Enlarged liver in cats, also known as hepatomegaly, is a condition in which the liver becomes swollen. It is often a result of an underlying condition that needs to be diagnosed and treated by a veterinarian. In this article, we will discuss the symptoms, causes, and treatments for this condition to help you understand and care for your cat’s health.

Symptoms of Enlarged Liver in Cats

The condition produces a range of symptoms that you should be aware of. Some of the most common symptoms include:

1. Swollen abdomen: One of the noticeable signs of an enlarged liver in cats is a distended abdomen. You may notice your cat’s belly appearing larger than usual.

2. Loss of appetite: Cats with an enlarged liver may experience a lack of interest in food. They may refuse to eat or show a decreased appetite.

3. Lethargy: Cats may become weak and lethargic when their liver is enlarged. They may show a lack of energy and interest in normal activities.

4. Increased water consumption: Your cat may start drinking more water than usual. This can be a result of the liver’s impaired function.

5. Frequent urination: Cats with an enlarged liver may urinate more frequently than normal. This can be a sign of the liver’s inability to properly process waste products.

6. Weight loss: Unexplained weight loss can occur in cats with an enlarged liver. This can be due to a decrease in appetite and the liver’s compromised ability to process nutrients.

7. Jaundice: In severe cases, cats may develop jaundice, which is characterized by yellowing of the skin, gums, and eyes. This occurs when the liver is unable to process bilirubin properly.

Causes of Enlarged Liver in Cats

The main cause of an enlarged liver in cats is an underlying condition that needs attention. Some common underlying causes include:

1. Liver disease: Various liver diseases can lead to hepatomegaly in cats. These include hepatitis, cholangitis, and liver tumors.

2. Infections: Bacterial, viral, or fungal infections can affect the liver and result in its enlargement.

3. Toxins: Exposure to certain toxins, such as drugs, chemicals, or poisonous plants, can damage the liver and cause swelling.

4. Heart disease: Some heart conditions can lead to congestion in the liver, causing it to enlarge.

5. Metabolic disorders: Certain metabolic disorders, such as diabetes or hyperthyroidism, can affect liver function and lead to enlargement.

Treatment for Enlarged Liver in Cats

When you suspect that your cat may have an enlarged liver, it is essential to consult a veterinarian for a proper diagnosis and treatment plan. Here’s what to expect during the veterinary visit:

1. Medical history and physical examination: Your vet will inquire about your cat’s symptoms and medical history. This may include breed-specific risks and any previous health issues.

2. Diagnostic tests: Blood and urine tests will be conducted to assess liver function and identify potential underlying causes. Abdominal X-rays and ultrasounds may also be used to confirm the condition and evaluate the liver’s size and structure.

3. Treatment plan: The treatment for an enlarged liver in cats would depend on the underlying cause. In severe cases, hospitalization may be required. Antibiotics may be prescribed to treat any infections present.

4. Medication adherence: It is important to follow your vet’s prescribed medication instructions carefully. Administer the correct dosage and complete the full course of medicine to ensure effective treatment.

5. Diet and rest: Your cat may need a period of cage rest to aid in recovery. Additionally, your vet may recommend a dietary change. A low-sodium, high-protein diet can support liver health. Your vet will help you formulate a safe and appropriate diet plan for your cat.


Enlarged liver in cats is a condition that requires proper diagnosis and treatment by a veterinarian. Recognizing the symptoms, understanding the underlying causes, and following the treatment plan are essential for your cat’s well-being.
