1. 🧬 What Is Feline Hepatitis?

In cats, 'hepatitis' often refers to **cholangiohepatitis**—inflammation of the liver, bile ducts, and gallbladder—as well as isolated cholangitis

• These conditions overlap with pancreatitis and IBD, often called “triaditis” :contentReference[oaicite:3]{index=3}.
• Inflammation blocks bile flow, causing digestive issues, liver injury, and secondary fatty liver (hepatic lipidosis) and clotting or neurologic concerns :contentReference[oaicite:4]{index=4}.

2. ⚠️ Common Causes & Risk Factors

• Bacterial or fungal infections—especially common in triaditis cases :contentReference[oaicite:5]{index=5}.
• Viral agents (FIP, FeLV, FIV) can inflame the liver :contentReference[oaicite:6]{index=6}.
• Parasites (liver flukes, Toxoplasma), toxins, medications, or metabolic/genetic disorders :contentReference[oaicite:7]{index=7}.
• Underlying conditions like pancreatitis, IBD, gallstones or immune disease are often part of the puzzle :contentReference[oaicite:8]{index=8}.

3. 🩺 Recognizing Warning Signs

• Vomiting, diarrhea, weight loss, and reduced appetite are common early symptoms :contentReference[oaicite:9]{index=9}.
• Lethargy, fever, abdominal pain, dark urine, pale stools, and jaundice may also appear :contentReference[oaicite:10]{index=10}.
• Neurologic signs (confusion, seizures) or clotting issues can happen in severe or chronic cases :contentReference[oaicite:11]{index=11}.

4. 🔍 Diagnostic Process

• Physical exam checks eyes, coat, abdomen; blood panel for liver enzymes, bilirubin, clotting, FIV/FeLV, pancreatitis :contentReference[oaicite:12]{index=12}.
• Imaging (X‑rays, ultrasound) assess organ size, fluid, gallbladder; bile aspirate may test for infection :contentReference[oaicite:13]{index=13}.
• Additional testing: bile culture, liver biopsy, or genetic/metabolic evaluations provide definitive diagnosis :contentReference[oaicite:14]{index=14}.

5. 💉 Treating Hepatitis in Cats

a. Hospital & Supportive Care

• Hospitalization with IV fluids, feeding tubes, pain control, and anti-nausea meds is often necessary :contentReference[oaicite:15]{index=15}.
• Nutrition support to prevent hepatic lipidosis—therapeutic diets or tube feeding are used :contentReference[oaicite:16]{index=16}.

b. Medications & Supplements

• Long-term antibiotics (e.g., Clavamox, Baytril, metronidazole) to address infection :contentReference[oaicite:17]{index=17}.
• Anti-inflammatories—steroids (prednisolone) and carefully chosen NSAIDs to reduce liver inflammation :contentReference[oaicite:18]{index=18}.
• Drugs supporting bile flow (ursodiol), appetite stimulants, and liver protectants (SAMe, silymarin, vitamin E) are commonly used :contentReference[oaicite:19]{index=19}.

c. Surgical or Specialist Treatment

• Surgery may be required to remove gallstones or blocked bile ducts, often by a specialist :contentReference[oaicite:20]{index=20}.

6. 🍽️ Nutrition & Home Strategy

• High-calorie, easily digestible diets supporting liver function are key :contentReference[oaicite:21]{index=21}.
• Feed small frequent meals, warmed for palatability; prescription therapeutic liver diets ideal :contentReference[oaicite:22]{index=22}.
• Monitor hydration—ensure clean water, consider wet food or water fountains.
• Home medication compliance is essential—track meds, appointments, and appetite/activity changes.

7. 📅 Prognosis & Ongoing Care

• If caught early and treated thoroughly, many cats recover and can live normal lives :contentReference[oaicite:23]{index=23}.
• Regular vet checks, blood tests, and imaging monitor liver function and detect relapse :contentReference[oaicite:24]{index=24}.
• Some cats need lifelong medications; severe cases or complications may require palliation or euthanasia :contentReference[oaicite:25]{index=25}.

8. 🩺 Vet’s Final Takeaways

• Feline hepatitis is a complex liver/gallbladder inflammatory health threat—often part of triaditis.
• Early recognition and aggressive vet care significantly improve recovery.
• A comprehensive plan—hospitalization, meds, supportive diet, and monitoring—is essential.
• Close follow-up and nutritional support are key to avoiding hepatic lipidosis and relapse.
