Not all white cats are deaf. Unless both ears are affected, cats may never show any signs of hearing loss.
Once again, the brilliant scientist was right since between 56% and 90% of cats (according to different studies) with white coat and blue eye color are deaf from one or both ears.
Are all white cats with blue eyes deaf. How do cats get blue eyes? And 65 to 85 percent of white cats with two blue eyes were deaf. For each type of white cat, there needs to be specific genetic combinations.
65% to 85% deafness occurs if a white cat’s eyes are both blue. There is a relationship between white cats with blue eyes and genetic deafness, though not all cats with this combination will be affected. This occurs during fetal development, after conception, the embryo splits into three primitive germ layers:
In cats, congenital deafness is seen almost exclusively in white coated individuals. About half of all white cats are deaf, and those numbers increase in cats with blue eyes, with deafness often found on the same side as the blue eye — left blue eye, deaf in left ear; Accordingly, white or lightly colored cats often have light eyes.
The deaf ear is usually on the same side as the blue eye. In one 1997 study of white cats, 72% of the animals were found to be totally deaf. White cats with blue eyes are deaf even the ones with one blue eye and another different color eye are deaf in one ear.
While 40% of white cats with blue eyes are deaf it still means 60% are not, so you should not assume a cat is deaf just because their eyes are blue and their coat is white. Cats with just one deaf ear may appear perfectly normal, and their problem may never become known to their human companions. An estimated 40 percent of white cats with blue eyes are deaf, which is high.
While there is no truth that all white cats with blue eyes are deaf, science has proven that the number of deaf cats with at least one blue eye, is high. Albino cats (red eyes due to c gene or blue due to k gene) totally or partially white cats (due to the s gene) all white cats (due to the dominant w gene) Many (but not all) white cats are deaf.
White cats can have blue, gold, green or copper coloured odd eyes. Blue eyed white cats do have a higher risk of being deaf than other cats, but they're not all deaf. But they are just like any normal cat and if you have the time then there are people that can help you train them.
White color of the coat occurs in cats in the following three ways: Why are white cats with blue eyes usually deaf? I’ve also seen white cats with green eyes or gold eyes who are also deaf.
Of white cats with one blue eye, about 40 percent are deaf in at least one ear. While this could be true to some extent, it doesn’t make black and white cats that much different from other cats of the same breed. Some of these cats are deaf in only one ear.
And, if the white cat has a different eye color for each eye (heterochromia. Cats, however, often have eyes that look very pale blue, pink, or red. Is that true, and why?
Albino cats are not linked to deafness. Around 40% of cats with white fur and blue eyes are deaf. White cats with blue eyes often suffer from a genetic defect that causes their cochlea, a vital organ within the inner ear, to degenerate shortly after birth.white cats with eyes of other colours can usually hear.
The roll of the genetic dice that produces a white. Felines with a single blue eye are often deaf in one hear (usually the ear on the same side as their blue eye), while two blue eyes make an ivory cat likely to suffer total deafness in both ears. Deafness can occur in white cats with yellow, green or blue irises, although it is mostly likely in white cats with blue irises.
No, not all pure white cats with blue eyes are deaf, however:. 40 percent of white cats with one blue eye were deaf; Coat color and an aspect of the cat’s personality or another aspect of anatomy can be linked if the gene that dictates the cat’s colour and a gene which affects the way the brain develops are situated close together on the same chromosome.
It sounds like yours clearly are not totally deaf, since you have plenty of examples of them responding to sound. White cats commonly have blue eyes or reddish eyes in the case of albinos. The deafness is caused by degeneration of the auditory apparatus of the inner ear and may affect one ear (unilateral) or both (bilateral).
People ask why white cats with blue eyes are deaf. It has to do with a genetic trait in all white cats. White cats with blue eyes had a high probability.
However, some are just partially deaf, or just deaf in one ear. Domesticated cats with blue eyes and white coats are often completely deaf. Two blue eyes, completely deaf.
However, the prevalence of white cats does vary in different geographies. My veterinarian said white cats are often deaf. Eye color in white cats also relates to the potential for deafness.
A white cat with one blue eye has a 39% chance of at least partial deafness, and a white cat with two blue eyes may have a 65% chance. Interestingly, if a white cat with one blue eye is deaf in only one ear, that ear will invariably be on the same side of the head as the blue eye. You could get her hearing tested, it's called a baer test.
A pure white cat with blue eyes has an 85 percent chance of some degree of deafness. The reason, as you may have guessed, is heredity: Still, look at it this way:
<br /> the genes for deafness and pigmentation are allelic to each other and are expressed in equal proportion.<br /> the gene for pigmentation masks the gene for hearing.<br /> a single gene is responsible for pigmentation and hearing.<br /> nextreset Continue to 3 of 8 below. They have approximately a 20 percent chance of being deaf to some degree.
You can help a deaf cat lead a happy, full life by keeping it protected indoors and learning to use visual signals and vibrations to communicate. 40% chance of hearing loss if a cat has only one blue eye. Certainly, if you have or see a white cat with blue eyes, i’d check for deafness, but don’t expect it because it’s.
The gene responsible is pleiotropic. If 40 percent of these cats are deaf, it means the majority (60 percent) can hear. To see if a cat is deaf, try standing a few metres away from them and clapping your hands loudly.
Blue eyed cats are more often deaf than white cats with other coloured eyes. Not all of these cats are deaf (see part 2 of this short article).
