JAAHA: A cautionary tale in feline hepatic lipidosis

Nutritional support is key to managing feline hepatic lipidosis (HL), but a new case study in the Journal of the American Animal Hospital Association (JAAHA) serves as a reminder that what we feed can be just as important as what we don’t we feed.

In this case, an 8-year-old spayed female domestic shorthair cat presented with a one-week history of anorexia and lethargy. Diagnostics—including liver cytology—confirmed hepatic lipidosis. With appropriate supportive care and nasoesophageal tube feeding, the cat initially improved. Liver values trended favorably, the cat’s appetite began to return, and her feeding tube was removed on day 17 of hospitalization.

However, the cat was still not eating enough. To supplement calories and protein, partial parenteral nutrition (PPN) was initiated using the only amino acid solution that the hospital had available. Within 24 hours, the cat developed acute neurological signs: vocalization, agitation, hypersalivation, tachypnea, seizures, and finally, progression to coma. Despite aggressive treatment for suspected hepatic encephalopathy (HE), the cat died two days later.

Further evaluation revealed hyperammonemia. While HE was initially suspected, several factors pointed toward a nutritional cause. Most notably, the administered amino acid solution lacked arginine—an essential amino acid in cats.
