Symptoms of Feline Heart Disease: What to Watch For

Heart disease is a significant concern for cats, as research in the United States has shown that even seemingly healthy felines can harbor heart conditions. In fact, as many as 16% of cats may be hiding heart problems, which underscores the alarming reality that many cats could be suffering from heart disease without their owners being aware of it. But does heart disease in cats go unnoticed without any symptoms? The answer is not entirely, though the signs can be subtle and often misinterpreted.

For instance:

1. OpenMouth Breathing

Cats with heart disease may exhibit a clear symptom of openmouth breathing, resembling the panting of dogs with their tongues sticking out. While some may dismiss this as a result of heat, it's crucial to recognize that healthy cats do not breathe this way, even in warm weather. If your cat is panting without exertion, it could indicate severe breathing difficulties, possibly necessitating mouth breathing. Heart failure can lead to such difficulties, and if you notice this behavior, it's vital to take your cat to a veterinarian promptly.

2. Dramatic Abdominal or Chest Movements

In addition to breathing difficulties, cats with heart disease may display noticeable fluctuations in their abdomen or chest. This could be a sign of their struggle to breathe, as they try to endure the discomfort without resorting to openmouth breathing. Such movements are a clear indication of respiratory distress and should prompt an immediate veterinary checkup.

3. Sudden Paralysis of the Rear Legs

Another serious complication of heart disease in cats is sudden paralysis of the hind legs, known as an arterial thrombosis. This occurs when the heart's enlargement, due to worsening heart disease, causes blood to flow unevenly, leading to the formation of abnormal blood clots. If these clots travel to the thigh and block major blood vessels, the leg can become ischemic, leading to loss of sensation and a condition similar to a stroke. When this happens, the chances of successfully treating the heart disease are low, and the cat will experience significant pain. If you notice this symptom, it's imperative to seek veterinary care immediately to secure the best chance for recovery.

4. Sudden Fainting

Some cats with heart disease may experience sudden fainting spells, which are a warning sign that requires immediate veterinary attention. Additionally, heart disease can cause discomfort, leading to a decrease in energy and appetite. If your cat is showing a lack of interest in eating or drinking, or appears listless, it's essential to consult a veterinarian promptly.

These are just some of the common symptoms of heart disease in cats, as highlighted by Oxygen Pet Doctor. As pet owners, it's crucial to be attentive to our feline companions, as this vigilance can help us detect any abnormalities early and take timely preventive or treatment measures.
