Ginger toms are friendlier and more confident that other domestic cats

It is dangerous to generalise but I think that it is fair to say that the general consensus among cat aficionados and perhaps some experts is that ginger tom cats are or tend to be more confident and more friendly than your typical domestic cat of other coat types and colours. But the "evidence" is largely anecdotal. That means there's no hard scientific evidence behind this claim. Although if enough people say it then you could argue that that is good evidence derived from personal experience.

Ginger toms are friendlier and more confident that other domestic cats
Confident and friendly ginger tom cat at a supermarket.

RELATED: ginger cats are almost 18 times more predisposed to skin cancer than other domestic cats excluding white cats. Why? Find out my reason by clicking on the link below:


A BBC article quotes Roger Tabor a broadcaster and naturalist and an expert on cats. He said the following on this topic:
"To be a ginger cat, a female kitten has to inherit two copies of the ginger gene, but males only have to inherit one. Measurements have also shown that generally male ginger toms are heavier than most cats of other colours. Male ginger cats tend to be both taller and broader than most other moggies - apart from the North American Maine Coon."
It could be that if ginger tabby cats are a little larger than average this makes them more confident and therefore more fearless which improves the possibility that they might become "leaders" in a cat colony. It also might make them more outgoing. So there may be a scientific connection here.

From my perspective, I remember meeting a ginger tabby cat in Malta who was indeed a leader of a cat colony. A colony of cats rescued by the lady who owned the house where he lived. Her name was Martha Kane. She has passed over the rainbow bridge to meet her beloved rescue cats there but her website is still on the Internet and I refer to it out of respect for her.

On the Internet there are a lot of stories about ginger cats looking very confident and liking the attention they draw when in public places such as a ginger and white tabby called Nala who likes to sit on ticket scanning devices at a station in Stevenage in Hertfordshire. No doubt he likes the heat from the devices but he probably also likes to meet the people passing through the devices.

And there is a ginger and white tabby cat in a branch of Tesco in Norwich, beloved of the public, but the management are not quite so sure about his presence. He likes to sit on self-service checkout machines looking for a bit of attention. 

And in Ely, Cambridgeshire, another ginger tabby called Garfield became very popular in Sainsbury's. After his death a eulogy was held in the city's cathedral and a brass monument was erected in his memory.

Here are some other points provided by my assistant:

Ginger cats, also known as orange or marmalade cats, are indeed quite special! Their striking appearance and unique coloration make them stand out, but it’s their temperament that truly captivates cat lovers. Let’s explore why ginger cats are often described as friendly, sociable, and outgoing:

  • Friendly and Affectionate Nature: Ginger cats are known for their friendly and affectionate behaviour. They thrive on companionship and love engaging in playtime and interactions with their human counterparts. If you’re looking for a feline companion who enjoys cuddles and attention, a ginger cat might be a great choice!

  • Sociability: These cats tend to be more social than some other coat types. They often seek out human attention and enjoy being part of family activities. Their outgoing nature makes them wonderful companions for households with children or other pets.

  • Independence with a Dash of Charm: Beneath their sociable exterior, ginger cats also have a streak of independence. They strike a balance between seeking affection and having their own space. Their playful and curious personalities add to their charm, making them delightful pets.

Remember that individual personality and temperament can vary among cats, regardless of coat colour. While ginger cats generally exhibit these positive traits, there are always exceptions. If you’re considering adopting a ginger cat, spend time getting to know the specific cat’s personality to ensure a good match for your home and lifestyle! 😺🧡.

Why do domestic cats have thinner fur between the ear flaps and the eyes?

The Live Science website asks a similar question but I think the way I have asked the question is more accurate. They ask "why do cats have bald spots in front of their ears?" Well, firstly, these are not bald spots. The hair is thinner between the top of the eyes and the flaps. Secondly, although Live Science claim that small wild cats have the same anatomical characteristics, I don't think they do. On this page you will see a headshot of a serval which is a medium-sized wild cat compared with a headshot of a black domestic cat.

This is typical of the black domestic cat but there are variations:

Headshot of a black domestic cat showing thinning of the fur between eye and ear flaps.
Black domestic cat showing thinning hair from above the eyes to the base of the ear flap where skin is genuinely bald. The photograph is from Wikipedia and therefore published it under licence.

This is a serval:

Headshot of a serval showing no thinning of the between the eyes and flat
Serval headshot showing continuous fur above the eyes and up to the flaps. This photograph, it is believed, as in the public domain.

You will see that the serval's fur between the eyes and the that is pretty solid and it doesn't seem to be thinning to me. Another point worth making is this: every time we discuss this topic we invariably show an image of a black domestic cat. This is because there is greater contrast between the white skin underneath the black fur making the thinning coat more obvious.

Also the fur there tends to stand on end. It is vertical which makes the skin underneath more visible.

Another point worth making is this: I don't think all domestic cats have the same level of thinning fur at this point on their face. It varies which is understandable because domestic cats do very.

But it has to be said that often times we see this characteristic so what causes it? The frustrating answer is that we don't know. I think one reason is that the hair strands tend to sit more vertically at that point which makes the skin below easier to see which could add to the impression that there is partial bolding at that point.

Live Science suggests that the thinning fur at that point is to help with hearing because the sound waves bounce off the head between the eyes and ears before entering near ear canal and impinging upon the eardrum. So this thinning fur maybe to do with improving hearing. That's the best guess so far.

It might have nothing whatsoever to do with hearing, however. It might just be a domestic cat trait because of their domestication. Fur is present to keep the cat warm and to protect them. Arguably, both of these benefits are not strictly required by a well cared for domestic cat. Perhaps, then, it is an evolutionary trait during the 10,000 years of domestication. That is another big guess.

It may be nothing to do with evolution. It could be a problem with thinning coats generally due to their lifestyle and/or diet which might not be entirely appropriate but which is not clear to humans. Perhaps the domestic cat is losing fur and this process is not visible in most areas of the coat because the fur is denser elsewhere than in the area between the top of the eye and ear flaps.

So perhaps this so-called bald patch is a symptom of a generalised inadequate domestic cat caregiving and its variation is because in some homes caregiving a superior than in other homes. We need another study on this to do some tests to get to the bottom of it.

Are there age-related differences in cat coat colour?

Yes, there are age-related differences in cat coat colour and in fact markings. One comes to mind immediately which is you will see a young mountain lion cub with a spotted tabby coat while their parents are of one uniform colour. 

Image: MikeB

Nature has given the cub the added camouflage of the spotted coat because they are vulnerable particularly when the mother leaves the nest to hunt for food to bring back to her cubs. And at this time, when the mother is away, inquisitive cubs might venture from the nest making them more vulnerable. 

This difference between cubs and parents in terms of coat colour and markings is noted in the name of the mountain lion a.k.a. puma of which the Latin name is Puma concolor which means of an even colour.

In fact, all mammals exhibit important and obvious morphological (visible differences in anatomy) age-related differences. Humans are mammals and all of us realise that human hair changes as we get older. Hair colour lightens and becomes grey. The backs of male gorillas turn white at about the age of 12 which is why they are called silver-backs.


And we have to remember that elderly cats also develop grey hair around the muzzle as do dogs. It's quite a subtle change and its extent depends on the cat but it is sometimes quite noticeable.

And, turning to one of the popular cat breeds, the Siamese, when a new-born arrives into the world, they are pure white because they've been living in an even and warm ambient temperature, inside their mother's womb. 

But when they arrive into the world the kitten's extremities become colder than the central part of their bodies. This temperature gradient triggers the Siamese genetics which causes body extremities such as the distal parts of the limbs, tail, face and ears to become darker while the warmer the central areas remain lighter.

Interestingly, elderly Siamese cats have darker central areas because their cardiovascular system is less effective resulting in the dermis becoming cooler which means the central part of the body which is normally warmer starts to become cooler which means it becomes darker.

These are some examples of how age-related differences can be observed in cat coat colour and pattern.

This is a cross-post from another site.

What are 'laces' in the cat fancy?

Laces refers to white fur on the back feet. You'll see them on some cat breeds like the Birman and Snowshoe. The Birman is a pointed cat with 'gloves' (white fur on the feet to contrast with the dark pointing). These gloves on the hind feet are referred to as laces. In the Birman the laces finish with an inverted V extended half to three-fourths up the hock. The hock is at the end of the foot and the beginning of the leg; the joint between the tarsal bones and tibia of a digitigrade. The cat is a digitigrade (walks on their toes).

The cat fancy likes to use these terms that are applicable to human clothes. Another is 'britches' (or pantaloons) which describes the longer fur at the top of the hind legs of some cat breeds.

Cat coats: solid-and-white - bicolor cats

black and white cat
Cat Coats Solid and White - Bicolor - photo copyright fofurasfelinas


This is another posting on cat coats. This time I discuss the impact of the white spotting gene on "solid" colored cats other than Tuxedo cats, which I have already discussed on this page. Tuxedo cats are very common and specific in their coat pattern so I've dealt with them separately. Both are bicolor cats meaning a cat coat of two colours, white and another solid colour.

Bicolour development - white spotting gene. Image: Sarah Hartwell.

The particular effect that the white spotting gene has on any one cat dictates the spread of white fur on the cat (or put it another way it restricts the spread of color). The cat fancy has given names to the patterns caused by this gene, which by the way is also called the piebald gene. It is considered a "semi-dominant" gene.

Bicolour faces white spotting gene. Image in public domain.

White spotted cats are one of the most common cats. The white spotting gene (represented by the letter "S" in the science of genetics) can change the appearance of any colored cat including tabby cats or tortoiseshell cats or a combination of the two (torbie). [See cat coats tortie and white]. When it affects a tortoiseshell cat, the cat is called a calico cat in the States.

Bicolours. The chart is by Sarah Hartwell of messybeast. Many thanks.

RELATED PAGE: White spotting gene charts.

A fine example of a cat with a solid and white coat is the Turkish Van (high grade spotting - see below). This has, of course, the "Van" pattern. Van is a town in the South east of Turkey, where the Turkish Van originally came from (including adjacent regions).

Another example of a well-known cat breed with a "solid and white coat" is the Japanese Bobtail. The Japanese Bobtail has a Bicolor pattern in both "solid and white" and calico (which is tortoiseshell and white mentioned above).

I discuss, in brief, the workings of the piebald gene on the Tuxedo cat page as well as here. The effects of the piebald gene can be seen to varying degrees. The amount of white dictates whether the pattern is a grade 9 (almost total white with the colored fur limited to a few spots). This is called high grade spotting.

At the other end of the spectrum at grade 1 there is a very small amount of white. This is called low grade spotting. When the cat is low grade the genotype (genetic makeup in relation to the cat's coat) is normally heterozygous represented by the letters "Ss". Conversely when the coat is high grade (lots of white) a spotted cat is generally homozygous "SS".

The presence of the piebald gene results in white fur by causing special embryonic cells to behave in a defective manner. These cells are called "Melanoblasts" and they become the cells of the cats body that produce the granules of pigmentation that are embedded in the individual hairs. During the embryonic stage these cells migrate from the spine area. They fail to migrate properly and fully causing parts of the body to be without color. The wide variability of the effect of this gene is due, at least in part, to the presence of other unidentified genes called "polygenes".

The great Dr. Desmond Morris discusses bi-colour cats in his book Cat World. He tells us that such patterns are most common in non-pedigree cats. But of course, you will see this coat type in pedigree cats as well. It depends on the breed standard is to whether they are allowed or not. In the early days of the cat fancy the bi-colour cat was less likely to be accepted because they felt that they made a pure-bred animal look like a moggy.

This was prejudice against the coat but it was more likely to be accepted if there was some sort of distinguishing factors about the bicolour coat such as an attractive symmetry or the distribution of the colour was interesting.

In the early days of the cat fancy the black-and-white coat was referred to as a 'magpie cat'. And sometimes the bicolour cat is called a parti-colored cat. You will see "parti-colored" spelled in different ways. Apparently bicolour cats only attained championship status within the show cat fraternity in 1966.

You will see bicolour cats in longhaired and shorthaired cats and in many cat breeds such as the American Shorthair, British Shorthair, Devon Rex, Cornish Rex, Japanese bobtail, Maine Coon, Manx and Persians. These are just examples. There are others.

Here are some photographs of the solid and white coat pattern:

Introduction - history


The tabby markings/color
is probably the most common, in either domestic cats or wild cats (e.g. Scottish wildcat). When cats breed randomly over a long period of time, apparently the coat color and pattern tend towards brown mackerel tabbies with green eyes (the most common "phenotype" - meaning the observed expression of the genetic make-up).

RELATED: Why are tabby cats so common?

This indicates a genetic predisposition towards what is probably the most efficient coat color/pattern in respect of the cat's survival. There are three tabby patterns: the classic blotched pattern, the striped or mackerel pattern, and the spotted pattern. The Bengal cat for example can have a spotted tabby or blotched coat, while the Egyptian Mau has a naturally occurring spotted tabby coat - the only naturally occurring spotted domestic cat it is said. 

The agouti ticked coat (the Abyssinian cat has the classic ticked coat) is a special kind of tabby coat. 

The Abyssinian has a special tabby coat. There are few markings unlike the usual tabby coats that can be spotted or blotched. This picture shows the banded hair strands. This photo is published under a Wikimedia Commons license. Author: Martin Bahmann 


As mentioned, you can see the tabby coat in wild cats such as the African wildcat and American Bobcat for example. However, I don't recall seeing a wild cat with what the cat fancy calls the "blotched" tabby coat. All wildcats appear to have spots and/or stripes or no tabby pattern. The blotched tabby appears to be a creation of the cat fancy or at least it has been "developed" and enhanced by the cat fancy (cat breeders).

Dr. Desmond Morris, the great zoologist and writer, tells us that it is believed that blotched tabbies arose first in Britain in the Elizabethan era. As you can see, they arrived very late during the evolution of the domestic cat. For the first 2,000 years or so or more all tabby cats were spotted/striped (broken stripes) tabbies and all domestic cats were spotted tabbies. And therefore, all domestic cat during the era of the ancient Egyptians were spotted/striped tabbies.

Dr. Morris says that the blotched tabby became a winner. In other words, a favourite and he is not sure why they did so well. Perhaps they were more healthy or more fertile than the other forms of tabby cat or perhaps they had an unusual level of aggressiveness or assertiveness. Perhaps people just like them and informally bread them?


Development of the blotched tabby domestic cat. My thanks to the scientists of the study:  The palaeogenetics of cat dispersal in the ancient world.


Today, the blotched tabby is the most common form of tabby coat and the striped tabby has gone into somewhat of a decline. Of course, nowadays the tabby coat is just one of many types of coat that have evolved during domestic cat evolution. However, Dr. Morris reminds us that genetically and in reality all domestic cats are tabbies. If they don't appear to be tabbies it is because the tabby pattern is masked by the other non-tabby colours.

Of course, the tabby pattern comes from the original domesticated wildcats. The North African wildcat has a week tabby pattern. And if we want to visualise the early domestic cats all you have to do is look at today's African wildcats. From paintings created in ancient Egypt we see that the Egyptian cats had light or broken stripes. When they were exported over thousands of years to other parts of the world including Europe, the cats began to hybridise with their European counterparts and the result was a full-tabby coat.

Tests have shown that when the week-tabby European and African wild cats were experimentally crossed the hybrid kittens developed coat patterns which were much closer to the full-tabby pattern of modern domestic cats according to Dr. Desmond Morris. I have quoted him verbatim.

All tabby cats have the classic M marking on the forehead in varies styles and disguises.

An example of a purebred and pedigree tabby cat would be the American Shorthair.  This breed looks particularly stunning in silver tabby. Another example of a beautiful purebred Maine Coon tabby can be seen by clicking on this link. The tabby pattern is often seen in Maine Coon cats. The cat associations allow a wide range of Maine Coon cat coat types (you'll see a great tabby MC on this link). There are some classic tabby patterns on wild cats. A good example is the tabby coat of the wildcats. These cats look very much like domestic cats as they are the wild ancestor of today's domestic cat.

Origin of Name

It is thought that the word, "tabby" originates in the appearance of silk sold in Baghdad (the Attabiyah region). This region must have been known for selling silks that had a striped appearance (watered - waved - silk) as incorporated into the name. Attabiyah is reference to the Latin attabi, and later the French tabis, which means, as I understand it, watered silk. As the striped and marbled tabby cats have the same general appearance, the word "tabby" was used to describe the coat.

The Genes

As mentioned, the wild cats have tabby coloration and patterns and the domestic cat is descended from the wild cat (see a comparison between the Scottish wildcat and domestic tabby). The pattern has 2 elements to it. (1) There will be a group of hairs in which the individual hairs have bands of color running horizontally up the hair strand. One band will be yellow and the next black. These hairs form the background color upon which the pattern is overlayed by the second group of hairs. The commonly spoken of "Agouti" gene (A) creates this banding pattern on the hair shafts. The banding on the hair shaft is due it is thought to a reduction in the production of the pigmentation granules or the production of a different and yellow pigment. This results in fewer granules that are spread more thinly throughout the hair follicle to give the beige/yellow looking color.

The pigment producing the black band in the hair shaft is called eumelanin and the yellow pigment is called phaeomelanin.

Tabby Hair Strand. Image: MikeB.


If the band near the surface is beige you get the light brown broken effect and if the black banding is near the top the black is broken up by the beige banding lower down. (2) The other group of hairs will be black because the yellow banding referred to above will have been reduced (repressed) to the base of each hair or removed entirely. This group is seen as the spots or stripes or blotchy patches of black or brown that forms the patterns seen in the pictures. This effect is a result of the presence of the Tabby gene (Mc/mc), which is present in all cats and so are the markings but often sufficiently suppressed as to be invisible.

I know a small classic tabby that has also solid black hair in swathes, and also black hair with one band of beige near the surface which creates a speckled look on black. All these combinations are mixed together in various proportions and in varying sized clumps to produce the tabby pattern. The pattern that we readily see is due to the alternation of solid color (black fur) with the banded fur to create a pattern as mentioned above. It is the Primary Tabby gene (Mc) that dictates how the pattern will shape up for the individual cat.

There are several varieties of tabby markings and of course as mentioned an almost inexhaustible spectrum of colors, contrasts and pattern variations particularly in purebred cats where the appearance of the cat is of paramount importance.

The type we probably are most familiar with is the mackerel, stripped tabby. This is considered the wild type of tabby pattern. The genotype (the genes producing the black tabby coat) is A (agouti) + B (black) + D (dense coloration) + Mc (tabby gene).

Breeders like high contrast striping that is nice and evenly spaced and the stripe should be continuous. The Toyger has this. The Toyger also has a beautiful base or ground color that is incredibly warm (orange almost). The base color comes from the color of the agouti band on the individual hair strand. The warming up of the ground color is due to selective breeding in modifier genes (rufus modifiers).

Silver classic tabby cat - This as you might have guessed is an American Shorthair cat. I have a post dedicated to the American Shorthair tabby cat. The silver is due to the Inhibitor gene I, which inhibits the production the yellow Agouti banding leaving the black to contrast more starkly with a gray/silver background.

The genotype (the genes producing the black tabby coat) of the classic blotched tabby cat is A (agouti) + B (black) + D (dense coloration) + mcmc (tabby gene). The difference to the mackerel tabby is the existence of the mc allele (allele = one of a pair of genes).

Spotted Tabby

Research is still being carried out on the genetics behind the spotted tabby coat. It may be due to a modifier gene on the mackerel tabby. The striping of the mackerel tabby can break up and if that is captured and bred into the cat you'll get spots. In the Ocicat it seems that the effect is due to a dominant modifier of the blotched classic tabby pattern.

Robinson's genetics says that the gene that produces the Abyssinian ticked coat is not the same gene as the tabby gene producing the classic and mackerel. They call it the "ticked gene". The authors say that the Abyssinian cat's appearance is a mutation of the normal tabby. The tabby pattern occurs on the head, legs and tail and very faintly elsewhere on the body. Breeders like to reduce the pattern further by careful breeding. The most frequently seen Aby color is the ruddy (red) - middle picture above - called the "usual". Breeders breed in a warmer color.

The full set of genes producing the well known Abyssinian coat are: AA (Agouti) - B (black) - D (dense coloration) - TaTa (ticked gene).

The tabby cat locus maps to the feline chromosome B1. It seems possible that the tabby gene has a homologue (common evolutionary origin) on human chromosome 8 or 4. (src: http://www.pubmedcentral.nih.gov/)

Interesting

This is an interesting bit of information about the tabby cat as camouflage, which comes from Desmond Morris's book "Catwatching". It had been proposed by a nineteenth century naturalist (I presume) that when a tabby cat is curled up she/he looks a bit like a "coiled snake". Once again this is a form of mimicry, one of a number of examples of the cats mimicry of the snake as an act defensive. Read about a cat hiss as another example.

A Torbie is a mixture of tabby and tortoiseshell. An example of tortoiseshell is the black tortoiseshell or just plain old tortoiseshell cats (this page has great pictures). Some people think the tabby cat is a cat breed.

Behavior of a calico cat. Do they have a specific personality?

The behavior of a calico cat is no different to that of other cats. In other words, the genes that give this cat her calico coat do not affect her character. That, in any event, is my considered view. I guess we all know that a calico cat is not a breed of cat but a description of the coat color. My view may be incorrect 😉 - see below.

Calico cat and her offspring
Calico cat and her offspring. Photo in public domain.

"Calico" is a North American term. In the UK the calico cat is called "Tortoiseshell-and-white". As the UK name suggests the coat is a mixture of tortoiseshell fur (black and orange) and white. The white is caused by the white spotting gene or piebald gene. This gene causes the mitted or gloved cats (Snowshoe and some Ragdolls) and the van cats (Turkish Van).

 We also know that due to genetics, calico cats are virtually always female. This is because the gene that determines red (orange) coloration is carried on the X chromosome and a cat has to be XX (female) for the orange gene to take effect (I think that's correct - tell me if I am wrong, please).

Japanese people like the calico color. This is shown in their love of bicolor and calico Japanese Bobtail cats. They call this color pattern mike-cats or 'tricolour' cats.

The genetics at work are all concerned with the coat color. As far as I can see there is no further effect (beyond coat color) that determines the character of the cat. I conclude that calico cats have no specific character associated with the coat color. 

However, I may be wrong because Dr Bradshaw says that there may be a link between coat type/colour and personality in pedigree cats due to selective breeding. Breeders may create this link by choosing foundation cats which have a nice character plus the desired coat. It is an artificial connection in purebred cats due to human intervention.

RELATED: Ginger Cat Personality.

The association between the color of the fur and character of the cat is similar to our perception that red-headed people (and particularly females) have a specific and associated character e.g., fiery and volatile. This is due to their "difference" (in the way they look). People tend to be frightened of different people and attack them. 

In the same vein the calico and tortoiseshell cats are considered to have 'catitude'. We tend to stereo cats according to their coat type and colour. Sounds familiar?

They do this by making slightly derogatory remarks (this is my theory, anyway). It is untrue that red-headed people are generally fiery. If they are sometimes like that, perhaps they are being irritated by being thought of as being fiery by other people! I can't find evidence on the internet which scientifically links red hair with a specific personality traits. Wrong? Please tell me in a comment.

One point though does come to mind about the behavior of a calico cat. We know that females of the species act differently to the male. As calico cats are nearly always female it could be argued that their behavior is different to the average. Just a thought. 

 There is a tendency then for humans to assign a character to an appearance. This is the same for people's perception of cats generally. Some people hate cats because they think they "sneer" at them when it is in fact the person's own prejudice coloring the perception. The same distorted perception is found with black cats. They were thought of as witch's cats and there are still numerous superstitions surrounding black cats (good luck, bad luck you name it).

A cat coat to protect against the worst winter weather

When I first laid my eyes on this picture of a beautiful long haired cat I thought of a pigeon! You know how pigeons sit on their perches with their feathers fluffed up in order to trap warm air below them; well, this cat looks a bit like a pigeon with fluffed up feathers.

And I've not seen a domestic cat with a coat so suited to deal with cold weather than this brown tabby who appears to be sitting on a roof terrace of a block of apartments. That's a guess but it is a reasonable guess or it is a patio of some sort. 

My guess, too, is that this is a purebred cat. Well-bred pedigree cats have a look about them and this cat has that look. I'm guessing a Siberian but you just can't tell by appearance. That said, you don't see this kind of density and length of coat in any other domestic cat other than a Siberian purebred cat. This, of course, is to be expected because Siberia is so damned cold. Although it has been warming up of late with global warming where temperatures have reached 30°C and all the permafrost is melting! That's why they dug up some cave lion cubs recently in Siberia which had been in the permafrost for, I can't remember, about 30,000 years.

He or she may be a Maine Coon but the overall look of this cat does not point to Maine Coon in my honest opinion. Too cobby.

But within each breed there is quite a wide variation in appearances of individual cats some of whom are not bred to type as they say in the cat fancy.

In terms of maintenance by a cat's caregiver, it perhaps goes without saying that the single, silky coat of cats like the Siamese is far easier to manage. But evolution has equipped cats such as the one on this page and, for example, the Norwegian Forest Cat and the British Shorthair with winter busting protection. They have dense coats with insulating down hairs next to the skin.

In cold weather the hair stands erect trapping a layer of air like double glazing while a thin layer of fat under the skin insulates the body. When a cat wears a single coat they radiate more heat from their bodies which helps to keep them cool. 

Of course, the Siamese comes from Thailand formally Siam which is relatively hot compared to the state of Maine in the USA. Siamese cats lack down hair and cats that have this insulating coat shed it in hot climates.

Is cat personality linked to coat colour and type?

People like to think that there is a connection between the appearance of someone or an animal and their personality. British people refer to tortoiseshell cats as being "naughty torties" or having "catitude". Sometimes blotched tabbies are referred to as "real homebodies". And mackerel tabbies are seen as being independent. While white patches on a cat's coat have a calming effect on the personality.

Incidentally, it is not until fairly recently that people started to understand that domestic cats have a personality. Even scientists believed that only humans had personalities. That seems hard to believe nowadays.

I've always felt that red tabby cats have good relaxed characters. Red tabbies are also called ginger or marmalade cats. They always seem to be spoken of in glowing terms as companions with nice, affable characters. But this is all anecdotal. To turn to science, some scientists believe that the biochemistry that creates different coat colours and types also affects the cat's brain. This is called "pleiotropy". But apparently there is little evidence to support this scientific theory says Dr Bradshaw in Cat Sense.

Perhaps we are on a more solid scientific footing when we turn our attention to the purebred, pedigree cats. With pedigree cats there is a lineage so we know the parents and grandparents; in short, there is a family tree, which allows scientists to study the inheritance of the genes.

There is a relatively restricted gene pool in breeding lines which allows the temperament of a founding cat to be brought forward all the way down the breeding line. So, for example, there is a limited number of high-quality male cats within each breed who are available to produce the type of coat desired as per the breed standard. As a result, the personality of these tomcats becomes predominant within a section of all the cats in a single breed.

For example, there was a time about 20 years ago when British Shorthair cats bred in Scotland with tortoiseshell, cream and especially red coats were difficult to handle. They traced this personality trait back to a single male cat who had a difficult personality. This, incidentally, is an example of breeders breeding for appearance over personality. This founding, male cat was unsuitable, it seems.

And also pointed cats, which you will see both in the Siamese and other pedigree cats and indeed in non-pedigree cats, are likely to be vocal. This is a well-known trait for Siamese cats. The reason, it is said, is because the gene that causes the points i.e. the dark extremities to the cat's body are rare unless that cat has at least one Siamese in its recent ancestral past.

Another way in which coat type and colour can be linked to personality is when the gene that controls the coat is physically close, on the same chromosome, as the gene that affects the way the brain develops. Under these circumstances the chances that a kitten will inherit the combination of these two genes, one affecting the coat and one affecting the brain is much higher. They tend to be inherited together although it doesn't always happen.

An example would be the dominant white gene which causes a cat's coat to be devoid of pigment and therefore is white, sits next to a gene which causes both eyes to be blue and the cat to be deaf. That's why white cats are often deaf with blue eyes or they have odd-eye colour. Because the cat is deaf it affects their personality and therefore in this instance coat type and colour affects personality.

I am indebted to Dr John Bradshaw for the above. Some more...

One aspect of people attaching personality to coat type is that it may colour their opinion of their cat (excuse the pun). The point that I am getting at is that if a person believes that tortoiseshell cats are naughty and if with that belief, they mishandle their tortoiseshell cat and are scratched, the two aspects to their relationship come together which may result in the cat being relinquished to a shelter.

A study found that participants were likely to attribute friendliness to orange cats and intolerance to tricolour cats and aloofness to white and tricolour cats. White cats were seen as being more shy and calmer than cats of other colours.

The participants to the study said that they thought personality was more important than colour when selecting a cat companion. This is interesting because cat breeders of purebred cats attach more importance to appearance that personality. There appears to be a disconnect between cat breeders and their clients.

AITA for adopting a cat that has a penis on his face and naming him Richard?

AITA is an acronym Am I the Asshole and in this instance a man posted the title to this page on the reddit.com website. He tells the world on that high hitting website that he adopted a rescue cat who had been left on the shelf. Nobody wanted to adopt this cat because of the markings on his face and those markings look a little bit like an erect penis.

The fact that he adopted the cat was a good thing, but he called him Richard knowing full well that he would call him Dick for short. He then asked all the visitors to his reddit.com post whether he was an asshole in doing what he did.

It is interesting to note that the administrators of reddit.com have removed the picture but the headline is still there. The picture is above. Well, I have given this some consideration and I think he has been an asshole. I think he adopted the cat because he wanted to make him a celebrity and in doing so, he could become a minor celebrity himself. He wanted to live vicariously through his cat. A lot of people do that on the Internet; they achieve what I would call 'vicarious celebrity status' through their interesting-looking domestic cat companion.

The first problem is that he rescued the cat for the wrong reasons, in my opinion, but I am speculating and therefore it is not fact. Secondly, he did not have to ask the question on a social media website and he did not have to name him Richard. 

So, he did quite a lot of things which he shouldn't have done and in doing these things he disrespected his cat. He did not insult his cat for obvious reasons, namely that his cat did not know what was going on but that really isn't the point. If a cat owner disrespects their cat, he is doing the opposite to what he should be doing which is respecting the cat because out of respect flows excellent cat caretaking.

I would conclude that he is not ideal cat owner. A really good cat owner would not have done what he has done. Those three errors in judgement, as I would call them, would not have been made. Or if a good cat owner had adopted this cat because he was left on the shelf, they would have simply left it at that and loved him and cared for him without publicising his picture on the Internet and giving him an inappropriate name.

Picture of a cat with a triple heart pattern when sitting

The title says it all. A heart pattern on a domestic cat is not very unusual. But when there are three heart patterns, one on the face, a second on the chest and a third formed by the forelegs, it has to be said to be highly unusual. It certainly caught my eye which is why I decided to republish it on this website. I don't know who took the photograph but I am confident that it is in the public domain because it must've circulated around the Internet and in doing so any copyright would have been lost in my humble opinion.

I don't believe that this cat is purebred but she/he might be a bicolor (2 colours) British Shorthair. I think that is the only cat breed which is possible. The cat is more likely to be a rare random bred cat. They do occur.
