What to Expect at the Vet
When a cat stops eating for more than 24-48 hours, it can quickly develop hepatic lipidosis (fatty liver disease), a potentially fatal condition where the body mobilizes fat stores that overwhelm the liver. Inappetence in cats can be caused by dental disease, kidney failure, pancreatitis, GI obstruction, infections, or stress. Diagnostics to identify the underlying cause and supportive care including IV fluids, anti-nausea medication, appetite stimulants, and sometimes a feeding tube are standard treatment.
This is classified as a moderate emergency. Seek care today.
Note: Unlike dogs, cats cannot safely go without food for even a few days. Overweight cats are at especially high risk for hepatic lipidosis. If a feeding tube (esophagostomy tube) is required, it adds $500-$1,200 but can be managed at home. Mirtazapine and Entyce are commonly prescribed appetite stimulants for cats.
Your veterinarian will perform an initial examination ($50-$120) followed by diagnostic tests ($75-$600) to determine the appropriate treatment approach. Treatment costs ($50-$1,000) vary based on the specific intervention needed. Hospitalization and monitoring ($25-$780) may be required.
