Cat Hepatic Lipidosis: Prevention and Emergency Care

Feline hepatic lipidosis is a life-threatening liver disease triggered by prolonged anorexia, most common in obese cats during stress.

Key Facts

Hepatic lipidosis (fatty liver disease) occurs when cats mobilize fat faster than the liver can process it
Obese cats are significantly more susceptible due to larger fat reserves mobilized during anorexia
Any cause of anorexia lasting more than 3-5 days can trigger hepatic lipidosis in susceptible cats
Clinical signs include jaundice, vomiting, drooling, and progressive neurological signs
Diagnosis uses biochemistry showing elevated liver enzymes, bilirubin, and ultrasound of the liver
Treatment requires aggressive nutritional support via feeding tube until the cat resumes voluntary eating
Prognosis is good with early treatment but mortality increases dramatically with delayed diagnosis

Welfare Considerations

Hepatic lipidosis causes jaundice, nausea, and progressive neurological deterioration as liver function fails. Affected cats are profoundly unwell with significant suffering from multiple organ effects. The condition is entirely preventable by ensuring cats eat every 24-48 hours and by addressing obesity to reduce fat mobilization risk. Early recognition and aggressive nutritional support via feeding tube enables recovery with good prognosis when initiated before severe liver failure.

What You Can Do

Never allow cats to fast voluntarily for more than 24-48 hours without veterinary consultation
Seek emergency veterinary evaluation for jaundiced or profoundly anorexic cats immediately
Implement weight reduction in obese cats gradually (no more than 1-2% body weight per week) to prevent lipidosis
Address the underlying cause of anorexia promptly in obese cats to prevent lipidosis development
Learn to check for jaundice by examining gums and whites of eyes in anorexic cats
Maintain cats on appropriate diets to prevent obesity that creates hepatic lipidosis vulnerability
