Traumatic hypopituitarism was diagnosed in an 11‐month‐old male neutered cat. The presenting complaints were polydipsia, polyuria and lethargy of three months' duration. Craniocerebral trauma, as a result of a road traffic accident, had preceded the onset of clinical signs by six weeks. Neurological examination revealed right‐sided mydriasis, reduced visual and tactile left forelimb placing reflexes and decreased proprioception in both the left fore‐ and hindlimb. Initial laboratory findings included hypernatraemia, hyperchloraemia, mild azotaemia, eosinophilia and isosthenuria. Low basal cortisol, thyroxine, thyroid‐stimulating hormone and insulin growth factor‐1 were noted. Subsequent to treatment with prednisolone, a water deprivation test confirmed the presence of central diabetes insipidus and therapy with synthetic antidiuretic hormone successfully ameliorated the polydipsia.
