What breeds of cats can be deaf? - briefly
Certain breeds of cats are known for their increased likelihood of being deaf. These include white cats with blue eyes, such as those from the British Shorthair and Scottish Fold breeds, due to a genetic link between coat color and hearing impairment. Additionally, the Siamese breed can also be prone to deafness in one or both ears.
What breeds of cats can be deaf? - in detail
Deafness in cats is primarily associated with coat color, specifically the white gene (W), which is responsible for the development of the inner ear structures during embryogenesis. This gene can cause congenital deafness in cats, particularly those with predominantly white fur or blue eyes. While deafness can occur in any breed, certain breeds are more predisposed due to selective breeding practices that favor specific coat colors and patterns.
The White Cat Syndrome (WCS) is the most common cause of inherited deafness in cats, affecting both ears (bilateral deafness). This condition is prevalent in breeds with a high incidence of white fur and blue eyes. The following breeds are among those most commonly associated with deafness:
-
White Cat Syndrome-Prone Breeds: These breeds have a significant percentage of cats affected by WCS due to the genetic predisposition for white fur and blue eyes.
- American White: Nearly all American Whites are deaf, with some exceptions having residual hearing.
- Turkish Angora: A notable proportion of Turkish Angoras, especially those with predominantly white coats, can be deaf.
- Japanese Bobtail: Deafness is common among Japanese Bobtails with predominantly white fur.
-
Breeds with High Incidence of White Fur and Blue Eyes: These breeds are not exclusively prone to WCS but have a higher incidence of deaf cats due to their coat color genetics.
- Siamese: While not all Siamese cats are deaf, those with predominantly white fur or blue eyes can be affected.
- Birman: Birmans, particularly those with significant white patches and blue eyes, may experience deafness.
- Ragdoll: Some Ragdolls, especially those with white mitted or bicolor patterns, can be deaf.
-
Other Breeds with Increased Prevalence of Deafness: These breeds do not necessarily have a high incidence of white fur and blue eyes but may still have an increased prevalence of deafness due to genetic factors.
- Domestic Shorthair/Longhair: Mixed-breed cats, particularly those with predominantly white coats or blue eyes, can be affected by WCS.
- Persian: Some Persians, especially those with specific coat patterns, may have a higher incidence of deafness.
It is important to note that not all cats with white fur or blue eyes are deaf, and not all deaf cats have white fur or blue eyes. Deafness can also occur due to other factors such as age-related hearing loss, exposure to loud noises, or certain medications. However, the association between coat color and deafness in cats is well-established, and breeders should be aware of the potential risks when selecting for specific coat colors and patterns.
If you suspect your cat may be deaf, it is crucial to consult with a veterinarian who can perform appropriate tests to confirm the diagnosis. Early detection and understanding of your cat's sensory limitations can significantly improve their quality of life through proper care and adaptation strategies.
