Whether you choose medical or surgical treatment of feline hyperaldosteronism often depends on the laterality of the disease
and whether metastasis has occurred. Cats with primary hyperaldosteronism caused by a nonmetastatic unilateral adrenal tumor
have a good prognosis with surgical excision. Medical management with potassium supplementation, antihypertensive agents,
and spironolactone therapy can be implemented for stabilization before surgery and in cases in which surgery is prohibitive.
The expected survival time for these cats ranges from months to years with a good to excellent quality of life. See Hyperaldosteronism case report: Reviving a senior cat's verve for an overview on how to handle this adrenocortical disorder in cats.
