A 17-year-old, castrated male domestic shorthair cat presented with nonspecific clinical findings of three days' duration. Complete blood counts and serum biochemistry profiles revealed evidence of hepatic dysfunction. Ultrasonographic evaluation revealed abnormalities consistent with pancreatitis, with suspected pancreatic duct dilatation in the left limb of the pancreas. Surgery and eventual necropsy confirmed a diagnosis of pancreatitis, along with pancreatic duct dilatation. Dilatation of the pancreatic duct may be another ultrasonographic change to look for when suspecting feline pancreatitis.
