Just like your heart, your cat’s heart is responsible for pumping blood to different parts of the body, helping organs and muscles function properly and stay healthy. It needs to be in good condition to do its job effectively! That’s why it is important for you to understand your cat’s heart health. Taking your cat to the veterinarian for regular checkups is the first step.

During your cat’s examination, the veterinarian will look for signs of heart disease. This can be a challenge as many cats that have heart disease may not show any signs or symptoms. In fact, cats can have heart disease for years before you notice something is wrong. So here’s what you need to know.

Risks and Symptoms
Cats are most commonly affected by a type of heart disease known as hypertrophic cardiomyopathy, in which the walls of the heart thicken and do not pump blood effectively.This can lead to heart failure. This type of heart disease can be found in cats of any age and because it is more common among some cat breeds than others, there may be a genetic predisposition. Breeds most commonly affected include:

Keep in mind that it’s easy to confuse the signs of heart disease with the signs of aging. That’s why it’s important to keep an eye on your cat and call your veterinarian if you notice that your cat:Cat Laying Down

  • Is tired or lethargic and doesn’t want to exercise or play

If your veterinarian suspects that your cat has heart disease, he or she will perform a complete physical exam and pay close attention to the heart to find clues as to whether your pet has any heart-related problems. Heart disease doesn’t always cause murmurs, so some additional tests may be performed:

  • X-rays to check for abnormalities in the heart or lungs
  • NTproBNP Test, a blood test similar to those used to detect heart disease in humans
  • A blood pressure test
  • An electrocardiograph (ECG) to evaluate the electrical activity of the heart
  • An echocardiogram (ultrasound) to measure heart structure and function
