Yellow skin, eyes, or ears with fever, vomiting, and anorexia signal cat hepatitis and jaundice. Causes include poor food, pesticides, and human drugs. Treat within a 'golden 14 days' with a vet-guided liver supplement and a light diet.

1 Cat Hepatitis and Jaundice

I. Symptoms of cat hepatitis

If you notice the following signs in your cat, take them seriously:

1. Poor appetite—no interest even with food offered; or wants to eat but loses interest at the sight of it, leading to rapid weight loss and dark urine.

2. Even a little eaten comes back up, usually yellow water or foam.

3. Low spirits, withdrawn, interested in nothing.

4. Dislikes the belly being touched, likely from liver pain.

5. High fever, dry nose, very hot ears, weakness.

6. After three days of anorexia, the inner eyelids, skin, nose, and ears gradually turn yellow—jaundice.

If several signs appear together, hepatitis is all but certain.

You may wonder how a cat gets hepatitis for no reason. What causes it?

1. Too much low-quality cat food.

2. Accidental pesticide—poor-quality ear-mite or flea products.

3. Owners giving human antibiotics or hormone drugs.

4. Liver-cell damage from bacteria or parasites.

If hepatitis does appear, what can you do to help? Here are some measures:

There is a ‘golden 14 days’ for cat hepatitis—systematic treatment within 14 days.

For hepatitis or liver disease, a bile-acid liver supplement helps the patient: it counters fatty liver and gallstones, detoxifies and protects the liver, promotes bile and complement-protein synthesis, and works well for hepatitis, jaundice, ascites, and liver injury. Use once daily at 1 tablet per 5 kg body weight, under veterinary guidance. During treatment keep the diet light and ensure normal eating and nutrition.

Tip: If you’re unsure of the diagnosis, don’t medicate the cat yourself, and never use human drugs—they may backfire!
