Understanding Eye Health in Abyssinian Cats

Quick answer

Abyssinian cats are known for their active and inquisitive nature, but they are prone to a specific form of vision loss known as Progressive Retinal Atrophy. This condition involves a gradual decline in the health of the retina, the light-sensitive tissue at the back of the eye. While there is no cure, early recognition of changes in your cat's behavior, especially in low-light conditions, is the most effective way to manage the impact on their daily life.

Progressive Retinal Atrophy

Progressive Retinal Atrophy is a condition where the retina slowly degenerates over time. This is a recognised tendency in the breed, linked to a specific genetic mutation known as rdAc. Because this is a recognised tendency rather than a proven one in every individual, it is important to observe your cat closely throughout their adult life.

What you will notice at home

The earliest signs of this condition are often subtle and relate to how your cat navigates in the dark. You might notice your cat hesitating before jumping onto familiar furniture at night, or perhaps they seem startled when you approach them in a dim room. In some cases, you may see that your cat's pupils appear wider than usual even when the room is well-lit, as the eyes try to compensate for the loss of sensitivity. As the condition progresses, you may notice your cat bumping into objects or appearing generally less confident when moving through the house after sunset.

What the vet does

When you bring your cat in for an eye concern, your veterinarian will perform a thorough ophthalmic examination. They will use a specialized light source and lens to look directly at the back of the eye, specifically checking the appearance of the retina and the blood vessels that supply it. If they suspect retinal degeneration, they may recommend a referral to a veterinary ophthalmologist. The definitive way to assess retinal function is through an electroretinogram, a test that measures the electrical response of the eye's cells to light. Genetic testing is also available to confirm the presence of the rdAc mutation.

Urgency and management

While this condition is not typically painful, it is progressive, meaning your cat's vision will continue to decline. The urgency lies in helping your cat adapt to their changing environment. Once a diagnosis is reached, the focus shifts to environmental management. Keep furniture in consistent locations, avoid moving litter boxes or food bowls, and use nightlights to help your cat navigate during the evening. How this passes down is not settled, so it is vital to discuss the history of the parents if you are in contact with the breeder.

Routine Health Monitoring

Beyond specific eye concerns, maintaining a general health baseline is essential for the Abyssinian. Create a simple monthly exam routine, or a weekly one for senior cats. This should include checking their body condition score to ensure they are not losing or gaining weight unexpectedly, looking at the color of their gums to ensure they are a healthy pink, and observing their mobility to ensure they are not showing signs of stiffness. Pay attention to their breathing patterns while they are resting and perform a quick check of their skin and coat for any unusual lumps or changes in texture. Keeping a written list of any diet changes or new supplements is a great way to provide your vet with a clear history during your visits.
