Hi there, I’m sorry to hear about your kitties. Heart failure in cats can be challenging and understandably concerning. The life expectancy depends on various factors, including the underlying cause, how advanced the condition is at diagnosis, and how well they respond to treatment.
In cats, heart failure is commonly due to cardiomyopathy, a disease affecting the heart muscle. Symptoms often include lethargy, breathing difficulties, decreased appetite, or coughing. Sometimes, a cat with heart failure may have good days mixed with not-so-good ones.
While we can’t predict exactly how long a cat will live with heart failure, many can still have a decent quality of life with medication, dietary changes, and regular vet check-ups. At home, ensure they have a stress-free environment and a warm, comfortable place to rest. Keep their food and water easily accessible, and watch for any changes in their behavior or appetite.
It's crucial to stay alert for signs like rapid breathing, increased effort to breathe, bluish gums, or sudden hind leg weakness, as these could indicate an emergency.
I'm here to support you in navigating this journey. It might be beneficial to discuss your cats' specific conditions in a video consult with a vet on Dial A Vet to get personalized advice and develop a care plan tailored to their needs.
