Why do kittens change eye color and when does it happen?

Among hundreds of varieties of domestic cats, cat breeds with green eyes are especially popular.
Independent and affectionate, smooth-haired and fluffy, large and miniature breeds are being improved, delighting breeders and bringing happiness to the lucky owners of purrs. In February 2022, the international club of cat lovers “Cat Fancier's Association” took into account 42 new breeds that were bred in different countries. How to find green eyes among all the diversity of the cat kingdom?

Gray cat with green eyes: breed and photo

The green color of the eyes harmonizes perfectly with the smoky gray coat, which was given a more aristocratic name among breeders and felinologists, and the gray color turned into “blue”. It is not at all surprising that the combination of blue fur and magical green eyes became the reason for the formation of several magnificent breeds.

Russian blue

It’s nice that this breed of cat with green eyes has retained Russian roots in its name, although it is not known for certain whether it originates in Russia. These elegant and aristocratic cats with a slender, graceful body, plush fur coat and delicate, gentle character charm people the first time they meet them.

The coat of Russian Blue cats is quite short, thick and dense, evenly colored and has a pleasant pearl-silver tint. Almond-shaped eyes are a bright emerald color as standard; other eye colors are not allowed. We wrote more about the Russian Blue breed in this article.

Nibelung

It is very rare to find cats and cats with green eyes of the Nibelung breed. This beautiful name means “fog” in German. The Nibelungen is a long-haired version of the Russian Blue cat, and they do have a lot in common, such as emerald green eyes and blue fur with silver tipping - the very tip of each hair is bleached, which gives the coat a beautiful silver shimmer.

Black color allowed

If the previous breed is called the Bombay Black, then among the short-tailed American females there may also be black individuals. This fluffy dog ​​is susceptible to training and has high intelligence. If your pet is accustomed to wearing a harness, he will be happy to take walks with his owner in the park.

The color includes various shades of black and tabby - black stripes on a fawn or gray background.

Siberian cat

These majestic creatures are covered with thick hair with a water-repellent effect, have a double and dense undercoat and “pants” on the hind legs. They are excellent hunters of mice and rats. They are easy to care for and tolerate almost any weather conditions well.

Oriental cat

The elegant blue-black cat with charcoal pads is the most “refined” among its relatives. There are a total of 42 types of colors in individuals of this breed. Affectionate and friendly pets are not pretentious, but they should be protected from the cold.

Devon Rex

Large shining eyes combined with “elven” ears are mesmerizing. The neck is thin and the head is slightly flattened. The beauty walks on high legs and proudly wears her long tail. The animal is energetic and affectionate, and is also well adapted to life in the city.

Turkish Angora

The long-haired cutie was brought from Byzantium. Fluffies can be painted in different colors, including pure black, with white splashes and other options.

Norwegian forest

The fur of representatives of this breed is smooth and thick. Sideburns can be seen on the cheekbones. In winter, a fluffy chic collar “falls” over the shoulders and neck. The ears are pointed with tassels, the tail is long, the legs are high with heavy pads. The color is varied, but always the same color.

American Curl

The small cat has hard ears that turn outward. The animal's character is spontaneous.

The Curl is the first cat breed in which the standard allows short-haired and long-haired varieties.

These cats have come into fashion in Russia relatively recently. At the moment, Maine Coons are extremely popular in our country. The main features of this breed are its truly gigantic size (weight up to 13 kg), the presence of a large “hooligan” box (the place where the mustache grows) and fluffy, rather long fur.

Cats are really big and often even look scary. However, the temperament of representatives of this breed is actually very soft and flexible. Despite their somewhat “street” appearance, the animals are exclusively indoor animals. Maine Coons have retained their hunting instinct. That is, they can catch mice and birds, for example, with the same zeal as other cats.

However, Maine Coons, unfortunately, cannot stand up for themselves on the street at all. Representatives of this breed have great love for all living creatures, including neighbor cats or even dogs. Such an animal can approach a pack of wild dogs completely without fear, which, of course, will end badly for him.

Blue-black wool for Maine Coons is considered one of the standards. Often such cats also have emerald irises. A photo of a black Maine Coon cat with green eyes can be seen below.

The rich green color of the iris is characteristic of the black solid color, along with yellow and copper, but a black cat with green eyes cannot be of any breed. For example, black Persians, exotics, Britons, and Scottish Folds have only orange or yellow eyes.

Green ones are allowed in cats of oriental and aboriginal breeds. It is interesting that there is a breed in which black solid color is the breed-forming one - this is the Bombay cat, although according to the standard it is supposed to have yellow, amber or golden-colored eyes, and green will be a disadvantage. Let's look at the breeds of black cats with green eyes.

A Maine Coon cat of a solid black color with green eyes evokes awe - the strong, powerful bones of these cats, their large lynx ears with tassels and the often stern expression of their faces immediately make it clear who is boss in the house, although their character is quite peaceful and flexible .

The breed standard allows all shades of green iris, the main thing is that the eye color is in harmony with the color and is as pure and bright as possible.

Which cat breeds have specific eye colors?

The color of the iris, like the color of the coat, certain characteristics of the breed (fur length, weight, body shape, etc.) are inherited. Different breeds have their own characteristics, including the shade of the iris. Certain colors are included in the list of characteristics approved by international standards, and if a kitten is born with an atypical eye color, it may be disqualified. What representatives of the cat family look like with different eye shades can be seen in the photo below.

Professional superstitions

There are a number of signs that exist within the framework of a particular professional activity. This could not have happened without the participation of a black cat.

Remember, you can find black cats in shelters and rescues throughout the county. In fact, rescuers end up with more black cats than any other type of cat. Unfortunately, they are also the last to find homes, according to the Animal Legal Fund.

Rebecca Desfosses is a freelance writer specializing in parenting and family issues. Cats, like other mobs, can breed with other members of the same species. All you have to do is have two tamed cats and make sure they get up. Take two raw fish and feed them one at a time. They will have love hearts over their heads and they will run to each other and have a little chat. Then a small kitten should appear, the pattern of which will match one of the parents.

For example, theater actors have a superstition that if a black cat rubs against the director’s legs before the premiere, then the play will be a great success. In general, the presence of such an animal in the theater is good luck, only if it does not end up on stage. Especially if a cat appears out of nowhere and crosses the stage diagonally, this means failure. But even in this case, you cannot beat the animal - you can try to lure it behind the scenes and be sure to feed it tasty.

Cats can breed once every five minutes, but kittens cannot breed. To tame Ocelots so they can become your Cat, you must feed them 2-5 fish. However, since this is a shy crowd, you will need to stand still. Eventually, Ocelot will slowly approach you, and at some point he will stop and just look at you. Do not make any sudden movements such as moving your head or walking, as the Ocelot will become afraid and run away.

Cats love to sit on chests, beds and active stoves, reflecting the behavior of real cats. While active furnaces are not affected by sitting cats, chests and beds. If a cat is sitting on a chest, it cannot be opened, and if one is sitting on a bed, the player will not be able to sleep. The only ways to stop them from sitting on a chest or bed is to lure them with raw fish, place glass blocks over it, or create a piston device to push them away. Wolves will not attack cats, tamed or otherwise. Due to a bug, cats and dogs can, in rare cases, teleport close to the player for no noticeable reason. This may be intentional to prevent them from getting stuck or unable to follow the player along the same path. Creepers will run away from cats as if they are afraid of them. A standing cat can still breed with a sitting cat, but the kitten will always have the same pattern as a standing cat rather than a sitting cat. If there is a window in the house, the cat may sometimes look out of it. . In Europe, reminiscent of the mini-Panther Bombay, as a true rarity among domestic cats.

Sailors also have characteristic beliefs associated with a black cat. If there is a black cat on the ship, the voyage will go without any problems. But if you throw this animal overboard, an unprecedented storm will break out.

Black cat: signs and superstitions.

The cat's body is narrow, but still muscular. Expressive yellow or green eyes are far apart. Typical of the Bombay are their large and slightly slanted ears, as well as their long, thin legs. Animal fur is smooth and shiny. The history of Bombay was founded by American plant breeder Nikki Horner. Their goal was to breed a domestic cat that was similar in appearance to the black panther and could rival Burmese cats in terms of wisdom and charm. It attempted to reach the breeder through the crossing of the American Shorthair with Burmese cats.

Korat

And here is the Korat - another rare and ancient breed: a photo of a gray cat with green eyes will not leave any Thai indifferent. The name itself is consonant with one of the provinces of Thailand, and for good reason. A great many national traditions and beliefs are associated with this cat. According to local residents, korat brings prosperity, wealth and success.

The coat of cats of this breed is thin and not thick, like that of Russian Blues and Nibelungs, but has the same color - silver tipping with a characteristic iridescence. The eyes of a Korat cat are large and round, and the color of the iris is olive green. Other coat and eye colors are not allowed by the standard.

Emerald iris color is rare

Initially, the most common eye color for cats with any coat was green.
But subsequently, breeders became somewhat carried away by breeding new breeds with unusual eye colors: blue, bright orange, etc. Therefore, today, unfortunately, cats with green irises have become a relatively rare occurrence. There are quite a lot of furry animals with tea-colored, marsh or, for example, khaki-colored eyes. But cats with emerald green or bright grass irises are very difficult to see today.

But still, if you try, you can find a cat with such eyes even today. Even an outdoor cat can have a bright emerald iris. Of course, this eye color is allowed by the standards of many breeds.

Causes of yellowing eyes in cats

Yellowing of the sclera in a cat is not noticeable due to the large size of the iris. Even an attentive owner notices the icterus in the whites of the animal’s eyes against the background of a general deterioration in the condition of his pet, a change in his appetite or yellowing of the inner surface of the ear or the skin of the pads. Not only the sclera or the lining of the ear turns yellow, the cat’s entire skin changes color, the tongue and all visible mucous membranes become lemon-colored. This condition is called jaundice.

Jaundice, as a symptom, always indicates a high concentration of a substance such as bilirubin in the animal’s blood. It is a derivative product during the normal processing of hemoglobin from red blood cells, which the body needs to transport oxygen to every cell and organ. If hemoglobin is processed at an accelerated pace (under pathological conditions), then soon too much bilirubin will accumulate. Then yellowing of the whites of the eyes and mucous membranes occurs.

In addition to jaundice, your cat will have other signs of illness:

  • indigestion;
  • flatulence;
  • diarrhea or vomiting;
  • extreme thirst and excessive urination;
  • labored breathing;
  • hepatic encephalopathy;
  • dark urine and light feces;
  • Also, in the last stages of the disease, the animal may experience internal bleeding, and, as a result, blood in the urine and feces.

This condition is far from normal. The animal eats poorly, loses a lot of weight, may suffer from severe pain, and fall into a coma. In the absence of timely medical intervention, the pet may die.

Such a manifestation as jaundice is usually differentiated into parenchymal, mechanical or obstructive and hemolytic forms. Each form is caused by serious pathological processes in the cat’s body:

  1. Hepatic or parenchymal jaundice is caused by functional and organic diseases of the hepatobiliary system. Hepatitis (inflammation of the liver parenchyma), cholangitis (inflammation of the bile ducts) cause icterus in animal tissues.
  2. Severe liver diseases: cirrhosis (replacement of the organ parenchyma with connective tissue with loss of its functionality) and cancer lead to yellowness of the skin and mucous membranes. Even excessive accumulation of triglycerides (fats) by liver cells - hepatocytes - leads to yellowness of the sclera and skin.
  3. Baked obesity, or lipidosis. In this condition, liver cells develop into fat cells. The liver gradually loses its functions, which means the animal may die. Its causes are the cat's excess weight, diabetes, malignant tumors, and hyperthyroidism. Unfortunately, in almost half of the cases the cause of this dangerous disease cannot be established.
  4. The use of certain medications can lead to changes in the liver and excess bilirubin (bile pigment) in the cat's blood. It is the bile pigment that colors tissues a beautiful yellow color. These medications include: first generation antihistamines (diazolin), NSAIDs (paracetamol), antifungals (griseofulfin).
  5. Infectious diseases of viral etiology (viral peritonitis), protozoal infections (toxoplasmosis), bacterial pathologies and some parasitic infections cause liver pathology and the release of large amounts of bilirubin into the blood.
  6. Incorrect use of insectoacaricides (veterinary products intended to combat parasitic insects, in particular ticks). Many insectoacaricides have a strong toxic effect on hepatocytes. Salts of heavy metals also have a similar effect.
  7. Obstructive jaundice. Obstructive jaundice develops when there is an obstruction to the outflow of bile. Most often it develops due to exacerbation of cholelithiasis (cholelithiasis). If concretions (stones) block the bile duct, the animal develops biliary colic, the temperature may rise, and it is bothered by severe pain in the right hypochondrium. The mucous membranes, sclera and skin turn yellow.
  8. Inflammatory diseases of the gallbladder and its ducts, their stenosis, pancreatitis, pancreatic cancer can lead to impaired outflow of bile and jaundice. Any tumors of the abdominal cavity that grow into the tissue of the bile ducts or mechanically compress the gallbladder and its ducts can cause large amounts of bilirubin to enter the bloodstream and cause yellowing of the animal’s tissues.
  9. Hemolytic jaundice. Hemolytic jaundice is caused by hemolysis (destruction) of red blood cells directly in the blood vessels. This happens in some diseases (hemolytic anemia). The cause of hemolysis of erythrocytes may also be severe hypophosphatemia, aggravated by magnesium deficiency. Hemolysis can develop as a result of a cat’s body’s reaction to a blood transfusion. The entry into the blood of hemolytic poisons (zoocoumarin) and medications (warfarin) also leads to the destruction of mature red blood cells.
  10. Parasitic diseases: feline hemobartonellosis, feline piroplasmosis can lead to hemolysis of hemoglobin. Parasitism of certain helminths that attack vital organs can lead to hemolytic jaundice. This disease in veterinary practice is called dirofilariasis.

Feeding white cats

Of course, it’s nice to pamper your pet with delicious treats, including vitamins, especially considering how many of them can now be seen on the shelves of pet stores.

However, you should not rush to make a choice.

  • Danger No. 1 - economy class food. Such foods contain a large percentage of dyes and flavors that make this food as attractive as possible to animals. Alas, these same dyes can have cellular permeability and, if they enter your pet’s body, they can color the tear fluid, and sometimes the fur that grows during the period of feeding these “treats.”
  • Danger No. 2 - allergies. Any food can cause allergies, especially in white cats that are susceptible to this scourge.

The consequences are quite obvious: an allergic reaction often leads to allergic conjunctivitis. Conjunctivitis, in turn, causes excessive lacrimation. Excessive lacrimation leads to wetness of the fur of the infraorbital region. Bacteria develop on wet wool, the waste products of which cause a change in hair color.

Danger No. 3 - feed composition. Moreover, this danger does not depend on the class of food.

Food may contain substances that change the color of not only tears, but also the fur itself:

Meat: Some cats experience yellowing of their saliva and tear fluid from beef and chicken dry foods.

Additives: some foods contain ingredients that are beneficial for most, but, alas, undesirable for white cats, such as seaweed, beet pulp, carrots, and liver. Similar components, but in higher concentrations, are often included in treats and vitamins.

This is something to pay attention to. And yet, it is necessary to keep in mind that some white cats will experience darkening, while some will avoid this fate

For lovers of “natural” food, the taboo should extend to liver, carrots and buckwheat.

Fat: Too much fat in the food often causes the coat to become overly greasy. Besides the fact that outwardly this does not make a very pleasant impression, and oily fur can never appear snow-white, there are even less joyful consequences of such feeding.

Firstly, oily wool sticks together and, as a result, more often contributes to the formation of tangles. Secondly, for the same reason, the moisture content of this wool is much higher than normal.

We'll talk about what this leads to a little later. And the most obvious fact: oily wool attracts all the surrounding dirt like a magnet.

What to do?

  • Feed your pet only professional food, avoiding economy class products.
  • Carefully study the composition of the food, avoiding those varieties that contain “coloring” ingredients.
  • When switching to a new food, carefully monitor your pet’s well-being, noting changes in condition, coat color, color of discharge from the eyes, and behavior.

Singapore

According to legend, this rare breed of miniature cats comes from Southeast Asia. Singapura cats have a very unusual coloring - sepia agouti. The ivory body is complemented by dark brown ticking, giving the coat a sandy tint. Singaporeans are characterized by not only yellow, but also yellow-green, as well as bright green eyes. You can learn interesting facts about this breed from our article “Singapore cat and more.”

Orientals

This is another breed that is definitely worth considering for those who want to have a black, green-eyed pet. A feature of Orientals is, first of all, a very unusual “lynx” appearance. Their muzzle and ears form an inverted triangle. These cats have shiny fur and look very elegant and graceful.

One of the characteristic colors for this breed is ebonite, that is, coal-black. Orientals with such fur usually do not have a single light spot on their body. Even the nose and paw pads of these cats are black.

The character of Orientals is quite flexible. These cats adore their owners and constantly demand attention from them. One of the characteristics of this breed is its loud voice, which Orientals love to use with or without reason.

Green eyes in Orientals, including blacks, are quite common. Moreover, the iris of such cats can have a variety of shades - from swamp to bright grassy. The eyes of animals of this breed are large, almond-shaped. That’s why orientals with a green iris look incredibly impressive. A photo of a black cat of this breed is presented below.

Khao Mani breed: distinctive features

The snow-white cat from Thailand, called Khao Mani, or diamond eye, has a very ancient pedigree. It is easier to care for such a cat than a Persian, because it is a short-haired breed. This species got its name because of the special cut of the eyes - they are brightly outlined and shine like diamonds.

It is better not to get this cat for those people who are rarely at home, because she does not like loneliness and does not tolerate it well. In character, cats of this species are closest to Siamese.

Scottish lop-eared

A blue-eyed Scottish kitten is the dream of any breeder or just a cat lover. The eye color of kittens is determined primarily by color and, of course, heredity. Celestial blue eyes are a virtue found in both dominant white and albino kittens.

A blue-eyed Scottish kitten is the dream of any breeder or just a cat lover

The Scottish Fold cat is white with blue eyes and looks like a small charming child who you want to cherish and protect.

If the kitten had blue or black ancestors in the family, then the Scotsman may have a few dark spots on the head, but with age the fur lightens and eventually becomes completely snow-white. A Scotsman's eyes can also be amber; there are also cats with different eyes. The great advantage of this species is its gentle disposition, lack of conflict, ability to compromise, affection and gentleness, which makes it possible for them to live together with both children and the elderly.

Abyssinian breed and Somalia

These ticked cats also have green or yellow eyes. The main thing, as the standard says, is that their color is intense, without intermediate shades. We wrote more about the characteristics of Abyssinian cats here.

Somalis are long-haired relatives of the Abyssinian cat, so their eye color options are the same as those of the Abyssinian cat.

Norwegian Forest Cat

A large black cat with green eyes of the Norwegian Forest breed is incredibly beautiful, although it is quite rare. Much more often, representatives of this native breed have common colors with agouti factor and white. The Norwegian Forest is a semi-long-haired cat, and its truly long, thick fur once helped these cats survive in the harsh Scandinavian climate.

The breed standard allows all green shades of the iris, including yellow-green.

Cornish Rex

A charcoal coat also adorns representatives of the Cornish Rex breed, emphasizing the extraordinary wavy structure of the coat and giving the cat a special elegance. The breed standard allows any eye color, but the color of the iris must be pure, intense and in harmony with the coat color.

Ragdoll

This cat is just perfect for those pet lovers who want to have a calm and affectionate pet. Representatives of this breed are distinguished by their phlegmatic and lazy character. Even the name “ragdoll” itself translates literally as “rag doll.”

The weight of a cat of this breed can reach up to 9 kg. That is, these animals are very large. Ragdolls have a fur structure that is unlike any other cat. Since representatives of this breed have very thin hairs on their bodies, their fur is more reminiscent of a rabbit's.

Actually, black is not included in the standard of this breed. However, ragdolls with dark coffee or black-chocolate coat are allowed for exhibitions. These cats look almost jet black. Pets with green eyes of the Redgall breed are also quite common.

Breeds of chinchilla colors

This group includes all tipped (shell) and shaded (shaded) colors, both silver and gold. All cats with chinchilla coloring have emerald eyes, or an aquamarine and blue-green iris (the exception is cats with red pigment, their eyes are yellow or copper).

The combination of emerald eye color with silver and gold fur looks great, especially considering the expressive eyeliner and nose. This color is found in Persian and exotic cats, as well as in British and Scottish fold cats.

Black wool: features

This fur color initially is also not uncommon for cats. The coat of a purebred cat may appear black if its color is defined as:

  • jet black;
  • dark chocolate;
  • silver-black;
  • black and blue, etc.

Fur of this color, as well as emerald eyes, are acceptable by the standards of many modern breeds. Of course, you can also have an outdoor kitten at home with this combination of fur and eye color. But you can, of course, only find such a pet with a certain amount of luck. Genes in street cats manifest themselves extremely unpredictably.

Turkish Angora: characteristics of the breed

There are various breeds of white cats, but perhaps the most famous of them is the Turkish Angora - a harmoniously built, flexible and graceful animal with large, almond-shaped, wide-open eyes, set somewhat obliquely. Originally, this type of cat was only white with blue, orange, green, amber, yellow or different colored eyes.


There are various breeds of white cats, but perhaps the most famous of them is the Turkish Angora. The tail of this beauty is much longer than that of other breeds, resembles a peacock feather and can reach the shoulders.
This breed was formed in Turkey, where it is still highly valued today. Cats with different eyes are especially valued, despite the fact that white Angoras with different-colored eyes are deaf in the ear on the same side as the blue eye.

Albino cat appearance

Not every white cat can be considered a complete albino. It should be remembered that this is a genetic mutation, the presence of which can be determined by the color of the coat, paw pads and tip of the nose. There should be no pigment on any of these areas of the body.

The most important sign of a true albino is the color of the iris. Full albinos have red, pink, or pink-blue eyes. Translucent vessels can be seen through the iris. If the iris is well colored in blue, green and other colors, then such an individual has partial albinism. Among cats, complete albinos are extremely rare. It is believed that one complete albino is born among cats per 10 thousand individuals. At the same time, there are breeds among which albinos are much more common. This is due to their genetic characteristics.

Silver tabby cats

Quite often, green eye color can be found in silver tabby cats (British, Scottish, American Shorthair and many other breeds, as well as in ordinary, but no less charismatic yard cats). However, in comparison with chinchillas, it is not nearly as rich and bright. Most likely, breeders, paying great attention to the quality of the color itself, its pattern, have not yet had time to pay due attention to eye color.

Let's make a reservation that silver tabby cats and cats are also characterized by yellow and yellow-green eyes.

Signs associated with ginger cats

Red cats, just like black ones, are haunted by all sorts of legends.

  1. It is believed that red pets are always obstinate and overly independent. In fact, there is often a very strong emotional connection between an animal and its owner.
  2. Picking up a ginger kitten on the street and bringing it into the house means attracting prosperity and good luck. Since the fiery color is no more common among street vagabonds than among their purebred relatives, not everyone will experience such happiness.
  3. Some people believe that a sunny-colored cat absorbs negative energy and protects a person from negative influences.

They also say that they purr louder than others, cure alcoholism, and predict illness and death. The only true observation is expressed in the popular saying “a cat in the house means happiness in it.”

What determines the color of a cat's eyes?

All kittens are born with blue eyes, and only after a few weeks the color of the iris begins to change. What is this connected with? The iris consists of two layers - mesodermal and ectodermal. In the anterior part there are chromatophore cells that contain the pigment melanin, which is responsible for eye color.

The lower the amount of melanin in the iris, the lighter the eye color. There is almost no pigment in blue irises, a little more in green eyes, and cats with golden eyes have the most coloring pigment.

The color of the iris is inherited. Just like coat color, it is associated with a combination of different genes. Inheritance occurs according to a complex pattern, so even experienced breeders cannot accurately predict the color of the eyes of future kittens. Looking at his parents, it is possible to predict the color of the iris in 50–60% of cases.


Heterochromia in the Angora cat

Heterochromia is an unusual phenomenon that occurs not only in cats, but also in humans. In this case, the color of the left and right eyes is different - one of them is blue, and the other may be green or golden. This feature is due to heredity.

Features of white blue-eyed cats

Owners of white cats note their extraordinary modesty and even shyness. Despite their bright appearance, these beauties are absolutely not arrogant or arrogant

They need increased attention and care from their owner. And if strangers often appear in the house, ask them to be as correct as possible and not to frighten your pet - she is suspicious and too vulnerable, and she absolutely does not need unnecessary stress

A white cat can be modest and even timid

Is it true that they are deaf?

The statement that all white blue-eyed cats, without exception, suffer from hearing loss is not true, although such cases are not uncommon. Research by genetic scientists, based on the extensive practice of various breed nurseries, states: a third of these cats do not have any hearing problems. Darwin also noted the connection between the deafness of cats and their white color and blue eyes.

The “culprit” of the deafness of a white cat is the influence of the dominant allele of the W gene, which at the early embryonic stage not only forms the white color of the kitten, but also blocks the growth of cells of the organ of Corti - the peripheral part of the auditory analyzer, its degeneration and becomes the root cause of the animal’s deafness. This is a rare case when one gene forms not one, but several traits - this phenomenon is called pleiotropy.

Even if the kitten can’t hear, he will definitely bring joy to your home.

You shouldn’t refuse to buy a kitten you like just because he can’t hear. But, of course, only if you do not plan to exhibit this animal or use it for breeding. Breeding work with deaf individuals is prohibited in all breeds. And responsible owners should give up the idea of ​​“getting kittens” from their deaf pet. It would be better to spay or neuter such an animal.

You should not keep a deaf cat on a walk, and if you walk with it, do so only on a leash. The risk of getting lost and dying for a deaf cat is very high, and this should always be kept in mind.

Proneness to diseases and other problems

Like all white animals, cats have very sensitive skin. They are prone to allergies and various dermatoses. Overly loving owners who now and then pamper their pet with a variety of “human” treats should remember this feature. Any food from the master's table is a definite taboo for cats in general, and even more so for white cats.

Here’s what you absolutely can’t treat them with “tasty”:

  • sweets and fresh pastries;
  • peppered, salted and seasoned with any spices;
  • smoked, fried and pickled;
  • sausage and cheese;
  • chocolate;
  • citrus fruits.

Sunbathing is not good for a white cat

The delicate skin of a white cat can also suffer from external unfavorable factors - for example, from drafts, frost or, conversely, heat - each breed has its own risk zone. But for all, without exception, “snow whites,” direct sunlight is dangerous. Protect your cat from them - a tan will definitely not be good for her

Severe dermatoses can also be caused by bites of various insects, so it is especially important to promptly treat white cats against all types of parasites.

These animals often have problems with bone tissue, which can cause the development of diseases of the musculoskeletal system and the dental system.

Veterinarian examinations should be regular

What are the differences between albino cats?

White cats with blue eyes are not albinos. Albinism is expressed in the absolute absence of pigment. Such cats not only have white fur, but also red eyes, and the skin under the fur is always painted pink. Blue eye color indicates that there is pigment - it colors the iris of the eye.

Both the eyes and skin of an albino cat are pink.

Albinos have the weakest immunity of all white cats. Drafts, hypothermia or overheating, contact with sick animals and other provoking factors are especially dangerous for them.

In addition, the nervous system of albinos is characterized by increased sensitivity, and this is important to take into account when creating conditions and a comfortable living regime for them.

A comfortable lifestyle is very important for an albino cat.

Breeds of long-haired cats: the beginning of history

There are two versions of the origin of long-haired cats:

  1. In the cold northern climate, long hair protected from frost and helped animals survive the long winter.
  2. Representatives of the southern regions acquired a long-haired coat to improve heat exchange - a thick layer of hair prevented the cat’s body from overheating in direct sunlight.

Later, in the 19th century, there was a great migration of cats to the European continent, where interbreeding began.

This is interesting! There are more than 250 cat breeds in the world, a third of them are long-haired animals.

Breeds for which only gray coat color is acceptable

Blue coloring is standard for some cat breeds. They must have a perfectly even, so-called “solid” coat color. Only in kittens are uneven colors allowed, which fade with age.

Breeds of gray cats:

Russian blue

The ancestor of the Russian Blue was the Arkhangelsk cat, which was brought to England in the 18th century. In its current form, the breed was formed at the end of the 19th century.

These are short-haired cats with almond-shaped green eyes, a flat muzzle and a gray coat with a silvery sheen. The paw pads are oval and have a lilac-pink color, and the inner surface of the pointed ears is a soft pink shade.

The Russian Blue cat is characterized by a muscular and slightly elongated body, long legs, a triangular head, and a tail pointed at the tip. Their coat is silky to the touch, erect, double - the length of the hairs of the undercoat coincides with the length of the coat. Because of this, the cat’s skin resembles plush.

Nibelung

The first Nibelung was born from two individuals that did not fully meet the Russian Blue standard due to their semi-long coat. Their names were Siegfried and Brünnhilde - these are the names of the heroes of the "Song of the Nibelungs". The breed was created in 1984.

In addition to the length of the coat, the Nibelung differs from the Russian Blue in the color of its nose - it is gray-blue in color, as well as the paw pads - they are gray-pink. Acceptable eye colors are green and amber. The fur on the nape forms a small “collar”. These cats have a very quiet voice.

Korat

The Korat breed is one of the oldest. Initially, blue cats lived high in the mountains of Thailand, on the Korat plateau. They appeared in Europe in 1896, but it was not until 1966 that they were recognized by the American Cat Association. The World Cat Federation recognized them in 1982.

These are muscular, but not massive cats with legs and a tail of medium length. The tips of the ears and tail of the Korat are rounded. The eyes are round, large, set wide, olive green in color, amber color is also allowed. Like the Russian Blue, the Korat's fur has a silvery sheen, but is not thick and is of medium or short length. The undercoat is shorter than the center hairs, the coat lies closely to the body.

Chartreuse

Chartreux cats, natives of the Middle East, appeared in Europe back in the 16th century. They began to breed them in the French monastery of Grande Chartreuse, which belonged to the Carthusian order. This is where both names of the breed came from - Chartreux or Carthusian cat.

Application

The ancestors of the Russian Blue hunted in the harsh northern climate.

And although today these felines do not have to think about food, they have retained their hunting instinct.

These cats hunt wherever they can. Even in the city, the Russian Blue finds an object of hunting: it catches flies, mosquitoes and butterflies.

She can watch for mice for hours.

The bouncy and curious Russian Blue loves to play. She uses everything she can find to play. These could be toys or different things.

Features of temperament and behavior

If you compare the characters of breeds that, according to the norms, are supposed to have a gray color, you will notice some similarities in their features. Gray cats are independent, self-sufficient, and will not constantly demand the attention of their owners. They are distrustful of strangers, at first they behave coldly and unfriendly towards them. Nibelungs can even show aggression towards guests; other breeds are less warlike, but no less wary of strangers.

At the same time, all breeds are affectionate with “their own”, sociable, although some of them “listen” more than “talk”, but they make contact - and sit next to them, and pose for photos, and are clearly interested in their person. But these are not the most tactile cats, especially Chartreuse cats. They don’t like to sit in your arms or try to pester them with affection when they don’t want to, but they are patient, especially with children, and won’t scratch. And the Russian Blue does not release its claws at all when interacting with a person.

Gray cats are calm, balanced, delicate, and accommodating. Korat, for example, is very loyal even to dogs if they do not try to attack him. All breeds readily interact with children; even the Russian Blue forgets its manners and happily runs around with them. Chartreuse is too lazy for outdoor games, but will tolerate it if children begin to carry it in their arms. But the playful Korat will actively participate in all the pranks.

Care and maintenance

Oriental cats do not have an undercoat to protect them from the cold. Therefore, it is advisable to keep them in warm rooms where there are no drafts. Otherwise, caring for them comes down to basic hygiene and periodic washing.

  • The Oriental's eyes and ears are regularly wiped with a cotton pad moistened with boiled water or a special product purchased at a pet store.
  • The cat's claws wear down on the scratching post. But if necessary, they are carefully shortened with a nail cutter, trying not to injure living tissue.
  • Oriental teeth are brushed weekly with a silicone brush and non-foaming paste. This simple procedure will help get rid of plaque and prevent the formation of stone on your cat's incisors and fangs.
  • The fur coat of a furry pet is regularly combed with a special brush or rubber mitten. An Oriental Shorthair cat is simply wiped with a piece of clean, damp cloth. Representatives of the breed are bathed no more than 3-4 times a year. This is done using a special shampoo that matches the animal’s coat type.

American Bobtail

A distinctive feature of this cat is its bob tail. Representatives of this breed look very funny. Breeders often sell black American Bobtails with white spots on the face or chest. According to breed standards, this is not considered a marriage. Black and white cats with green eyes also look quite impressive.

The standards for this breed recognize 3 shades of black:

  • dark chocolate;
  • carbonic;
  • black and ash.

These cats are considered a family breed. They treat all people living in the house equally with love. Bobtails do not require too much attention from their owners, but they will also take part in active games with pleasure.

Health

Russian Blues, like Norwegian Forest Cats and Egyptian Mau, were not bred artificially. They belong to natural breeds.

Therefore, they have strong immunity and good health. They live a long time and very rarely get sick.

Russian Blues are not afraid of drafts and cold temperatures. They do not have any genetic breed diseases.

Although they, like other felines, can suffer from diseases typical of cats.

Vaccinations

For the first eight weeks, kittens are protected by maternal immunity. The kittens are then vaccinated.

Only healthy animals can be vaccinated.

Suitable age is 2.5–3.5 months. For this purpose, combined vaccines against rhinotracheitis, panleukopenia, and calcivirus are used.

Vaccination takes place in several stages. Interval – 3–4 weeks.

Before vaccination, kittens are given anti-worm medications.

Russian Blue is one of the most hassle-free cats to keep.

After a month has passed from the date of the last comprehensive vaccination, kittens are vaccinated, like dogs, against ringworm.

The rabies vaccine is given at 3–4 months of age. It must be repeated annually.

British and Persian

The muscular and squat Briton has the largest palette of eye shades: from blue to dark copper, and in a white cat with different eyes, one eye can be blue and the other gold.

Persians can also be snow-white and blue-eyed, although standard Persians have the right to 3 eye color options: blue, orange and different, when one eye is blue and the other is orange.

Considering the length of Persian hair and the white color of the coat, you need to understand how long it will take to care for such an animal, and what a labor-intensive process it is. But Persians do not cause any other trouble: they are phlegmatic, even lazy, and lie calmly in one place for hours.
