A 14-year-old MN DSH was presented due to the development of a voracious appetite and restlessness. The cat was previously diagnosed with hyperthyroidism and previous serum biochemical changes included hyolesterolemia and hyperlipasemia. CBCs and urinalyses were normal. On physical exam, the patient was tachycardic and a low grade heart murmur was auscultated, in addition to a mild increase in respiratory effort. Systemic blood pressure measurements were taken, but the results were inconsistent, ranging from 110-236 mm Hg. The fT4 result was elevated.

Systemic blood pressure measurements were taken, but the results were inconsistent, ranging from 110-236 mm Hg. The fT4 result was elevated. Medications for the treatment of hyperthyroidism and hypertension were initiated. The cat was re-presented for the development of vomiting for a 2 ВЅ day period. The owner described the cat as being hungry and wanting to eat, but being unable to keep anything down. The cat was bright, alert and responsive and had a normal temperature. No abnormalities were noted on abdominal palpation. Subcutaneous fluids, anti-emetics, and vitamins were administered and he was discharged the next day. The cat returned 2 months later; his owner had noticed that his appetite had been steadily declining over the last few weeks and had been losing weight. He had lost 1 lb 8 oz. since his previous visit. The patient was admitted to the hospital for blood work and supportive care. No abnormalities were noted on the blood chemistry and a low RBC count was present on the CBC. Abdominal radiographs showed thickened intestines which appeared to be bunched together without having any definitive edges.
