Hypertension occurs when the blood pressure in the arteries gets excessively high, placing additional strain on the cat's heart and blood vessels. Learn about how to prevent them in this article.

Hypertension, also known as high blood pressure, is a common medical condition in cats that can lead to serious health complications if left untreated. This condition occurs when the blood pressure in the arteries becomes too high, putting extra stress on the heart and blood vessels. Cat hypertension is often caused by underlying medical conditions such as kidney disease, hyperthyroidism, or heart disease, but it can also be a side effect of certain medications.

In this article, we will discuss the common complications associated with hypertension in cats, including heart disease, kidney disease, and vision problems, and what you can do to help prevent them.

Some Causes of Hypertension Complications In Cats

  • Kidney disease

  • Hyperthyroidism

  • Cardiac disease

  • Diabetes Mellitus

  • Obesity

  • Chronic Renal Failure

  • Dehydration

  • Adrenal gland disorders

  • Nutritional imbalances

  • Certain medications.

What Complications Can Feline Hypertension Lead To?

Hypertension can cause many complications in cats, including:

  • Retinal detachment: The blood vessels in the eyes can be harmed by high blood pressure, which can result in retinal detachment, which can impair vision or result in blindness.

  • Kidney disease: Hypertension can lead to kidney damage in cats, causing kidney disease, which can lead to decreased kidney function and an increased risk of urinary tract infections.

  • Heart disease: High blood pressure causes the heart to work harder than normal, which results in heart disease, which in turn can result in heart failure, feline arrhythmias, and other heart-related issues.

  • Neurologic disease: Seizures, migraines, and other neurologic issues can result from hypertension damaging the blood arteries in the brain.

  • Abdominal bleeding: Abdominal bleeding can result from high blood pressure damaging the blood vessels in the abdomen.

  • Blood clots: Hypertension can increase the risk of blood clots, which can cause a range of health problems, including stroke, heart attack, and deep vein thrombosis.

Symptoms of Feline Hypertension

Symptoms of feline hypertension can include:

  • Blindness or vision loss: The blood arteries in the eyes can be harmed by high blood pressure, which might result in blindness or visual loss.

  • Seizures: Seizures may result from blood vessel damage from hypertension that affects the brain.

  • Head tilt: High blood pressure can cause damage to the inner ear, leading to a head tilt or unsteady gait.

  • Dilated pupils: High blood pressure can harm the blood vessels in the eyes, causing dilated pupils.

  • Behavioral changes: Changes in behavior, such as increased irritability, restlessness, or hiding, may occur due to the discomfort or pain caused by hypertension.

  • Increased thirst and urination: Hypertension can damage the kidneys, causing increased thirst and urination.

  • Weakness or lethargy: High blood pressure can cause general malaise or weakness.

  • Decreased appetite: Pain or discomfort associated with hypertension may decrease a cat's appetite.

  • Heart murmur: Hypertension can strain the heart, leading to a heart murmur.

  • Nausea or vomiting: Vomiting and nausea may be brought on by the pain or discomfort that high blood pressure causes.


There are various steps involved in the diagnosis of feline hypertension:

  • Physical examination: A veterinarian will perform a thorough physical examination to look for signs of hypertension and any associated health problems.

  • Blood pressure measurement: A cat-specific blood pressure cuff is used to take the patient's blood pressure. Usually, the cat is awake and at ease when this measurement is done.

  • Laboratory tests: In order to assess thyroid, blood glucose, and kidney function, all of which can affect hypertension, blood, and urine tests may be used.

  • Ocular examination: An ophthalmologic examination may be performed to evaluate the health of the blood vessels in the eyes and to look for signs of retinal damage.

  • Imaging studies: Imaging studies, such as an ultrasound or X-rays, may be performed to evaluate the heart and blood vessels.

A veterinarian can identify feline hypertension and the underlying cause, if one is found, based on the results of the physical examination, laboratory testing, and imaging studies.

Treatment Options for Feline Hypertension

There are several possible treatments for feline hypertension. They are:

How To Prevent Hypertension Complications In Cats

To prevent hypertension complications in cats, you should:

  • Monitor blood pressure regularly: Regular blood pressure measurements by a veterinarian can help detect hypertension early and prevent complications from developing.

  • Maintain a healthy weight: Maintaining a healthy weight through proper diet and exercise can help prevent hypertension and its associated complications.

  • Avoid medication-induced hypertension: Some medications can increase blood pressure, so it's important to discuss any medications your cat takes with a veterinarian to determine if they contribute to hypertension.

  • Provide a healthy diet: A healthy, well-balanced diet can help prevent hypertension and the difficulties that come with it.

  • Encourage regular physical activity: Maintaining a healthy weight, enhancing general health, and preventing hypertension may all be achieved with regular exercise. You can engage your cat with toys.

However, to create a preventative strategy suitable for certain cats, you must collaborate closely with a veterinarian. Regular monitoring, lifestyle changes, and effective treatment of underlying conditions can help prevent hypertension and its associated complications in cats.
