We love our cats. They provide us comfort, joy, and occasionally frustration, but our furry friends are an indelible part of our lives that could never be replaced. They count on us for food, care, and protection. Cherishing our cats is more than play time and cuddles—we need to show we care by safeguarding their health. By keeping up with vaccines and checkups, we can take our responsibility as pet owners seriously.
Heart problems in animals are all too common, more so than pet owners realize. If left undiagnosed or untreated, your cat can face significant health challenges. We’ve put this guide together to help you recognize the signs of heart disease in cats, understand when you need to take your cat to a cardiologist, and how to manage their health after a diagnosis.

Your cat’s regular veterinarian is your first line of defense. Paoli Vetcare has decades of experience identifying heart disease. Routine exams and regular checkups are the best way to detect subtle clues, such as heart murmurs or irregular heartbeats, prompting further investigation, diagnosis, and treatment.
If your veterinarian detects an issue, they may refer you to a specialist in feline cardiology. Veterinary cardiologists are specialized veterinarians who focus exclusively on the diagnosis and treatment of heart diseases in animals. They undergo years of training after veterinary school to receive a board certification in cardiology. This experience, coupled with advanced diagnostic tools and technology, allows them to pinpoint and diagnose specific issues that general practitioners aren’t equipped to find.
Early intervention is the best way to treat your cat if they show signs of heart disease. Cat cardiologists can provide veterinary services and life-saving treatments that ensure your pet stays healthy, even after a serious diagnosis.
Why Your Cat Might Need a Veterinary Cardiologist
In most cases, you need to take your cat to a vet cardiologist because your primary veterinarian referred you. Primary care vets are trained to treat many different feline diseases and conditions, but specialists have advanced training in cardiovascular conditions.
Cat cardiologists can diagnose and treat specific conditions, such as Hypertrophic cardiomyopathy (the most common), restrictive cardiomyopathy, and, less commonly, dilated cardiomyopathy. Your cat may show symptoms like breathing difficulty, increased respiratory rate, open-mouth breathing, and exercise intolerance. This leads to appetite loss, rapid breathing, lethargy, paralysis, pain, and collapse.
They can treat hypertension, and vet cardiologists have access to sophisticated diagnoses, utilizing highly specialized equipment which includes electrocardiography (ECG) and digital thoracic radiography. Tailored treatments allow cat cardiologists to improve your furry friend’s health and well-being, which initially begins with you. The better communication between you and the vet, including home observation and bringing them in for their regular checkups.
Speak with your cat’s primary care veterinarian today and book now if you suspect that your cat may have cardiovascular issues. Early diagnosis and preventative care give the cardiologist more time to observe and treat diseases.
Signs Your Cat Might Need a Heart Checkup
Feline heart disease symptoms can be subtle, and easy to miss. Cats rarely show obvious distress, and can instinctively hide their issues from their owners. Observant cat owners must look for small changes in behavior or physical condition and pay attention to any and all health changes that happen over time.
In an emergency, your cat may experience increased resting respiratory rate, open-mouth breathing, or sudden limb weakness and pain. These are signs to seek out immediate veterinary care. Some cats with HCM are asymptomatic, and screenings help find murmurs, gallops, and arrhythmias. Your veterinarian will take blood pressure tests and echocardiography, especially if your cat is an at-risk breed.
Rapid or Labored Breathing
An increased resting breathing rate, labored or open‑mouth breathing, and effortful breathing may indicate fluid in or around the lungs and possible congestive heart failure. Seek veterinary care immediately.
Lethargy or Decreased Activity
Is your cat sleeping more than usual? A typically active cat may start to avoid play, decrease engagement, and become more lethargic because of reduced oxygen circulation or cardiac fatigue.
Sudden Collapse or Fainting
Collapse or fainting spells may signal serious arrhythmias or structural heart problems. Loss of consciousness should be treated as a medical emergency—if your cat suddenly passes out, or spends an increased amount of time asleep, you need to take them in for veterinary evaluation.
Weight Loss or Reduced Appetite
Heart disease can cause fatigue and nausea, which may rob your cat of their appetite, and cause gradual weight loss. When combined with other sudden symptoms, like fainting spells or increased lethargy, this could point to an underlying heart issue that requires veterinary attention.
Heart Murmur
Heart murmurs are unusual sounds made by blood flow into the heart. While heart murmurs can be harmless, they also may indicate a cardiovascular problem. They’re usually discovered during routine veterinary checkups, and your cat’s veterinarian can consider them as part of a cardiovascular issue. Not all murmurs are dangerous, and only a veterinary cardiologist can fully evaluate their case and severity.
Swollen Abdomen
Congestive heart failure (when the heart cannot pump blood effectively) can cause fluid retention and lead to a visibly bloated or firm belly. If your pet has fluid buildup in their lungs, the vet may need to drain it through thoracocentesis or abdominocentesis procedures. These symptoms can appear as breathing issues or lethargy, but if you notice any major physical changes in your cat, you should call the vet right away.
When To Seek Emergency Care
Go to an emergency clinic immediately if your cat has open‑mouth breathing, a resting breathing rate consistently above 35–40 breaths per minute, sudden hind‑limb weakness/paralysis with vocalization, or collapses.
How do you check respiratory rate at home? Count breaths for 30 seconds while your cat is asleep or resting, multiply by two.
What Happens During a Cardiology Visit?
A visit to the cat cardiologist is straightforward, non-invasive, and focused on getting diagnoses and answers. The appointment typically includes multiple diagnostic steps to provide a complete picture of your cat’s heart health. If you’re worried about the exam, your cat’s primary care veterinarian may be able to offer you some answers to your questions.
Consultation and Physical Exam
First, the veterinarian will discuss your cat’s health history and symptoms, followed by a hands-on exam. The cardiologist will listen to your cat’s heart, evaluate their breathing, and take notes of any visible signs that may point to further testing.
Echocardiogram
A feline echocardiogram is a safe and painless ultrasound of your cat’s heart that allows the specialist to view heart structures in real time. By examining the heart’s physical structure, they can get a better idea of issues and complications.
Echocardiography is the gold standard of diagnosis; ECG for rhythm assessment; thoracic radiographs for pulmonary edema/pleural effusion; Doppler blood pressure measurement; optional NT‑proBNP testing as an adjunctive.
Electrocardiogram
The electrocardiogram (ECG) test measures the heart’s electrical activity, allowing the pet cardiologist to detect abnormal rhythms or arrhythmias and diagnose specific issues affecting the heart.
Chest X-rays
X-rays allow the cardiologist to have a visual approximation of the heart’s size and shape. It also allows them to find fluid in the lungs or chest cavity, further helping their diagnosis. This test complements the echocardiogram results by revealing secondary heart disease effects.
Blood Pressure and Lab Work
Checking blood pressure over time in a laboratory helps assess overall cardiovascular function and stress on your cat’s heart. The veterinary cardiologist may include tests for cardiac biomarkers, organ functions, and other underlying heart conditions. Your cat may need certain medications, including diuretics for fluid, ACE inhibitors to lower blood pressure, or beta-blockers to control heart rate.
Blood pressure is measured in a clinic (often with a Doppler device) to screen for hypertension. Your cardiologist may also recommend blood tests, including cardiac biomarkers such as NT‑proBNP, and organ function panels.
Treatment Options
Feline heart disease can be managed effectively with early intervention and personalized care. Lifestyle changes, veterinary diagnoses, medications, and even surgery can help improve your cat’s health, ensure a better quality of life.
Medications
Treatment is individualized and may include diuretics (e.g., furosemide) for fluid buildup, antithrombotic therapy (e.g., clopidogrel) when clot risk is high, and other medications such as beta‑blockers or ACE inhibitors in select cases. Your cardiologist will tailor therapy based on echocardiographic findings.
First-line medications depend on the stages of the disease. Furosemide is used for signs of congestion, clopidogrel for risk of thromboembolism, and pimobendan for certain stages of heart failure. Beta blockers and ACE inhibitors have selective roles for the heart and kidneys.
Lifestyle Changes
There are many lifestyle changes you can make to improve your cat’s overall health. Adjusting their diet, avoiding overexertion, and managing stress and anxiety can all improve health and should be considered part of treatment.
Fluid Draining
In cases of congestive heart failure, fluid may accumulate around the lungs or in the chest cavity/abdomen. Veterinarians may perform thoracocentesis or abdominocentesis procedures to relieve pressure and improve breathing, ensuring that fluid buildup does not lead to heart failure. This also may be managed with medication.
Procedures such as Thoracocentesis/abdominocentesis relieve effusion (abnormal fluid buildup) and respiratory compromise, but cannot prevent or cure heart failure. These supportive measures are typically paired with medications prescribed by the veterinarian.
Surgery
The veterinary cardiologist may recommend surgical options that are case-specific and might even refer you to specialized centers. While surgery may not be the norm, it can be life-saving when necessary. Your veterinarian will talk you through all your options, including tailored health programs, before recommending surgery.
Advanced Treatments
Advanced treatments, such as heart catheterization, defibrillation, pacemaker placement, and experimental therapies, may be offered in place of other more invasive options. Your veterinary cardiologist will speak with you about all your options and ensure you understand each one in-depth. Pacemakers and other devices are very uncommon for cats and are case-dependent at specialty centers.
Why Early Detection Is Everything
Early detection and preventative care allow for better treatment options, slow down disease progression, and improve quality of life. Because cats often hide their symptoms from their owners, proactive screenings or follow-ups can ensure that subtle signs are noticed by your veterinarian, making all the difference.
Premature heart disease in cats can be detected and diagnosed early by a cardiologist, via full echocardiograms and other specialized technologies. While these tests may be costly, and are reserved for when a cat is showing distress, your veterinarian may recommend them based on signs including arrhythmias and heart murmurs.
It all begins with standard physical exams. Veterinarians have a highly successful history of diagnosing cats with moderate heart disease through regular checkups, and can suggest further treatment via a veterinary cardiologist.
