Abstract A 7‐year‐old female, spayed, domestic shorthair presented with a 24‐hour history of anorexia, lethargy and melaena. The cat was hospitalized and received treatment for hypovolemia, various electrolyte abnormalities and severe anaemia with a blood transfusion, intravenous fluids and medications. Abdominal ultrasound identified a pyloroduodenal nodule. Additional advanced diagnostics were not pur due to persistent intestinal haemorrhage and recurring critical status necessitating multiple blood transfusions. Surgical exploration identified a mass within the proximal duodenal lumen orad to the major duodenal papilla. The affected segment of duodenum and pylorus was resected, preserving the common bile duct, and a duodenogastric anastomosis was performed. Following surgery, the cat remained haemodynamically stable, and 5 days post‐operatively, all other clinical signs and electrolyte abnormalities resolved. Histopathological assessment of the mass was consistent with an intestinal adenoma. Six months post‐operatively, the cat was reported to have fully recovered without recurrence of clinical signs.
