TLDR  Trilostane helped a cat with a hormone issue but the cat later died from a kidney infection.   
  This report documented the use of trilostane, a steroid synthesis inhibitor, to treat a domestic shorthaired cat with pituitary-dependent hyperadrenocorticism. Trilostane alleviated the severity of clinical signs and was well tolerated. However, the cat later died of renal failure due to a secondary fungal infection of the urinary tract.
