Plain-English summary
A 1-year-old neutered male domestic shorthair cat was brought in for excessive thirst (polydipsia) that started after he fell from a height of 8 meters about four weeks earlier. The vet suspected a condition called central diabetes insipidus, which was confirmed through tests showing his urine was too dilute. Initially, a treatment applied to his eye didn't help, but switching to a subcutaneous (under the skin) form of the medication DDAVP successfully controlled his thirst. Now, 17 months later, the cat is doing well with this treatment and no longer shows signs of excessive thirst.

Abstract
A 1-year-old neutered male domestic shorthair cat presented with a 4-week history of polydipsia that began immediately after an 8 m fall. Trauma-induced central diabetes insipidus was suspected on the basis of the identification of hyposthenuria, normal haematology and serum biochemistry profile and unremarkable abdominal ultrasound examination. Failure to concentrate urine with water deprivation followed by production of hypersthenuric urine with administration of the synthetic antidiuretic hormone, Damino-8-D-arginine vasopressin (DDAVP), confirmed the diagnosis of central diabetes insipidus. Treatment via conjunctival administration of DDAVP failed to attenuate the polydipsia, however, resolution of polydipsia was achieved with subcutaneous administration of DDAVP and the cat remains eudipsic with twice daily subcutaneous DDAVP administration 17 months after diagnosis.
