Tell me, please, when did your children change their eye color ?. Our eyes are blue and we all look in order not to change.
Discussion
We were born with blue and blue, and by 3-4 months we became gray-blue. I hope that they will remain so. Dad and Mom are the same.
We were born with dark gray, by the 4th month they darkened and now are brown. I read somewhere that the color that is set to 6 months and will last for life. I just do not know if it's true.
we will soon be. Photos of last year's album. Now all with straight ears, a dark gray striped girl, a gray-blue girl, two beige boys, and a redheaded boy

When they begin to cling and prevent the kitten from playing (literally - when hooked "crochet" to the couch and can not unhook without your help)

The answer to the question allows us to give an understanding of the genetic foundations of anatomy of cats, the physiological processes of development of kittens and physics. Like all mammals, kittens are born not fully formed. Some organs continue their formation for some time after birth. One example of this development is the change in eye color as the kitten grows. The final, adult color, programmed genetically, cat eyes get gradually.
Eye color depends:
- From the degree of concentration of a substance called melanin in the iris of the eye. Melanin - this is a dark brown pigment, which is also present in the cat's fur. It forms cat color - gives wool a color and creates a pattern.
- From how light passes through the eye and dissipates in it.
Melanin is produced by special cells of the cat's body. At birth in the iris, the kitten of melanin is rather small.
Why does a small amount of dark brown pigment in the iris give it a blue color? The answer to this question is the answer to the question of why the kittens blue eyes.
The physical explanation is quite simple. In the rainbow for the red, orange and yellow color "answer" waves with a long wavelength. Short waves are perceived by us as a blue color. Melanin absorbs well the long-wavelength part of the visible spectrum, giving the eye color.
The shortwave part of the light is scattered in the iris of the eye, just as it does in the atmosphere. Since melanin is not required for this, the cat's eyes (like the day sky) turn blue.
Thus, the blue color of the eyes is not associated with the presence of some "blue" pigment in the iris, but due to the usual laws of physics.
With age, the amount of pigment in the eyes reaches the norm and the iris acquires the final color. In most cats, the eyes have a color from greenish-yellow to golden.
Some cats have a different color. For example, siamese cats eyes blue , this is due to the action of one of the forms of the gene of albinism, which leads to the discoloration of the coat and iris of the eyes.
Cats with white areas in the colors of wool (bicolors) also sometimes have blue eyes. White spots are encoded by the piebald gene (piebald gene, white spots), which also affects the color of the eyes.
Have completely white cats eyes are blue, this, as well as the white color of the coat, is the result of the absence of pigmentation.
Sometimes the gene for white spots causes a lack of pigment in only one eye, while in the second the normal pigmentation remains - so the disagreements between cats (with different eyes) are obtained. This effect can be observed in fully white cats. For example, famous cats breeds Turkish Angora are very popular, including, and because they often have one eye blue (no pigmentation), and the other is yellow or golden.
A noticeable number of white cats suffer from deafness . Deafness is caused by the same gene that leads to the white color of the coat. It is believed that the deafness of white cats is associated with a lack of pigment in the structures of the inner ear.
Expressive eyes of cats from the ancient times admired people. This piercing, sharp look, which at the same time can be and affectionately-asking, and a little tricky. But it is even more interesting to consider what color the eyes have in a cat.
The color of the cat's eyes is very interesting and can range from yellow-amber to green and even blue. So far, scientists have not been able to scientifically prove whether it is related to genes that are "responsible" for coloring the animal's fur. However, there is a definite connection between point and white cats and the color of their eyes.
The color of the cat's eye determines the presence of a special pigment. In most cases, for any color of the cat's fur, there can be any color of the eyes. But for purebred cats, only a certain color is allowed. Obtaining individuals with the right eye color is the main difficulty for breeders. However, breeders, through complex and painstaking efforts, achieve incredibly accurate and correct eye shades in pedigreed cats. Usually, the eyes of cats do not come in solid colors.
The right and so different
In mongrel cats, brown eyes often occur. Blue eyes are endowed with fluffy beauties and beauties who have a white coat color or with the presence of white in color - white, light cream, with spots of white, colorpoints.
All newborn kittens have blue eyes. Then the color can change and even fade.
The correct colors of the eyes in cats are those that are in the spectrum, from green to copper. In this case, each particular color may have intermediate shades, especially in non-pedigree cats. In thoroughbred, as a rule, it is more limited.
Green color can lie in the range from the color of ripe gooseberry to emerald. Shades karego can be walnut and dark green-yellow. A golden color can wear a dark yellow tone, which has a greenish tinge. Yellow can be amber or yellow-orange, and orange bright-orgazhevym. Copper color sometimes acquires a copper-orange saturated shade.
Unique and wonderful
If the amount of pigment is reduced in the color of the coat, then this will manifest itself in the color of the eyes. Thus, the cat's eyes can be chocolate, lilac or shades slightly paler.
It is appropriate to say about the special colors of cat eyes, which are also obtained due to reduced pigment density. They do not change shades, passing into each other, but only change the intensity. This, for example, is sky-blue and sapphire, inherent only in Siamese cats. The turquoise color of the eyes, which is endowed only with thin cats. A unique blue-green color, observed in cats of tippirovannyh colors.
In addition to special, sometimes cats can have eyes of different colors. Such an unusual color of the eyes can be enjoyed by white non-albinos and some cats that have a coat color with white spots. As a rule, one eye - blue, and the other - colors from the group of the right shades. And also cats have abnormal colors, for example, cornflower blue. This is quite a miracle of miracles.
But, it does not matter what color the eyes have in a cat, because they are still unusually beautiful, like their owner or possessor.
The best tricks with cats - video
Normal color of eyes in cats in the range from blue to copper; if an abnormal eye color appeared in a cat unexpectedly, then this may indicate the presence of serious health problems.
Before, to look for the causes of abnormal eye colors in cats, let's take a closer look at what is considered the norm. You probably know that the vast majority of kittens are born with blue eyes, the color of which changes and reaches its constant shade by the age of 3 months of the animal. The color of the eyes in an adult animal depends on the number of pigment cells in the iris known as melanocytes. Cat's eyes of different colors, with strange patterns, or those that change color in adulthood, can signal health problems.
Cat's eyes
What color is the cat's eyes? General rule for cats, the color of the eyes is genetics, the less the amount of melanocytes, the lighter the shade, and the more, the darker and deeper they will be. Of all the variety of shades and colors of cat eyes, you can still distinguish the main four: blue, green, yellow, copper.
At the same time, blue eyes do not really have eyes in cats, cats with blue (blue) eyes have very little pigment, so the blue color of the eyes is just a reflection in the transparent part of the cat's eye. We can observe a similar illusion if we look at a window glass at a certain angle. There is no significant relationship between the color of the cat's eyes and her health or longevity. Let's now analyze why the color of the eyes in a cat can change or seem unusual.
Heterochromia of the iris, or different eye color in the cat.
Agree, interesting and intriguing look cats with multi-colored eyes. What are the causes of heterochromia in cats? The answer is genetic, this gene affects not only the color of the eyes, but also the color of the coat. Any cat can be the bearer of this gene, there is no specific breed of hair color, which directly indicate the presence of colored eyes in cats. And the most important heterochromia is not a disease, it does not affect the visual acuity and other vital indicators in any way!
There are different types of heterochromy. And one of them occurs most often - it is complete heterochromy - a condition in which one eye contains more melanocytes than the other, which leads to the fact that the eyes of the cat have their own color, and are painted completely. For example, one eye is completely yellow, the other is green.
Partial heterochromy is less common.
Partial heterochromy is when one eye in a cat, half green, and half blue are colored in different colors.
There are two types of partial heterochromy.
Central heterochromia: the area of the iris closer to the pupil is surrounded by one color, and the rest of the iris is of a different color, or a noticeably different shade.
Sectoral heterochromia: there is a spot or patch of the iris that is colored in a different color.
There is an opinion that cats with blue eyes or a cat with one blue eye, suffers from deafness, but in practice it happens that deafness was associated with the color of the eyes. According to statistics, really cats with blue eyes, or with multi-colored eyes are more susceptible to hearing-related diseases, but neither blue eyes nor heterochromy, does not mean that your cat's ears are in danger.
Uveitis in cats.
During the first three months of life, the color of the eyes in cats develops and acquires its final shade. Some cats may have multi-colored eyes, while others may have one eye with two distinct colors. Change in the same color of the eyes adult cat is an alarming sign as it may be a signal that the cat has serious health problems. Uveitis, or inflammation of the choroid of the eyeball, can cause a significant and sudden change in eye color in cats.
Waves in cats are rare, as a separate disease, most often it is a symptom of any other health problems requiring veterinary consultation and treatment. The color of the eyes in a cat with uveitis can suddenly change color, sharply grow dull or blush from irritation. Here are a few of the most common causes of eye discoloration:
Physical trauma: direct eye damage can cause irritation of the choroid of the eyeball.
Systemic diseases: diabetes, pressure problems, etc.
Autoimmune diseases: feline immunodeficiency virus
Cancer: discoloration can indicate the development of cancer, a diffuse eye especially melanoma and lymphoma
How to treat uveitis in cats, depends on what is its cause. Changing the color of the eyes may not be a pronounced symptom, so it is worthwhile to take the cat to the veterinarian if she starts blinking rapidly, rubs the affected eye or eyes repeatedly, or walk with one closed eye. Uveitis is contagious only if its cause is viral infection.
Glaucoma in cats.
Previously, we set the range of standard eye colors. The environment of these was not mentioned in white, since it is certainly abnormal in cats. Under normal conditions, blood and other fluids circulate through the eyes of the cat. When these fluids are blocked for some reason or their movement slows down, the intraocular pressure begins to accumulate. Which is the reason for the white color of the eyes (glaucoma) in cats. This disease can affect not only sight, but also the mood of the animal, temperament, activity and appetite can change. The classic symptom of glaucoma is white, cloudy or milky in the eyes of cats. Not surprisingly, glaucoma is also one of the causes of uveitis.
Suddenly, the color of the eyes changed in the cat? Call the vet!
It is common knowledge that the eyes are a mirror of the soul, and we all know that cats are mystical creatures and a mystery is reflected in their eyes. My cat looks at me intently, when he wants to be fed or caressed. Unlike people, the process of physical growth and maturation, as a rule, is accompanied by a change in eye color. Some breeds of cats, in accordance with the standards, can have only one specific shade of the eye, for example, the Russian blue should only have a green eye color, while in Siamese cats the eyes should be blue. If an adult cat suddenly changes its eye color, this may be a sign of serious illness, so contact your veterinarian as soon as possible!
1. Very much I want a kitten of color Whiskas, but the red color of eyes is not pleasant. Tell me, are there kittens with a different eye color?
Answer: Kittens with a different color of eyes are, but not British. The British breed of cats allows a copper, orange, amber eye color. Green eyes are only allowed in chinchillas.
2. Three months ago we found a kitten. She is very similar to a British kitty. But we do not really know. Can this be checked? Thank you.
The answer is: your kitten may look like a thoroughbred, but if he does not have a pedigree, neither he nor you will benefit from what he looks like to someone else.
3. Do all british cats "straight nose? For example, my nose is almost the same as the Persian "flattened." There is a pedigree. Is this normal for a Briton?
Answer: there is a certain standard for British noses: they should not have a "stop," like the Persians. Although with the Persians, the British used to be knitted, but at present it is forbidden by all felinological organizations. According to the genealogy, you can see whether there is a Persian track far away.
4. If the kitten has a different eye color, is this normal? And will they be the same color when he grows up?
Answer: the color of the eyes in kittens should be the same. If they started to burn out due to age-related changes, then a slight difference can be. But if the eyes are completely different, they will remain so.
5. Tell me, please, at what age does the color of the eyes change in British kittens? And what is the standard color of an adult cat?
Answer: British kittens are born with gray-blue eyes. At 3-4 months, the eyes begin to burn out, i.e. change its color. First they become marshy, then tobacco, then to half a year they are nutty. The final color is set to 10 months for the British, it happens in all shades of amber: from light to saturated orange to quite dark honey.
6. I want to take a kitten. The problem is that according to the pedigree he is British. His parents are British by bloodline. But! At the daddy of a kitten in 3 knees in a family tree there is a straight! Is this kitten British by the new rules? Even if he is already registered in the club, like a Briton? It's just that some breeders start to confuse me and say that the kitten is not a thoroughbred Briton! Maybe because of envy?
Answer: If this stright was born before 2005, then everything is legal. So the kitten is British. After all, the law does not have retroactive force, and it was adopted only in 2005.
7. I would like to know, but the British purple cats should have a big belly or this is bad. Should I go to the vet?
The answer is that the big belly of cats (not only purple) is as bad as people's. If the cat will only eat and sleep on the bed, then it will soon come obesity. We must limit it in food and play more games.
8. The husband brought the kitten, said that he was from british cat (he saw a cat, but his mother does not). His head is somehow big. Tell me, please, the husband says that this is a sign of the breed, and I doubt it is so or not?
Answer: In appearance, the kitten can be similar to the British: they are characterized by a large round head, small ears, thick paws, short plush coat. However, if there are no documents on the kitten, it is considered to be mongrel. It could be an unplanned mating with a mongrel. Grow out of it can do anything.
9. To my cat 1 year 1 month, not sterilized, I feed only with food Proplan, yes she is not anything but food. What worries me is that it is too small for a British woman. By what age does the cat reach its real size, maturity? And different in size a cat gave birth to a cat who did not give birth?
The answer: the size of a cat depends on many factors. Most of all, the origin, the pedigree, how large the parents are. However, in the same litter can be kittens, both large and small. usually the first kittens are larger than the last. By the age of 1,5 the cat reaches the size of an adult animal. After giving birth, a cat can gain weight.
10. Tell me, please, Skotish Straits grow as big as the British, and how do they differ?
Answer: there is no single answer. Strikes can be larger than individual Britons, and may be less. It all depends on the pedigree. Even in one litter can be large kittens and smaller ones. If we take to compare a small kitten from the litter of pure Britons and a large kitten of the straite, then we can make the erroneous conclusion that the straights are larger. However, according to the breed standard, the British must have more strikes.
11. We took from the nursery a sterilized british cat tricolor color with a passport. In the graph, the breed indicates: selkirk-rex. What does it mean?
Answer: one of two things: either they mixed the documents, or you received the Selkirk-rex, and this is another breed. Selkirk-Rex are not British.
12. The cat is 3 months old, on the breast it already has a plush short coat, and closer to the tail is too long, but the undercoat is plush. Will she have a wool for plush? If so, how soon?
The answer: a children's fur coat changes on adult till half a year. After 4 months it is already clear which cat will have hair. If there is a dense undercoat and a long awn, this can change. However, if the nape is short and the tail is long, lying, then most likely it will be so.
13. The kitten on the back foot has an underdeveloped "finger, with a fingernail" (fifth), should it be removed? Thank you in advance.
Answer: Polydactyly is a tribal marriage. Such a cat should not be allowed to breed and at the exhibition he will receive a disqualification. If he lives at home, then surgery is not needed, this is not affected by health.
14. The kitten is 3 months old, it weighs about 1 kg, is it normal weight? Parents are British and Scot, is it possible to breed? Very aggressive in games, trying to bite your hand, sometimes it's very difficult to calm down what to do?
Answer: you have a kitten - a straight, i.e. Scottish prickly. In the future, it can be knit with the Scottish lop-eared cats. The standard is easier for the British. Character - this is a purely individual characteristic. Just you got such a copy.
15. If both parents were lop-eared and in the litter it turned out to be prickly, what should be in the passport?
Answer: two lop-eared knit is prohibited, because can in most cases show defects in the osseous system. Straight-eared scottish cats are denoted by SFS71.
