Hepatic Lipidosis in Cats: Welfare Emergency Management

Key Welfare Considerations

• Hepatic lipidosis results from fat mobilisation to the liver during anorexia — cats are uniquely susceptible.
• Any cause of reduced food intake for 3+ days can trigger welfare hepatic lipidosis in cats.
• Clinical welfare signs include jaundice, lethargy, vomiting, and progressive hepatic encephalopathy.
• Obese cats have higher welfare risk — excess fat mobilisation overwhelms hepatic processing capacity.
• Primary hepatic lipidosis has no underlying cause — stress, food change, or environmental disruption triggers it.
• Secondary hepatic lipidosis complicates pancreatitis, IBD, diabetes, and other welfare underlying diseases.
• Nutritional support through oesophageal or gastrostomy tube feeding is the welfare cornerstone of treatment.
• Target calorie intake of 60-70 kcal/kg/day is required for welfare recovery from hepatic lipidosis.
• Feeding must resume gradually — refeeding syndrome welfare risk from rapid phosphate and potassium shifts.
• Cobalamin (B12) supplementation is welfare-important — deficiency compounds hepatic metabolism impairment.
• S-adenosylmethionine (SAMe) provides hepatocyte welfare protection during lipidosis recovery.
• Silymarin (milk thistle) provides antioxidant welfare hepatic support during recovery.
• N-acetylcysteine supports glutathione welfare antioxidant pathways during hepatic recovery.
• Recovery from hepatic lipidosis with aggressive welfare support typically takes 3-6 weeks.
• Prevention through preventing prolonged anorexia in any cat is the most important welfare measure.
