Progressive retinal atrophy has no treatment - your cat will go blind. PRA is an inherited disease where the retina degenerates over months to years. You'll typically notice when your cat bumps into furniture in dim light or has dilated pupils. By then, a lot of vision is already gone. Diagnosis costs $200-$500; no medicine can stop it.

What Causes PRA in Cats
Inherited disease where retinal photoreceptors degenerate. Rod cells (night vision) fail first, then cone cells (color and detail). Different mutations affect different breeds - rdAc is common in Abyssinians and Somalis. Autosomal recessive: both parents must carry the gene. Inherited, progressive, incurable

Symptoms

What to Watch For
Night blindness comes first - hesitation in dim light, bumping into objects, reluctance to jump in dark rooms. Pupils become progressively dilated with increased eye shine in photos. Eventually complete blindness in both eyes. Some cats compensate so well that you may not notice for months. Earliest sign: night blindness

Diagnosis

$200-$500
Ophthalmologist exam reveals retinal thinning, blood vessel attenuation, and increased reflectivity. Electroretinography (ERG) detects PRA before symptoms by measuring retinal cell response. DNA testing ($40-$100) confirms the mutation. Both eyes always affected. Average: $200-$500

Treatment

None Available
No treatment, surgery, or medication can stop PRA. Antioxidant supplements lack proven benefit. Focus on home adaptation: keep furniture positioned consistently, use scent markers, avoid rearranging rooms, and block hazards. No cure - focus on adaptation

Total Cost

$200-$500
Diagnosis only. There's no ongoing treatment cost beyond routine vet visits. DNA testing for breeding cats adds $40-$100. $200-$500 for complete diagnosis.

Certain Breeds

Higher Risk
Abyssinian and Somali cats have the highest rates (rdAc mutation). Persian and Siamese are also affected. DNA testing can identify carriers before breeding.

Progressive

Leads to Blindness
Timeline varies by breed and mutation. Some cats lose vision over 1-2 years, others over 5+. Complete blindness is inevitable, but cats adapt remarkably well.

Prevention
DNA test breeding cats before mating. Never breed two carriers together. Responsible breeding is the only way to eliminate PRA from affected lines.

Insurance Traps

With no treatment available, insurance value for PRA is limited - but diagnosis coverage still matters.

PRA Coverage Basics

Chronic condition
Most policies cover diagnostic workup - ophthalmologist exams and electroretinography. The standard 14-day illness waiting period applies. Since there's no treatment, ongoing coverage provides limited benefit. The main value is covering the specialist diagnosis: $200-$500.

The Hereditary Exclusion Problem

Exclusion
PRA is hereditary and some budget policies exclude hereditary conditions entirely. If you own an Abyssinian, Somali, or Persian, verify your policy covers inherited diseases. Even diagnostic costs may be denied if your insurer excludes hereditary conditions. Premium plans typically cover the diagnosis.

Limited Financial Impact

Deductible
PRA has low total cost: $200-$500 since there's no treatment. Insurance value is more peace of mind than protection. Your deductible alone may exceed total diagnosis cost. PRA is one condition where insurance doesn't change your finances much.

Secondary Complications Coverage

Coverage
Blind cats can get hurt in falls, collisions, and accidents. Insurance covering accident-related injuries becomes more valuable after vision loss. Some cats develop anxiety or behavioral changes requiring veterinary care. These secondary issues are typically covered separately.

Common Questions

Real answers about costs, treatment, and insurance coverage.

What is progressive retinal atrophy in cats?
PRA is a group of inherited diseases where retinal photoreceptors slowly deteriorate. Rod cells (night vision) degenerate first, followed by cone cells (color and detail). This causes progressive, irreversible blindness in both eyes. Different gene mutations cause PRA in different breeds.
Can PRA in cats be treated or cured?
No - no treatment, surgery, or medication can stop PRA. Gene therapy research is ongoing but not yet available clinically. Retinal cells cannot regenerate once lost. All the focus is on adapting your home to your cat's fading sight and eventual blindness.
How quickly does a cat go blind from PRA?
Timeline varies by breed and mutation. In Abyssinians (rdAc mutation), vision loss typically progresses over 2-5 years with complete blindness by age 5-7. Early night blindness can last months to years before daytime vision fails. Each cat progresses at its own pace.
What are the first signs of PRA in cats?
Hesitation or clumsiness in dim light - bumping into objects, reluctance to navigate at night. Pupils become permanently dilated; increased eye shine in photos is another early clue. Many owners mistake these changes for aging rather than vision loss.
Which cat breeds are most affected by PRA?
Abyssinians and Somalis have the highest prevalence (rdAc mutation). Persians and Siamese are affected by different PRA mutations. DNA tests identify rdAc carriers. Responsible breeders test all breeding cats and avoid mating two carriers.
Can a blind cat live a normal life?
Yes - blind cats adapt remarkably well, especially with gradual vision loss. They rely on whiskers, hearing, smell, and spatial memory. Keep furniture positioned consistently, use scent markers near hazards, and block stairways. Most play, navigate confidently, and live full lives.
Is there a DNA test for PRA in cats?
Yes - DNA tests exist for several PRA mutations, including rdAc in Abyssinians and Somalis. Cost: $40-$100. Results: clear, carrier, or affected. Carriers show no symptoms but pass the gene - testing is the only way to eliminate PRA from bloodlines.
Does pet insurance cover PRA diagnosis in cats?
Most comprehensive policies cover diagnostic workup - ophthalmologist exams and electroretinography. Since PRA has no treatment, the main cost is the $200-$500 diagnosis. Budget policies that exclude hereditary conditions deny even diagnostic costs. Ensure your policy covers inherited diseases if you own an at-risk breed.

Then came the shock. August 2026, I'm sitting on a bench outside a veterinary clinic in Brno. After his first epileptic seizure. Alf, healthy until recently, has just been diagnosed with a tumor in his belly and one in his head. I look at my own realvetcost.com, and it's one of the three most common conditions in Boxers.

I don't want to see the prognosis, but it's clear. How did it end?
