An enlarged liver in cats, known as hepatomegaly, can be caused by various conditions including liver disease, heart failure, or cancer. Prompt veterinary attention is crucial for an accurate diagnosis and appropriate treatment.

An enlarged liver in cats, also known as hepatomegaly, can be caused by several underlying conditions. It is crucial to understand these causes and their implications to ensure your feline companion receives appropriate care.
One of the most common reasons for an enlarged liver in cats is hepatic lipidosis, a condition where fat accumulates in the liver cells. This often occurs when cats stop eating or significantly reduce their food intake, leading to a breakdown of fat reserves throughout the body. As the liver processes these fats, it can become engorged and enlarged. Hepatic lipidosis is serious and can be life-threatening if left untreated, but with prompt veterinary intervention, including fluid therapy and nutritional support, many cats can recover.
Another possible cause of an enlarged liver in cats is liver disease, which can be either acute or chronic. Inflammation (hepatitis), infection, toxins, and certain medications can all contribute to liver damage. Chronic liver disease may progress slowly over time, leading to scarring and fibrosis that can impair the organ's function. Symptoms of liver disease in cats include loss of appetite, weight loss, vomiting, diarrhea, and jaundice (yellowing of the skin and eyes). Diagnosis typically involves blood tests, ultrasound, and sometimes a liver biopsy to determine the exact cause and severity of the condition.
Infections, such as feline infectious peritonitis (FIP) or bacterial infections, can also lead to an enlarged liver. FIP is a viral disease that affects the lining of the abdominal cavity and internal organs, including the liver. While there is no cure for FIP, supportive care and management of symptoms are essential to maintain the cat's quality of life. Bacterial infections can sometimes spread from other parts of the body to the liver, causing inflammation and enlargement.
Tumors or cancerous growths within the liver can also cause hepatomegaly. These can be either benign (non-cancerous) or malignant (cancerous). Benign tumors may not require immediate treatment unless they cause significant issues, while malignant tumors can spread to other parts of the body and are often treated with surgery, chemotherapy, or radiation therapy.
If you notice any signs that your cat's liver might be enlarged, such as a distended abdomen, loss of appetite, lethargy, or changes in urine color, it is essential to consult with a veterinarian promptly. They can perform a thorough physical examination and order diagnostic tests to determine the underlying cause of the hepatomegaly. Early detection and treatment are critical for managing many of these conditions effectively and improving your cat's prognosis.
