly care for the animals in her charge.

If it is true that the hairless cats were peeing everywhere it would have been due to stress because they were marking territory to reassure themselves. And this points to a chaotic environment which was not calm enough. 

Also, Sphynx cats are quite hard to care for because they need to be full-time indoor cats and washed regularly as their skin becomes grimy due to the oils from sebaceous glands deposited on the skin. 

They look interesting which would have appealed to Katie Price but it's not all plain sailing. You have to know what you're doing and be committed. This appears to be beyond Ms Price.

The aptly named "Mucky Mansion" is certainly large. It's located in Sussex and she bought it for £1.3 million in 2014. It has nine bedrooms and three stories. There is a two-bedroom annexe, stables, tennis court a swimming pool and 12 acres of land. There are many reports about its rundown state. This probably is due to the fact that Katie Price did not have the budget to maintain the property. It appears that her earning potential has faded considerably as she becomes older and the public becomes weary of her antics.

Cold Sphynx cat looking like an old man in a doorway

This is a picture of a cold Sphynx cat bent over in a slightly strange position with an interesting expression and an overall appearance which reminds me of an old man with a bent back walking down a street or standing in a doorway on a cold winter night. Perhaps my imagination is running riot and perhaps I am anthropomorphising this cat too much. We nearly always anthropomorphise our cats. But look at the expression on his face. At the base of the page I explain why I think he has taken up this position.

It's a peculiar position and his owner says that he always does this when he's cold. And when I read that information I questioned what she was doing. Why did she allow him to get cold and then photograph him and upload the photograph to the Internet?

Would it not have been better if she had kept him warm? The trouble with that suggestion is that if she had kept him warm he wouldn't have looked like this. And she wouldn't have been able to take an interesting photograph of her cat. In turn, that would have prevented her uploading an interesting cat photograph to the Internet. You can see what I'm getting at. A problem for Sphynx cats is that they are very photogenic. You can get a lot of very good photographs of these hairless cats.

She let him get cold so she could get a good picture for social media consumption. Personally, I don't like it. I think social media is undermining cat welfare. And I'm including YouTube. All those funny cat videos are in fact videos of cats often being stressed and anxious. People don't like to discuss it but I refuse to let it go.

RELATED: Do Sphynx cats smell?

I don't want to be curmudgeonly but there has to be a balance between animal welfare and making some money on YouTube through advertising. That is the reason why people make funny cat videos. You can make more money on YouTube advertising through Google AdSense then you can through a website i.e. the written word. YouTube can be quite a good earner.

The problem is that the YouTube administrators have gradually, over the years, added to the amount of advertising on uploaded videos. They've absolutely maxed it out to the point where it can be irritating to watch a video because it is interrupted too much by adverts. I'm digressing.

RELATED: Are Sphynx cats hypoallergenic?

Back to the cat. Despite my criticism, it is an interesting photograph. I would say that the reason why he looks like this is because he's keeping himself warm over the warm air vent which is right in front of him! The photographer knows that.

It is hardly worth saying but Sphynx cats are hairless and therefore they feel the cold. You've got to keep your home warm. That's going to cost extra money. Sphynx cats require enhanced cat caretaking (bathing for instance) which is perhaps something that people don't take fully into consideration when they adopt one.

Unusual photograph of cat and caregiver

"Our tiny turtle is a papa to two cats; Pluto and Muffin. Pluto is a hyperactive furless cat and Muffin is a Scottish breed. This little family is my source of happiness.."

I like this photo. It is different. It made me look. It is a nice composition too. The words of the owner are above. He lives in an Asian country but not sure which one. The hairless cat is photogenic. Cats like to smell their owners! The scent of their caregiver is enjoyable to them. Initially it looked to me as if the cat was sniffing his eye. But no. The cat is licking his left foreleg while resting it on the man's face. Cool.

Looks odd but it's completely normal for a cat.

Hairless crested dog in bed with a Sphynx cat

An interesting photo: what appears to be a hairless crested dog and a Sphynx cat in bed together. I think it is the first time I have seen this. Two things come to mind (1) they can keep each other warm and (2) the owner must like hairlessness! You have to keep hairless cats indoors, which is unfortunate.

I do not know much about hairless dogs but I do know that with hairless cats you have to clean them regularly because the sebaceous glands produce oils which rather than being deposited on hair strands is deposited on the skin where it picks up dirt and grime. The sebaceous also have nowhere to go. And of course, you got temperature issues because a hairless cat in a very cold climate is not going to work for obvious reasons. 

You have to provide a coat but the advice that I have seen is that you should keep a Sphynx cat inside in cold temperatures. In hot temperatures there may be the possibility of sunburn so the general upshot is to keep hairless cats inside but what about dogs? It goes against the grain to keep a pet dog inside all the time and it is probably impossible to achieve.

Associated: A rare hairless opossum rescued in Texas goes viral. Now she’s getting a new wardrobe.

There is an accepted idea of the full-time indoor cat but is this model of cat caregiving accepted for the hairless domestic dog? What percentage of domestic dogs are kept inside full-time? I can't find an answer to the question but you will find an answer to the question of how many domestic cats are kept indoors full-time. It is quite a high percentage nowadays e.g. 40%, and the trend is growing in that direction in the USA.

The same problems of keeping a cat indoors all the time apply to a dog, perhaps more so. I think that you would have to find some way of taking your hairless dog outside safely perhaps using a skin care product to protect against sunburn or, in the cold, to wear a suitably adapted coat.

P.S. The cat is a bicolor. Is the pattern in the skin or within fine downy hair? I reckon the melanocytes in the skin, where the pigment is created, create the pattern in hairless cats. See: Picture of a black Sphynx cat.

Hairless cat poses like a celebrity starlet at the Cannes Film Festival

A hairless cat, probably a Sphynx, poses like a celebrity starlet at the Cannes Film Festival. A very strange photograph. Was it posed by the photographer by positioning his/her cat and rapidly taking the photo or was it photo-edited? I have no idea. I'd go for the former because it seems highly unlikely that a cat would take up this pose without human intervention and it sure looks odd. Hairless cats are prime candidates for odd but interesting photos. Of course, this hairless cat is entirely nude. So, it is rude if I say it looks like a film starlet. This adds to the strangeness of the image.

Lucy the 'bat cat' nude kitten with hydrocephalus

Lucy is described by her owner as "the bat cat". Not a particularly flattering title I have to say. You might know me and that I dislike these sorts of Instagram accounts because you get owners of strange cats vicariously achieving some fame for themselves through their cat. 

Often these cats are misshapen through a genetic defect or in this instance this hairless cat suffers from hydrocephalus which is a buildup of fluid on the brain which puts pressure on the brain and which can damage it. It is treatable and for humans and the survival rate for treated hydrocephalus is high. 

Lucy the bat cat. Photo: Instagram

Sorry if I upset some people in disliking these sorts of social media accounts. The pics are from Lucy's Instagram page. They were taken by her owners.

Lucy is called 'the bat cat' because of the obvious reason: she looks a little bit like one of those strange bats. And the stranger the cat looks the better for the celebrity cats.

My research indicates that a cat suffering from hydrocephalus may be asymptomatic. Alternatively, the symptoms might include, wetting or soiling in the house, sleeplessness, blindness, seizures, excess globalisation, hyper-excitability, a large dome-shaped head which is due to intracranial swelling, walking abnormalities, cross-eyes, abnormal breathing, arching their head back and extending all four legs and coma.

There are various causes including, inherited (congenital), genetics, prenatal infection, vitamin A deficiency, intracranial inflammatory diseases, masses in the cranium, brain haemorrhage in newborn after a difficult labour, exposure to teratogens (these are drugs which interfere with the development), coronavirus. We don't know which cause is applicable for Lucy. My guess is that it was inherited.

Credits as per above.

Lucy is a Sphynx cat by the way. She has 35,400 followers on her Instagram page. Her birthday is on March 15. She was born on March 15, 2019.

Are all cats wrinkly like hairless cats but we just can’t see it?

No, normal cats do not have wrinkly skin like the hairless cat breeds. Do breeders of hairless cats deliberately make their skin wrinkly? Hairless cats such as the Sphynx have incredibly wrinkly skin. Take a look at the cat below, bred in Moscow, Russia. It is like the skin of a 99-year-old man (worse!). Cats with coats do not have skin like this. What is going on? If you part the fur on a normal cat, you see whitish, smooth skin.

Are breeders creating skin wrinkles on hairless cats deliberately. Photo and breeding by Cattery Murmetroll, Moscow, Russia. This might be a Don Sphynx, Russia's version of the Spkynx.

I have asked a couple of Russian hairless cat breeders using FB messenger why their cats' skin was so wrinkled but no response. Maybe they are embarrassed. Perhaps they feel that they have been found out?

SEE SOME PAGES ON 'HAIRLESS CATS'

No one has discussed this properly but it needs to be explained. Perhaps the gene that makes these cats hairless also affects the elasticity of the skin. Or perhaps the skin has to be washed so much that it is damaged and becomes wrinkled. 

You probably know that the hairless cats become dirty because the oils from the sebaceous glands which are meant to go into the coat to make it glossy is deposited on the skin, as it has nowhere else to go, and it attracts the dirt. Yep, it is one of those troublesome little details that a hairless cat owner has to contend with.

My favourite reason why Sphynx and Elf cats have wrinkled skin is because the breeders selectively breed them like that. The breeders like the wrinkles as it gives the cat 'texture' and makes them look more interesting. Fair enough.

I have just checked the reddit.com website where they discussed this issue but no answer. They don't know. And that was 2 years ago.

Comments welcome please. We need to get to the bottom of this :) .

Hairless cat from the oil fields of Siberia

This is a striking hairless cat from: Noyabrsk City, Russia, the largest city in Yamalo-Nenets Autonomous Okrug, Russia; located in the middle of the West Siberian oil fields, on the Tyumen-Novy Urengoy railway about 300 km north of Surgut. He/she looks like a Sphynx but she might be a Don Sphynx (the Russian Sphynx) or a hairless dwarf cat without dwarfism! Let's just say she is a hairless cat from Siberia and she caught my eye. She/he was bred by Любовь Козаченко, who also took the photo. It is a fairly unsophisticated photo but noticeable for the cat's wrinkled skin. Why do hairless cats have wrinkled skin?

See above for details and credit.

Are hairless cats really hairless?

No, so-called "hairless cats" are not truly hairless because various parts of their bodies maybe nude but the remainder e.g. the muzzle and the feet (often) are covered by fine down, fuzzy hair. Sometimes hairlessness progresses with age. There is a fine covering in the young adult cat which gradually disappears leaving a bare, wrinkled skin over much of the body of the full-grown adults.

Bicolor Sphynx. The fine down hair strands in the hind legs are
pigmented I believe, which is why there is a dark patch and the tail
 is dark too. This is melanin in the down hair strands.

There is a bit of discussion about whether hairless cats can have a pattern on their skin. You do see 'bicolour' Sphynx cats with the two colours being the skin colour and the other colour being an inky darker colour. 

I had thought that the darker coloration was due to the pigment producing cells, the melanocytes, colouring the skin but I now believe that this is due to fine down hairs having the coloration that the cat's genetics gives it. The melanin in the hair strands being produced by the melanocytes.

To be clear, if you see a bicolour Sphynx or any other hairless cat what you are seeing is hair strand coloration. The point is that you can barely see the hairs because they are very fine and short, being the down or undercoat.

Hairless Devon Rex

A reminder that the curly haired Devon Rex can be hairless or partially hairless. I think the hairlessness can be permanent or transient. Perhaps someone can clarify that?

The point I am making is that if a Devon Rex is hairless the cat becomes something like a Sphynx cat. They have a similar appearance anyway. On that basis why not adopt a Sphynx instead? I think it just creates a complication. After all the main reason why people adopt a rex breed of cat is for the unusual curly coat. If that is missing, your not getting what you wanted.

Here is a picture of a hairless Devon Rex advertised for sale (at 1st Nov. 2011):

Cat Coats Hairless

Cat Coats Hairless looks like an illogical statement as there is meant to be no coat but as you might know, even in hairless cats, there is a coat (of sorts). 

Sphynx cats can have oily skin which smells unless bathed regularly. Picture in public domain.

Often there is a downy coat particularly in kittens and on the muzzle, nose, tip of tail, for example. 

The gene that produces a hairless cat is not confined to the Sphynx cats. I'm talking of the Sphynx (Canadian) and the Don Sphynx (Russian). 

It is possible to think that these are the only hairless cats, which as stated is not the case. The Donsky is more hairless apparently than the Sphynx, perhaps due to the dominant gene producing hairlessness in the Donsky allowing for more efficient breeding. 

Another notable hairless or semi-hairless cat is the Peterbald an associate or relative of the Don Sphynx (same founding cat). This cat breed was created in 1993 (a cross between the Don Sphynx and Oriental/Siamese). 

There have been numerous occurrences of the manifestation of the phenotype (physical attributes) of the mutant gene over the years as it pops up here and there. There is a link with the Rex coat as well. 

The Rex coat is crinkly and curly. Some Don Sphynx kittens have a Rex coat until adulthood. The Don Sphynx whiskers are often crinkly and brittle to the point where they snap off. 

The Rex coat is found on cats such as the Laperm and Devon Rex. The Devon Rexes are prone to baldness (hairlessness) so you can see link between these genetic traits. Sarah Hartwell records the occurrences of hairless cats on her website. 

Here are some recorded instances: 

- Latin America 1830

- Paraguay "Scant-haired cat" 1902

- Mexican Hairless (Mexico) 1932 

- Le Chat Nu (the naked cat) 

- France 1930s? 

- "Cat-Dog", Carolina, USA 1950 

- Paris France - two hairless cats born to Siamese cat 1963 

- Toronto, Canada 1978 

- Toronto, Canada - hairless street kittens 1978

- England - hairless Birman kittens 1981, 1984 

- England - reports of hairless kittens 2002 

- Hawaii - Hawaiin Hairless 

There are other examples and there will be more no doubt in the future, occurring randomly of their own accord. 

The gene that produces the hairlessness is dominant for the Don Sphynx and recessive for the Sphynx. 

The gene for the Donsky (dominant) is labelled "Hp" and the gene for the recessive (Canadian) Sphynx is labelled "hr". 

There are apparently two other recessive genes producing hairlessness (there may be more) and these are the French "h" and the British "hd".
