Senior Bengal Health Screening: HCM, PRA & Joints
Screening a senior Bengal cat: hypertrophic cardiomyopathy, PRA-b vision loss, pyruvate kinase deficiency anemia, and patellar luxation joint disease.
The Bengal is a striking, athletic breed with a wild look and a personality to match: energetic, clever, and endlessly busy. That vitality is one reason owners love them, but the Bengal also carries a handful of breed-associated health risks that deserve attention as the cat ages. Unlike breeds defined by a single signature disease, the Bengal benefits from a broader screening approach covering the heart, the eyes, the blood, and the joints.
This guide walks through the four areas worth screening in a senior Bengal: hypertrophic cardiomyopathy (HCM), progressive retinal atrophy (PRA-b), pyruvate kinase deficiency (PK deficiency), and patellar luxation with its arthritis. It complements our broader senior Bengal care guide. Everything here is educational and meant to support, not replace, the care of your veterinarian.

Hypertrophic Cardiomyopathy in the Bengal
HCM is the most common heart disease in cats, and the Bengal is among the breeds in which it appears. In HCM, the muscular wall of the heart's main pumping chamber thickens, so the chamber cannot relax and fill normally. The danger is that it stays silent until a crisis: congestive heart failure, where fluid floods the lungs, or a blood clot called saddle thrombus.
Because a stethoscope misses many cases, the reliable screen is an echocardiogram by a veterinary cardiologist, ideally with periodic rechecks for a senior Bengal. At home, you can track the resting respiratory rate: count breaths while your cat sleeps over 30 seconds and double it, watching for a rate that climbs above 30. Our guides to heart disease and HCM in senior cats and taking your cat's resting respiratory rate cover both in depth.

PRA-b: Inherited Vision Loss
Progressive retinal atrophy of the Bengal type, or PRA-b, is an inherited disease in which the retina's light-sensing cells gradually die, causing slow, progressive blindness. It is recessive, so a cat must inherit two copies of the mutation to be affected, and a straightforward DNA test identifies both carriers and affected cats. Onset is typically in young to middle adulthood, so a senior Bengal may already be living with reduced vision.
There is no cure, but the outlook for quality of life is genuinely good. Cats rely heavily on smell, hearing, and whiskers, and they adapt to gradual vision loss far better than people expect. The key is a stable environment: keep furniture, food, water, and litter boxes in consistent places, avoid startling a blind cat, and use scent and texture cues. Our guide to vision loss in senior cats offers practical home adaptations.

PK Deficiency and Anemia
Pyruvate kinase deficiency is an inherited defect in an enzyme that red blood cells need to function. Without enough of it, red cells break down early, causing anemia that often waxes and wanes. Signs include pale gums, weakness, lethargy, reduced stamina, and sometimes a poor appetite. It is inherited recessively and identified with a DNA test, so many Bengals can be screened before symptoms appear.
Severity varies a great deal. Some affected cats live near-normal lives with mild, intermittent anemia, while others need closer management. The concern in a senior Bengal is that anemia is harder for an aging body to compensate for, especially alongside kidney disease or other conditions that also affect red blood cells. If your Bengal seems unusually tired or its gums look pale, ask your vet to check a blood count. Our guide to anemia in senior cats explains the signs and workup.
Patellar Luxation and Joint Health
The Bengal is prone to patellar luxation, where the kneecap slips out of its normal groove. Mild cases may cause an occasional skip in the step, while more significant luxation destabilizes the joint and accelerates arthritis over the years. Combine that with the breed's love of high-flying leaps, and a senior Bengal's knees and other joints carry real wear.
Watch for the feline signs of joint pain: reluctance to jump to former favorite heights, taking stairs slowly, stiffness after rest, and reduced grooming over the lower back. Protect aging joints by keeping your Bengal lean, offering a daily joint supplement with glucosamine and chondroitin, and adding ramps or steps to high perches so your cat can stay active without painful jumps. Our guide to signs your old cat is in pain helps you read the subtle cues.
Keeping a Senior Bengal Thriving
The thread running through Bengal care is that this is a breed that needs to stay engaged. Adapt enrichment rather than removing it as joints stiffen or vision fades: puzzle feeders, gentler wand play, ramped cat shelves, and window perches. Pair that with the screening above, regular bloodwork, an echocardiogram, genetic testing, and weight control, and you give your athletic senior Bengal the best chance at a long, comfortable, and stimulated life.

Frequently Asked Questions
What are the main genetic health risks in senior Bengals?
The Bengal carries several breed-associated risks worth screening for as it ages: hypertrophic cardiomyopathy (HCM), the most common feline heart disease; progressive retinal atrophy of the Bengal type (PRA-b), an inherited cause of blindness; pyruvate kinase deficiency (PK deficiency), which causes anemia; and patellar luxation, a kneecap problem that contributes to arthritis. Some of these have DNA tests, while others, like HCM, are best screened with imaging. A combination of genetic testing and regular veterinary monitoring covers the breed well.
Should a Bengal be screened for HCM?
Yes. Like several pedigree breeds, the Bengal can develop hypertrophic cardiomyopathy, in which the heart muscle thickens and the chamber cannot fill properly. HCM is usually silent until a crisis such as heart failure or a blood clot, so an echocardiogram by a veterinary cardiologist is the most reliable screen, far more sensitive than a stethoscope. For a senior Bengal, a baseline echo with periodic rechecks, plus blood pressure and thyroid testing, gives the clearest picture of heart health.
What is PRA-b and how is it tested?
Progressive retinal atrophy, Bengal type, is an inherited disease in which the light-sensing cells of the retina gradually die, leading to vision loss and eventually blindness, usually in young to middle-aged adults. It is caused by a recessive mutation, so a cat needs two copies to be affected, and a simple DNA test identifies carriers and affected cats. There is no cure, but cats adapt remarkably well to gradual blindness, and a stable, familiar home environment helps a visually impaired Bengal thrive.
What is PK deficiency in Bengals?
Pyruvate kinase deficiency is an inherited enzyme defect that shortens the lifespan of red blood cells, causing intermittent anemia. Affected cats may show pale gums, weakness, lethargy, and poor stamina, sometimes coming and going over time. It is inherited recessively and detectable with a DNA test. Severity varies widely, and many cats live reasonably normal lives, but a senior Bengal with PK deficiency needs monitoring, because anemia is harder for an aging body to tolerate alongside other conditions.
Do Bengals get joint problems as they age?
They can. The Bengal is prone to patellar luxation, in which the kneecap slips out of its groove, and over years this instability promotes arthritis in the knee. Combined with the breed's athletic, jump-loving lifestyle, joints take real wear. Senior Bengals may become reluctant to make their usual big leaps, hesitate on stairs, or seem stiff after rest. Keeping your cat lean, providing a joint supplement, and adding ramps or steps to favorite high perches all help protect aging joints.
How do I keep a senior Bengal active and enriched?
Bengals are intensely active and intelligent, and that does not switch off with age. A bored senior Bengal can become destructive or stressed, so keep enrichment going at a gentler pace: puzzle feeders, wand-toy play scaled to its mobility, cat shelves with easy ramp access, and window perches for bird-watching. Adapt rather than withdraw activity as joints stiffen or vision fades. Mental and physical engagement supports weight control, joint health, and overall wellbeing in this athletic breed.
Is screening and care for a Bengal expensive?
Several breed risks mean several potential bills: an echocardiogram for HCM, genetic panels for PRA-b and PK deficiency, anemia monitoring, and eventually arthritis or eye care. Individually each is manageable, but together over a Bengal's life they add up, and an HCM crisis can be costly. Because the Bengal carries multiple known, breed-specific risks, this is exactly the situation pet insurance is built for, provided you enroll before any condition is diagnosed and excluded as pre-existing.
