(a) This 5-year-old male neutered Devon Rex cat was presented with a history of lethargy, mental dullness and inappetence. The cat also had diabetes mellitus. This patient had a very low circulating total thyroxine concentration, as well as an increased canine TSH concentration, confirming primary hypothyroidism.There was a seborrhoeic hair coat that was easily epilated;note the bilateral ceruminous otitis.
