ABSTRACT
Minmin, a 1-year-old male local cat weighing 4.3 kg has decreased appetite and an enlarged abdominal cavity. Based on physical examination, there was abdominal distension. Routine hematology and blood biochemical examinations were performed which showed chronic inflammation and abnormal liver and kidney function. Radiographic examination and abdominocentesis showed fluid accumulation in the abdominal cavity (ascites) with pale yellow fluid and thickened liquid consistency. The results of the rivalta test showed a positive accumulation of exudate which was characterized by a jellyfish-like formation. The cat was diagnosed with effusive feline infectious peritonitis. The therapies given are diuretic furosemide 5 mg/kg BW (twice a day) intravenously, antibiotic cefotaxime sodium 30 mg/kg BW (twice a day) intravenously, anti-inflammatory dexamethasone 0,5 mg/kg BW (twice a day) subcutaneously, hepato-protector betaine 2.5 mg/kg BW (every two days) subcutaneously, and keto acid 11 mg/kg BW orally (every two days). The results of treatment for one week only provide temporary results in reducing the degree of abdominal distension. The cat died in the sixth month after therapy.
