    TLDR The cat had a pituitary tumor causing hormone imbalance and related health issues.
    A 9-year-old male castrated cat was diagnosed with pituitary-dependent hyperadrenocorticism, presenting symptoms such as polyuria, polyphagia, pendulous abdomen, truncal hair loss, congestive heart failure, and insulin-resistant diabetes mellitus. Diagnostic tests showed inadequate serum cortisol suppression after dexamethasone, exaggerated cortisol responses to ACTH stimulation, and high plasma ACTH levels. Pathological examination revealed bilateral adrenocortical hyperplasia and a pituitary adenoma, confirming the diagnosis.
