Plain-English summary
A 13-month-old female domestic shorthair cat had been drinking and urinating a lot for 10 months after being hit by a car. When the vet examined her, they noticed she had trouble seeing and didn't respond normally to visual cues. Blood tests were normal, but her urine was very dilute, which indicated a problem. A special test showed that her body wasn't concentrating urine properly, but when given a synthetic version of a hormone that helps with this, her urine concentration improved. Treatment with this hormone worked well for her over the next 19 months.
Abstract
A 13-month-old female domestic shorthair cat presented with a 10-month history of polyuria and polydipsia that began after having been hit by a car. Neurological examination revealed visual deficits and an absent bilateral menace response. Hematological and serum biochemical analyses were within reference values, but hyposthenuria was identified. Failure to concentrate urine during the water deprivation test followed by an increase in urine specific gravity after administration of synthetic antidiuretic hormone (ADH) suggested a diagnosis of central diabetes insipidus. Subcutaneous or oral administration of synthetic ADH was effective in central diabetes insipidus treatment during the 19-month follow-up.
