Feline hepatic lipidosis.

Hepatic lipidosis occurs when lipid mobilized to the liver exceeds lipid leaving the liver via formation of very-low-density lipoproteins or by oxidation. Hepatic lipidosis in cats is associated with overt liver dysfunction. In affected cats, excess lipid is mobilized to the liver because of starvation. Removal of hepatic lipid may be impaired because of protein malnutrition, a relative carnitine deficiency, or oxidative damage to peroxisomes and other hepatic organelles. Hepatic lipidosis occurs in adult cats, and is manifest by signs of weight loss, depression, vomiting, and icterus. Diagnosis is achieved by evaluating laboratory and diagnostic imaging data, in conjunction with a liver biopsy. Aggressive tube feeding is the treatment of choice. With this treatment, survival rates are 60% to 80%.
