Heart Disease in Cats: Preventable Causes

October 14, 2025

According to our veterinary team at Northlands Cat & Rabbit Care Clinic, cat heart disease typically affects around 10-15% of cats, more so as they age. The risk of this disease can vary based on several factors, some preventable including diet, stress and overall health.

In this article, our vets explain these factors and the signs that cat owners in Northamptonshire should look out for.

Early diagnosis is crucial to getting your cat the treatment they need so don’t hesitate to book an appointment with our vets if you spot any worrying signs.

Preventable causes of heart disease in cats

Heart disease in cats can be serious, but the good news is that some causes are preventable with responsible care and monitoring. While certain conditions like congenital defects can’t be avoided, many cases are linked to lifestyle and health factors that cat owners can manage.

Obesity

Our vets in Northampton explain that one of the most common preventable contributors is obesity. Overweight cats are at higher risk of developing high blood pressure and heart problems. Ensuring your cat maintains a healthy weight through a balanced diet and regular exercise is essential.

Poor diet

Poor diet can also play a role. Diets high in salt or lacking in essential nutrients may increase the strain on your cat’s heart over time. Our vets suggest feeding a high-quality, life stage appropriate, complete diet to help maintain overall cardiovascular health.

Untreated hypertension

Untreated hypertension (high blood pressure) is another preventable factor. Cats with kidney disease, hyperthyroidism, or obesity are more prone to high blood pressure, which can damage the heart if left unchecked. Regular vet check-ups at Northlands Cat & Rabbit Care Clinic can help identify these conditions early and allow for timely treatment.

Dental disease

Dental disease might seem unrelated, but infections in the mouth can release bacteria into the bloodstream, affecting the heart and other organs. Keeping your cat’s teeth healthy and addressing dental issues promptly supports long-term heart health.

Stress

Finally, excessive stress can contribute to cardiovascular strain. Our Northampton vets share that providing a calm, enriching environment, regular play and safe spaces for retreat can help reduce anxiety-related strain on the heart.

By managing weight, diet, blood pressure, dental health, and stress, the risk of preventable heart disease can be significantly reduced – all things we can support you with at Northlands Cat & Rabbit Care Clinic. Regular veterinary check-ups remain key to spotting early signs and protecting your feline friend’s heart for years to come.

Signs of heart disease in cats

Heart disease in cats can be challenging to detect, especially in its early stages, as cats are known for hiding signs of illness. We therefore recommend regular check-ups for cats of all ages (but especially cats over 5 years and those pre-disposed) at our Northampton practice – early detection and intervention can lead to better disease management and improved quality of life.

There are however some symptoms of feline heart disease that you may be able to spot at home. Take a look at Northlands Cat & Rabbit Care Clinic’s fact sheet: Symptoms of Heart Problems in Cats.

If you notice any signs or have concerns about your cat’s heart health, it’s crucial to contact us and book a check-up promptly.
