White cats deafness blue eyes

The resulting congenital deafness is noted by 3 to 4 weeks of age, the age at which newborn kittens normally are able to hear. In one 1997 study of white cats, 72% of the animals were found to be totally deaf. Many cats are born with congenital deafness, which causes deafness in the cat as it ages, instead of later on. 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) we find in the last group, those that are white due to the dominant gene w. The chance of deafness is as high as 80% in a white cat with 2 blue eyes. Studies have shown that solid white cats with two blue eyes have 65% to 85% chance of being deaf. The prevalence of deafness is high in cat populations in which the dominant white gene is segregating. The vet saw them with about 3 weeks, they are now about 4. 3 cats don’t have to be completely white to carry the gene that causes deafness. Deafness in white cats at a glance. Domesticated cats with blue eyes and white coats are often completely deaf. In addition, cats with albinism are susceptible to suffering from both deafness and blindness. The white fur and blue eyes both are a consequence of a lack of melanin from pigment cells. The main characteristic of an albino cat is a complete unblemished white coat, blue eyes and pink skin, including the nose, eyelids, ears and paw pads. White kitten with blue eyes are often be associated with blindness and deafness.

The objective of this study was to investigate whether there is a gene that is responsible for deafness as well as for blue eyes and to establish a plausible mode of inheritance. Pointed cats, like siamese, who have a lighter body and darker extremities, always have blue eyes. Deafness is more likely to occur in white cats with blue eyes; So if the cat has blue eyes, it is more likely to be deaf, and if it has only one blue eye, it maybe deaf on only that side, and the cochlea in the ear on the other side will have developed normally. However, there is no need to be feared to bring a cat with blue eyes home because more than 50 percents of cats who are not pure white, their blue eyes are not always related to deafness and blindness. Cats with blue eyes can sometimes have visual or auditory deficiencies. If this is not treated early, cats will not be able to hear as well as they should be able to. And 65 to 85 percent of white cats with two blue eyes were deaf. Cats can be deaf in one or both ears. When the white spot gene affects both eyes the cat will have blue eyes. Congenital sensorineural deafness occurs in domestic cats with a white coat. Some of these breeds only ever have. Deafness can occur in white cats with yellow, green or blue irises, although it is mostly likely in white cats with blue irises. However, the prevalence of white cats does vary in different geographies. A survey of 185 white cats reported the following results:

65% to 85% deafness occurs if a white cat’s eyes are both blue. Indeed, says james flanders, dvm, associate professor of surgery at cornell university’s college of veterinary medicine, “about 80 percent of white. There are other reasons for cats being white, and also other genes which can affect eye colour. Hereditary deafness is a major concern in white cats, and even more so if one or both irises are blue in color. White cats can have blue, gold, green or copper coloured odd eyes. Albino cats are also incredibly sensitive to prolonged and intense sun exposure. However, things are not quite that simple and clear cut. Deafness is far more common in white cats than in those with other coat colors. Cats that have the dominant white gene can sometimes, but not always, have blue eyes. 1 the same gene that causes a white coat in cats can also sometimes result in deafness. Some cats are born deaf, and the disability cannot be corrected. Meantime, the same defect often also affects a cell layer of the inner ear that is essential for hearing. Disorders of cats with blue eyes. Mine is not fully white, it has some pigmentation on the tail, although it does have both eyes blue. There is a gene/gene complex which causes white coat, blue eyes and deafness, but not all cats get their white coat and blue eyes from that particular gene, so not all white cats will be deaf.

Due to an anomaly in their genetic makeup, for example, white cats with blue eyes are at greatest risk for congenital deafness. 40% chance of hearing loss if a cat has only one blue eye. 40 percent of white cats with one blue eye were deaf; When the gene affects only one eye the cat will have odd eyes. It's believed that the ear closest to the oddly colored eye (or both ears if both eyes are uniquely colored) will be the ear with deafness. Eye color in white cats also relates to the potential for deafness. A cat with a gene with white spots (like the tuxedo cat) can have blue eyes or in some cases odd eyes. It is a congenital deafness caused by a degeneration of the inner ear. If a white cat has only one blue eye, there’s about 40% chance of hearing loss. Black and white cats with blue eyes have a much more common type of hearing and vision problem that may be related to their eye color. From what i read, pure white cats, specially with blue eyes are very likely to be deaf, amost 80%. White cats are also genetically more predisposed to being deaf. 2 cats with white coats and blue eyes are highly likely to be deaf in one or both ears. White cats need to inherit a particular gene or gene complex to be diagnosed deaf. This masking gene is also sometimes responsible for blue eyes in white cats.
