Which sign is most characteristic of feline hepatic encephalopathy?

Hepatic encephalopathy stems from the liver’s inability to detoxify gut-derived ammonia, allowing it to affect the brain. The hallmark of this condition is neurological dysfunction caused by ammonia accumulation, which disrupts brain neurotransmission and can lead to disorientation, incoordination (ataxia), and even seizures. In cats, these neuro signs are the most telling features because they reflect the direct impact of the toxin on the central nervous system. Other signs like vomiting, diarrhea, or general lethargy can occur with liver disease or systemic illness, but they are nonspecific and don’t point as clearly to hepatic encephalopathy. The presence of pronounced neurological abnormalities — especially disorientation, ataxia, or seizures linked to ammonia’s brain effects — best distinguishes hepatic encephalopathy from other conditions.
