Liver Disease in Cats (Hepatic Lipidosis): Recovery from Jaundice & Anorexia
Hepatic lipidosis (fatty liver) in cats: recognizing jaundice, force feeding, and tube feeding recovery guide. Vet-supervised.
The Bottom Line: An Overweight Cat That Stops Eating for 3+ Days Is in Danger
Hepatic lipidosis (fatty liver disease) is a life-threatening condition unique to cats that develops rapidly when an overweight cat stops eating. The body mobilizes stored fat so quickly that the liver becomes overwhelmed — its cells fill with fat globules and begin to shut down.
If your overweight cat has not eaten for three or more days, treat it as an emergency. Without prompt treatment, the fatality rate is high. However, with proper nutritional support, the survival rate exceeds 80%.
Symptoms and How to Spot Jaundice
Early symptoms:
- Loss of appetite lasting three or more days
- Lethargy or listlessness
- Vomiting
Advanced symptoms:
- Jaundice: The whites of the eyes (sclera), the inside of the ears, and the gums take on a yellow tint. The easiest place to spot it is the whites of the eyes
- Drooling (excessive salivation)
- Dehydration
- Muscle wasting (the cat loses muscle mass even though fat reserves remain)
How to check for jaundice at home: In a well-lit room, gently lift your cat's upper eyelid and look at the color of the sclera. If it appears yellowish rather than white, jaundice may be developing and you should see a vet immediately.

Treatment: Nutritional Support Is the Top Priority
The cornerstone of hepatic lipidosis treatment is ensuring adequate caloric intake.
Hospital care:
- IV fluids to correct dehydration and electrolyte imbalances
- Anti-nausea medication
- Placement of a nasoesophageal or esophagostomy feeding tube: The most effective way to deliver nutrition. Liquid food is administered directly through the tube
Tube feeding:
- Daily calorie requirements are divided into 4 to 6 feedings
- High-protein, high-calorie liquid diets are used (such as Royal Canin Recovery Liquid)
- Duration: 2 to 6 weeks is typical, continuing until the cat begins eating on its own
Supportive therapies:
- L-carnitine: Promotes fat metabolism in the liver
- SAMe (S-adenosylmethionine): Protects liver cells from further damage
- Vitamin B complex and vitamin K supplementation
Prevention: Weight Management Is Key
The best ways to prevent hepatic lipidosis are to keep your cat at a healthy weight and to never crash-diet an overweight cat.
Safe weight-loss guidelines:
- Under veterinary supervision, aim for a loss of 1 to 2% of body weight per week
- Never cut food so drastically that the cat refuses to eat
- See our cat obesity guide for a sustainable weight-loss plan
Act quickly if your cat stops eating:
- Even if the cause is stress (a move, a new pet), see the vet if your cat has not eaten for three days
- Try warming wet food to enhance its aroma, or offer a highly palatable option to restart appetite
