Bengal Health Issues Calgary: HCM, PRA-b, PK-Def, FIP

Hypertrophic cardiomyopathy is a disease in which the wall of the left ventricle (the main pumping chamber of the heart) thickens abnormally. As the muscle thickens, the chamber holds less blood and the heart has to work harder. In some cats this stays mild for years. In others it progresses to congestive heart failure or to a sudden blood clot (thromboembolism) that often paralyses the rear legs. In the worst cases, sudden cardiac death is the first sign.

Bengals are over-represented for HCM in the published feline cardiology literature, and specific prevalence figures vary between studies. That breed over-representation is the basis for the annual echocardiogram screening protocol the cardiology community recommends, regardless of how the cat presents at home.

No DNA test for Bengal HCM

This is the part Calgary Bengal owners most often misunderstand. Ragdolls have a DNA test (the HCM2 mutation). Maine Coons have a DNA test (the MyBPC3 mutation). Bengals do not. As of 2026 there is no commercially available DNA test for the Bengal form of HCM. The only screening tool is the echocardiogram.

That changes the conversation with breeders. An ethical Bengal breeder will tell you that their breeding cats receive annual echocardiograms from a veterinary cardiologist, and they will be able to produce the reports. A breeder who claims their lines are HCM-clear because of DNA testing is either mistaken or selling a different breed's test. For Calgary rescue Bengals (or Bengal mixes), parental history is unknown, so the practical screening tool is the same: annual echocardiogram from age 2 by a Calgary veterinary cardiologist.

The echocardiogram protocol

Diagnosis starts with a routine veterinary exam where the vet listens to the heart with a stethoscope. A heart murmur is not itself a diagnosis of HCM (many cats have benign or stress-related murmurs), but it is a reason for further workup. The definitive diagnostic is an echocardiogram performed by a veterinary cardiologist.

In Calgary, this means a referral from your general-practice vet to Western Veterinary Specialist & Emergency Centre, which houses the city's main feline cardiology service. Expect to pay roughly 400 to 600 dollars per scan. The recommended cadence for an asymptomatic Bengal is annual from age 2 onwards.

Walking into a specialty centre without a referral is uncommon and may not be possible at all clinics. Build the relationship with one general-practice clinic first, and ask them to refer you in for the screening echocardiogram when your Bengal reaches the recommended age.

HCM symptoms to watch for at home

HCM can be silent for years. When symptoms appear, the most common ones are:

• Increased respiratory rate at rest (a sleeping cat should breathe 15 to 30 times per minute; persistently faster is a vet call)
• Lethargy or hiding when the cat is usually social (a notable change for a Bengal, given the breed's typical high activity level)
• Decreased appetite
• Sudden weakness, fainting, or collapse
• Sudden rear-leg paralysis (this can indicate a saddle thrombus, a blood clot that lodges where the aorta divides; it is a same-day Calgary 24-hour emergency)
• Open-mouth breathing or laboured breathing (always urgent in a cat)

Any of the above warrants a call to your veterinarian. Open-mouth breathing in a cat is an emergency. Drive to a Calgary 24-hour emergency vet rather than wait until morning.

Treatment and lifetime cost

Management of HCM is entirely vet-directed. There are several treatment categories in feline cardiology, including medications that reduce heart muscle workload and prevent blood clot formation. What is appropriate depends on the stage of disease, the individual cat, and other health factors. No medication, dosage, or treatment protocol is recommended on this page. Your veterinary cardiologist makes those decisions in partnership with you.

Lifetime cost of HCM management varies widely. A Bengal diagnosed early with mild disease might cost 3,000 to 5,000 dollars in cumulative monitoring and medication over a decade. A cat with progressive disease, recurring imaging, and emergency interventions can easily reach 10,000 dollars or more. This is the strongest single argument for pet insurance enrolled before age 2.

PRA-b is the Bengal-specific variant of progressive retinal atrophy, an inherited form of feline blindness. It is autosomal recessive, which means a kitten needs two copies of the mutated gene (one from each parent) to develop the condition. Carriers (cats with one copy) have normal vision but can pass the gene to their kittens.

Vision loss typically begins around 7 weeks of age and progresses to severe impairment by about 2 years. The change is gradual, which is why cats adapt so well. A Bengal that loses vision over its first two years learns its home environment in stages, and by the time blindness is complete, the cat navigates by smell, hearing, and whisker-based spatial sense.

DNA testing is straightforward:

• Available through the UC Davis Veterinary Genetics Laboratory and Wisdom Panel
• Cheek swab kit, returned by mail
• Cost: roughly 60 to 100 dollars per test
• Results in 2 to 4 weeks

Ethical breeders test breeding pairs. Acceptable pairings are N/N (clear) bred to N/N or N/PRA-b (carrier). Pairing two carriers (PRA-b/N x PRA-b/N) has a 25 percent chance of producing affected kittens and should not happen. Pairing two affected cats (PRA-b/PRA-b x PRA-b/PRA-b) guarantees affected kittens and is not ethical breeding.

For a Calgary Bengal adopter, the conversation with a breeder includes asking to see PRA-b test certificates for both parents. For a Calgary rescue Bengal, the test is optional but informative; if you suspect an unusual sensitivity to dim light in a young Bengal, a DNA test confirms or rules out PRA-b without invasive procedures.

No treatment exists for PRA-b. Management is environmental: keep furniture stable, do not rearrange rooms, keep food and litter boxes in fixed locations, and supervise any unfamiliar-space access. A blind Bengal in a stable indoor home lives a normal feline life and a normal feline lifespan.

Pyruvate kinase deficiency is an inherited hemolytic anemia documented in Bengals (and several other cat breeds, including Abyssinians and Somalis). It is autosomal recessive, like PRA-b, so a kitten needs two copies to develop the condition.

PK-Def causes red blood cells to break down prematurely, which produces episodic anemia. Affected cats may show lethargy, pale gums, jaundice (yellowing of the gums and the whites of the eyes), and exercise intolerance. Onset is variable: some affected cats present in young adulthood, others in middle age. The condition is manageable with supportive care and is rarely immediately fatal, but it does shorten lifespan in some affected cats.

DNA testing is available through the UC Davis Veterinary Genetics Laboratory for about 60 to 100 dollars. Ethical breeders test breeding cats and follow the same pairing logic as PRA-b: clear-to-clear or clear-to-carrier is acceptable, carrier-to-carrier is not.

For Calgary adopters, asking a breeder to produce PK-Def test certificates on both parents is standard. For a Calgary rescue Bengal showing unexplained pale gums or recurring episodes of lethargy, the test is one of the workup options a vet may discuss. Management of PK-Def is vet-directed and depends on the severity in the individual cat.

FIP is caused by a mutation of the common feline coronavirus inside an individual cat. The coronavirus itself is widespread and usually harmless, but in a small proportion of cats it mutates into the form that causes FIP. The disease has two main presentations: wet (effusive, with fluid accumulating in the abdomen or chest) and dry (granulomatous, with inflammatory lesions in organs and sometimes neurological signs).

Bengals are over-represented in FIP literature, though specific incidence figures are not well-published. The likely reason is that Bengals more often come from multi-cat cattery environments where coronavirus exposure is higher. Single-cat households with limited cat-to-cat contact see less FIP than catteries or multi-cat rescues. The Cornell Feline Health Center is the citation-grade source for general FIP information.

GS-441524 access in Calgary

GS-441524 is the antiviral that has changed FIP outcomes. It is now accessible in Canada through veterinary prescription via compounding pharmacies. The treatment course runs about 84 days, typically as a daily oral or injectable dose. Cost is a meaningful financial commitment that varies widely by cat weight, treatment form (oral vs injectable), and compounding pharmacy. Discuss specifics with your Calgary veterinarian and confirm pricing before starting treatment.

The access pathway works like this: a primary Calgary vet identifies suspected FIP, refers to a specialist for diagnostic confirmation (often at Western Veterinary Specialist & Emergency Centre), the diagnosis is confirmed, the prescription is written, and a compounding pharmacy fills the prescription. Calgary owners report that the diagnosis-to-treatment timeline is typically 1 to 3 weeks, which matters because faster intervention produces better outcomes.

Signs of FIP in a young Bengal include persistent fever that does not respond to antibiotics, weight loss, decreased appetite, lethargy, abdominal swelling (wet form), jaundice, or neurological signs (head tilt, seizures, gait change). Any of these signs in a young cat warrants a same-week vet appointment.

Bengals tolerate standard feline anaesthetic protocols. Unlike Maine Coons and Ragdolls, where breed-elevated HCM is more formally documented as an anaesthesia caution, no Bengal-specific anaesthesia warning is published. Routine spay or neuter at a young age, dental cleanings, and most elective surgeries are low-risk procedures.

The practical caveat is HCM-driven. Any cat aged 4 or older benefits from a pre-anaesthetic echocardiogram before elective surgery, because Bengals carry elevated HCM risk. If an annual screening echocardiogram is already part of your Bengal's care plan, that report is what your vet uses. If not, a pre-operative echocardiogram referral is worth discussing with your Calgary veterinarian before elective procedures in middle-aged or older Bengals.

Standard pre-operative bloodwork and pulse oximetry monitoring during surgery are the rest of the protocol. For young Bengals under 4 with no history of heart issues, standard protocols are used. Discuss any specific concerns with your Calgary veterinarian before the procedure.

Beyond the four headline conditions, several less common issues are worth keeping on the radar:

• Urinary tract issues (FLUTD, bladder stones). Moderate Bengal predisposition. A wet-food-heavy diet helps. A male cat that is straining and unable to urinate is a same-day Calgary 24-hour emergency.
• Patellar luxation. The kneecap slipping out of its groove. Occasional in Bengals, more common in some toy dog breeds. Mild cases are managed conservatively; severe cases may need surgical correction.
• Hip dysplasia. Rare in Bengals but documented. Symptoms can mimic other joint conditions and are diagnosed by radiograph.
• Distal neuropathy. Rare. A degenerative nerve condition presenting with hindlimb weakness in young adult Bengals. Bloodwork and neurological exam guide diagnosis.
• Flat-chested kitten syndrome. Rare but documented in active Bengal lines. Usually identified in young kittens and managed with veterinary care. Adults are not typically affected.
• Dental disease. Not breed-specific, but worth flagging. Bengals benefit from annual dental exams and periodic professional cleanings under anaesthesia (which is where the pre-anaesthetic echocardiogram becomes relevant for cats aged 4 and over).

None of these conditions on its own justifies a different adoption decision. Bengals as a breed are fundamentally healthy, with several documented elevated risks that are manageable with proactive care. Annual exams catch most issues early.

Bengals are pet-insurance-positive because the breed's elevated health risks can produce real lifetime cost. A few directional figures to plan around (these are 2026 Calgary estimates, not quotes from any specific provider):

• HCM workup and lifetime management can run 3,000 to 10,000 dollars depending on stage and treatment approach
• Annual cardiology echocardiogram at a Calgary specialty centre: typically 400 to 600 dollars
• GS-441524 FIP treatment full course: a meaningful financial commitment that varies by cat weight, treatment form, and compounding pharmacy. Confirm pricing with your Calgary veterinarian before starting treatment.
• Emergency visit for suspected saddle thrombus, urinary blockage, or open-mouth breathing: easily 1,500 to 3,000 dollars for one night

Canadian carriers Bengal owners typically consider include Trupanion, Petsecure, and Pet Plus Us. Monthly premium ranges 50 to 90 dollars depending on age, deductible, and coverage tier. The right policy depends on budget and risk tolerance.

The pre-existing condition rule

Every Canadian pet insurance provider excludes pre-existing conditions. This means anything diagnosed before policy purchase is permanently excluded from coverage, and related conditions are often excluded too. A few examples of how this plays out for Bengals:

• HCM diagnosed at age 4 on a routine echocardiogram, with no prior policy in place: HCM permanently excluded from any subsequent policy
• A urinary blockage incident at age 2: future FLUTD episodes may be excluded as related
• A heart murmur noted at routine exam but not yet investigated: enrolling immediately may preserve coverage, but providers vary

The clear takeaway: enrol at adoption or by the first vet visit, ideally before age 3. A Bengal kitten enrolled at month 3 with a clean physical exam qualifies for the broadest coverage available. The cost of waiting is not the premiums you save, it is the coverage you lose on the conditions you are most likely to need.

Read the fine print on hereditary-condition coverage in particular, since some lower-tier policies exclude HCM as a breed-typical condition. The full-coverage tier is usually worth the premium difference for a Bengal.

Cardiology, internal medicine, and FIP treatment for Bengals usually involve referral from your general-practice vet to a specialty centre. The Calgary clinic that handles most Bengal-relevant specialty work:

Your relationship with one general-practice clinic matters more than picking the “best” one. A vet who knows your cat's baseline catches subtle changes that a one-time specialist visit misses. The specialist comes in when something specific is needed: the annual HCM echocardiogram, a suspected FIP workup, or an emergency.

For routine spay, neuter, vaccines, and wellness care, any Calgary general-practice veterinary clinic that you trust is appropriate. The Bengal-specific layer (echocardiograms, DNA test interpretation, FIP prescription) is where specialty referral comes in.

The realistic budget for a healthy Calgary Bengal, to discuss with your veterinarian and adjust based on the individual cat:

The HCM and FIP rows are why pet insurance matters. Without coverage, a single major diagnosis can run five figures. With coverage purchased before diagnosis, the same diagnosis may cost a few thousand in deductibles and co-insurance. The math is the same conversation as the cost of waiting on insurance: every month of delay is a month of risk.

Bengals run larger than average domestic cats, so plan for gear that fits a 10 to 15 pound active adult. The basics to keep in one place:

• Cat carrier sized for a Bengal. Minimum 24 by 16 inches, hard-sided, rated for car travel. Expect 80 to 150 dollars for a quality carrier. A too-small carrier in a stressed cat is a same-day vet problem.
• Printed copy of your pet insurance policy. Including policy number and after-hours contact.
• Recent photo of your cat. For identification if a carrier opens during transport, or for posting if the cat is lost.
• Vaccination records. Most Calgary emergency clinics ask for current vaccine status on intake.
• Written list of known sensitivities. Any prior reactions to medications, food intolerances, or chronic conditions.
• After-hours vet phone number. Western Veterinary Specialist & Emergency Centre operates 24-hour emergency. Save the number in your phone and post it on the fridge.
• Latest annual echocardiogram report. Especially important for Bengals aged 2 and over. If your cat is brought in for breathing changes or collapse, the existing cardiology report saves time.

Keep the kit in one accessible place. A stressed owner during a same-day vet trip should not be searching through filing cabinets for paperwork.

Lifespan is one of the most-asked Bengal questions on rescue forums, and the answer cuts through a lot of breed mythology:

• Average Bengal lifespan is 12 to 16 years
• Healthy Bengals routinely reach the upper end of that range
• HCM is the leading cause of premature death in the breed
• Indoor-only lifestyle, weight management, dental care, and annual screening pull individual cats toward the longer end
• Outdoor-access Bengals (where local bylaws and the cat's temperament permit) face the same outdoor risks as any cat: vehicles, predators, infectious disease, theft

The Bengals we see live longest share a pattern: their owners picked one Calgary veterinary clinic and stayed with it, did not skip annual exams, started the cardiology screening protocol at age 2, watched for breathing and litter box changes at home, and had pet insurance in place before any diagnosis. None of that requires a panicked or anxious owner. It requires consistency. The owner who shows up for annual exams in good years is the same owner ready for the cardiology referral when a murmur shows up at age 6.
