White Cats and Deafness: Understanding the Risks and Care

White cats with striking blue eyes often captivate us with their elegance, but many owners wonder if these beautiful felines are prone to deafness. The relationship between white coats, eye colour, and deafness risk is complex but important to understand for responsible cat care.

Genetic research reveals that the dominant white (W locus) gene, responsible for white coat colour in cats, can affect the inner ear development and lead to congenital deafness. However, not all white cats— even those with blue eyes—are deaf. The risk is higher, particularly with blue or odd-coloured eyes, but about 31% of white cats with blue eyes retain normal hearing. Moreover, white cats with yellow or non-blue eyes have a lower, yet notable, risk of deafness.

The deafness commonly occurs on the same side as the blue eye in odd-eyed cats, often affecting just one ear. Understanding these nuances helps owners provide better care, especially since deaf cats live full, happy lives with proper attention and a safe environment.

1. Turkish Angora

The Turkish Angora is an affectionate and intelligent breed admired for its pure white coat and sometimes odd-coloured eyes. These cats are playful and social, known to be good with children and other pets. However, if a Turkish Angora has a blue eye, there is a chance of deafness in the ear on that side.

2. American Shorthair

Known for their gentle nature and robust health, American Shorthair cats come in various colours. If they have a white coat with blue eyes, there is an increased possibility of deafness, although this does not prevent them from living vibrant and healthy lives.

3. The Exotic

The Exotic breed resembles the Persian but is easier to groom, sporting a short, dense coat. White-coated Exotics may have blue eyes and be prone to deafness, but with attentive owners, these cats thrive beautifully.

4. Cornish Rex

The Cornish Rex has a unique wavy coat and a playful, energetic personality. Some white Cornish Rex cats with blue eyes may be deaf, but their joyful character remains unaffected by hearing loss.

5. Devon Rex

Devon Rex cats have large ears and captivating expressions. They enjoy solitary time but are curious and interactive with their owners. Deafness can occur in white and blue-eyed individuals, yet these cats still lead mischievous and fulfilling lives.

6. The Maine Coon

The mighty Maine Coon is celebrated for its size and affectionate nature. While less commonly white, some Maine Coons can have white coats and blue eyes, putting them at risk for deafness, which requires special care to keep them safe in busy environments.

Can You Test for Deafness in Cats?

Yes, cats can be tested for hearing using the BAER (brainstem auditory evoked response) test. This veterinary procedure measures electrical activity in the hearing pathways. If you suspect your white cat has hearing difficulties, discuss this test with your vet to confirm deafness and understand the best care approach.

How to Care for White Cats and Deaf Cats

White cats require extra protection from sun exposure to prevent sunburn and related skin cancers, especially on pale ears and noses. During summer, limit their time outside during peak sunlight hours or provide shade and protective measures.

Deaf cats need a safe, secure environment to protect them from dangers like traffic or predators since they cannot hear approaching threats. Keeping deaf cats indoors or on a lead during outdoor times is advisable. Provide visual cues, gentle handling, and patience for the best quality of life for deaf cats.

Why Are White Cats Deaf?

Quick Answer: Deafness in white cats is linked to a genetic mutation at the dominant white (W locus) gene affecting melanocytes, which impacts pigmentation and inner ear development. Cats with blue eyes have a higher risk, but not all white cats are deaf.

The white coat gene disrupts melanocytes, cells responsible for both pigmentation and proper inner ear function. This disruption causes sensorineural deafness in many white cats with blue eyes. However, the genetic effect varies, so some white cats, even with blue eyes, maintain normal hearing. The deafness risk is less in white cats with non-blue eyes.

Responsible breeders aim to manage this inheritance to reduce deafness risk. Understanding the gene and testing cats helps ensure ethical breeding and better pet health outcomes.

Summary and Next Steps

White cats with blue or odd eyes are more prone to deafness due to a genetic mutation, but many are not affected. Regular hearing testing, sun protection, and safe management of deaf cats ensure these beautiful felines live happy and healthy lives. If considering a white cat breed, always seek reputable breeders who prioritise health and responsible practices.

Knowing the specific needs of white and deaf cats enriches the joy of ownership and helps these special pets thrive in loving homes.
