Abstract

A 12-year-old cat, weighting 7.4 kg, suffering from fatigue, exercise intolerance, polyphagia, polyuria and polydipsia was presented. Obesity, a massive head, inferior prognathia and widened inter-dental spaces were noted on examination. Radiographic surveys showed organs enlargement. Labaratory results revealed hyperglycemia and glycosuria. Based on fasting hyperglycemia, concurrent hyperglycemia and glycosuria, diagnosis of diabetes mellitus was made. However, according to the poor diabetic regulation, clinical signs and the absence of other diseases, a tentative diagnosis of acromegaly was confirmed by increased plasma levels of growth hormone. Managing diabetes mellitus with increasing doses of insulin was the only possible therapeutic strategy.
