Hepatic Lipidosis in Cats: Causes Symptoms and Treatment Options

Understanding Hepatic Lipidosis in Cats: Symptoms, Causes, and Diagnosis

Have you noticed that your cat is losing weight, barely eating, and looking sickly with a yellowish tint on its skin, gums, and eyes? These signs could be pointing to hepatic lipidosis, a serious liver condition that affects between 0.5 and 2 percent of cats, often leading to life-threatening complications.

In this article, well take a closer look at the defining features of hepatic lipidosis, its possible causes, and how vets diagnose the condition to provide the best treatment plan for your furry friend. What is Hepatic Lipidosis?

Hepatic lipidosis (HL), also referred to as fatty liver disease, is a reversible condition wherein the liver accumulates an excessive amount of triglycerides, a type of fat, which impairs its normal function. The excess fat deposits can cause structural damage, inflammation, and oxidative stress within the liver cells, leading to a range of clinical signs such as anorexia, lethargy, vomiting, and jaundice.

HL can occur in any breed, age, or gender of cats, but it’s often common in middle-aged, overweight, and inactive cats or those with concurrent illnesses.

Signs and Symptoms of Hepatic Lipidosis

The clinical presentation of hepatic lipidosis can vary depending on the severity and duration of the condition. Some cats may exhibit mild signs initially, while others may show sudden and severe symptoms.

The primary symptoms of hepatic lipidosis include:

– Poor appetite and weight loss: A cat with HL will lose interest in food, leading to weight loss, malnutrition, and muscle wasting. – Jaundice: A yellow discoloration of the skin, mucous membranes, and whites of the eye, caused by the buildup of bilirubin, a pigment in the liver.

– Vomiting: The accumulation of toxins and inflammation within the liver can cause nausea and vomiting. – Lethargy: Due to the decreased energy reserves, a cat with HL will appear subdued, lethargic, and unresponsive.

– Diarrhea and constipation: Changes in bowel movements can occur due to the breakdown of liver metabolism and related complications. – Abnormal bleeding: Vitamin K deficiency and the liver’s inability to produce clotting factors can lead to excessive bleeding in cats.

Causes of Hepatic Lipidosis

HL can arise due to various factors that alter the normal metabolism, distribution, and utilization of fat in the liver. Some causes include:

– Inflammatory Bowel Disease (IBD): Chronic inflammation of the intestines can impair nutrient absorption, leading to malnutrition, and fat accumulation in the liver.

– Liver Disease: Any underlying liver disease such as hepatitis, cirrhosis, or cholangitis can trigger the accumulation of fat in the liver. – Cancer: A malignancy such as lymphoma can lead to HL by disrupting the liver function or impairing nutrient metabolism.

– Pancreatitis: Inflammation of the pancreas can cause enzymatic imbalances, leading to the buildup of fats in the liver. – Environmental Changes: Stress, anxiety, and changes in diet or routine can affect a cat’s appetite, leading to starvation and HL.

– Idiopathic: In some cases, the exact cause of HL remains unknown.

Diagnosis of Hepatic Lipidosis

Diagnosing HL involves a range of tests that help the vet investigate the underlying cause, assess the liver function, and monitor the cats overall health status. The following diagnostic tests are commonly used:

– Bloodwork: A complete blood count (CBC) and serum biochemistry analysis can help identify abnormalities in the blood cells and liver enzymes.

– Urinalysis: A urinalysis can provide clues about the cats kidney function and metabolic status. – Abdominal Ultrasound: An abdominal ultrasound can show the size, shape, and texture of the liver, enabling the vet to assess the degree of fat accumulation and rule out other diseases.

– Liver Cell Sample: A liver biopsy or aspirate can provide a more comprehensive assessment of the liver’s architecture, inflammation, and fat accumulation.

Treatment of Fatty Liver Disease in Cats

Managing HL can be challenging due to the cat’s compromised liver function, nausea, and aversion to food. The treatment plan typically involves addressing the underlying cause, providing nutritional support, and administering supportive care.

Some treatment options include:

Feeding Tube Options

When a cat with HL is not eating, it may be necessary to supplement its caloric needs through a feeding tube. The options include:

– Nasogastric tubes: These tubes are placed through the nose and into the stomach, allowing for liquid food administration.

– Esophagostomy tubes: These tubes are surgically implanted through the neck and into the esophagus, enabling food intake. – Force-feeding: This involves the manual administration of a high-calorie liquid food through a syringe.

Reintroducing Food

The reintroduction of food to a cat with HL must be done gradually to avoid refeeding syndrome, which is a potentially fatal complication that can occur when the body suddenly gets a large quantity of nutrients after a prolonged period of starvation.

Nutritional Supplements and Medications

The following nutritional supplements and medications have been shown to have a beneficial effect on cats with HL:

– B vitamins: These vitamins help support liver function by aiding in the conversion of nutrients and preventing oxidative stress. – Vitamin K: This vitamin helps improve blood clotting, reducing the risk of bleeding.

– Vitamin E: This vitamin helps reduce inflammation and oxidative stress. – S-adenosylmethionine (SAMe): This compound helps improve liver cell health, reduce inflammation, and promote antioxidant activity.

– L-carnitine: This amino acid helps improve fat utilization and energy production. – Milk Thistle (Silybum marianum): This herb contains flavonoids that help reduce inflammation and oxidative stress in the liver.

– Silybin and ursodiol: These medications help improve liver function, reduce fatty acid production, and aid in the excretion of bile salts.


Hepatic Lipidosis is a severe condition that requires prompt intervention to prevent life-threatening complications. If you notice any of these signs in your cat, it’s essential to visit a vet immediately to get a proper diagnosis and treatment plan.

By understanding the causes, symptoms, and treatment options of HL, you can give your feline companion the best possible care, improving its prognosis, and enhancing its quality of life. Recovery and Management for Hepatic Lipidosis in Cats: Hospitalization, Continuing Care, Prognosis, and Survival Rate

Cats with hepatic lipidosis require intensive care and monitoring in the hospital setting to stabilize their health and prevent complications.

Once the cat’s condition improves, it may be discharged, but will still require ongoing care at home. Additionally, the prognosis and survival rate for cats with hepatic lipidosis can vary, depending on a variety of factors, including the severity of the disease and the presence of underlying health problems.

Hospitalization and Monitoring for Cats with Hepatic Lipidosis

Cats with hepatic lipidosis need to be hospitalized initially to receive intensive care that includes nutritional support, fluid therapy, and medication for managing symptoms. The veterinary staff monitors the cat’s weight, hydration status, laboratory values, and other vital signs closely to assess the response to treatment and adjust it as needed.

Bloodwork is often performed routinely to monitor progress and evaluate liver function. As the cat stabilizes, the frequency of these tests will gradually decrease.

Continuing Recovery at Home for Cats with Hepatic Lipidosis

Once the cat is stable, it can be discharged home for continuing recovery, but will still require ongoing care, including feeding tube maintenance, medication administration, and monitoring for signs of complications, such as vomiting, diarrhea, or dehydration. The feeding tube will require periodic flushing to avoid blockages and maintain good hygiene.

As the cat’s appetite improves, the frequency of tube feedings can be gradually reduced, and it may be possible to start offering food by mouth. In addition to nutritional support, cats with hepatic lipidosis may receive medications to support liver function, reduce inflammation, and manage symptoms.

It’s essential to administer these medications as prescribed and monitor the cat for any adverse effects.

Prognosis and Survival Rate for Cats with Hepatic Lipidosis

The prognosis for cats with hepatic lipidosis varies, depending on the severity of the disease, how quickly treatment is initiated, and the presence of underlying health problems. With aggressive treatment and management, many cats can recover fully from hepatic lipidosis.

However, some cats may have underlying conditions that adversely affect their prognosis, such as cancer, organ failure, or immune-mediated diseases. The survival rate for cats with hepatic lipidosis can also vary depending on several factors.

In general, cats with mild to moderate hepatic lipidosis have a good prognosis, with a survival rate of around 80-90% with appropriate treatment and management. However, cats with severe hepatic lipidosis or underlying health problems may have a lower survival rate.

Some studies suggest that cats with hepatic lipidosis that receive aggressive treatment early in the course of the disease have better outcomes than those treated later. Additionally, cats with hepatic lipidosis may be more susceptible to developing other liver diseases or complications later in life, such as bile duct obstruction or liver cirrhosis.

Therefore, it’s essential to monitor the cat’s liver health regularly, even after recovery, to detect any potential problems early.


Hepatic lipidosis is a severe liver condition that requires prompt intervention and aggressive treatment to achieve a good prognosis and enhance the cat’s quality of life. While hospitalized, continued monitoring and adjustment of treatment is necessary until the cat stabilizes.

Once at home, ongoing care that includes feeding tube maintenance, medication administration, and monitoring for signs of complications is crucial for a successful outcome. The prognosis and survival rate for cats with hepatic lipidosis may vary depending on the severity of the disease, presence of underlying health problems, and timely intervention and management.

Therapy and preventive measures must be taken to ensure the cat’s liver health remains stable and does not involve any additional problems later in life. Hepatic lipidosis in cats, commonly known as fatty liver disease, is a severe condition that needs prompt treatment and continuing care to achieve a good prognosis.

The disease’s symptoms and causes can be diverse and varied, and the cat may require hospitalization and immediate interventions upon diagnosis. Although recovery can be possible, ongoing care, including feeding tube maintenance, medication administration, and monitoring for signs of complications, is essential.

Cats with underlying health problems or severe hepatic lipidosis may have a lower survival rate and require more aggressive treatment. Overall, hepatic lipidosis is a potentially life-threatening condition, and cat owners must be mindful of its signs and seek veterinary care immediately.
