Why was Macho B euthanized? Why wasn’t he released to the wild to die naturally?
A. Macho B was euthanized after expert veterinarians at the Phoenix Zoo determined through blood tests and physical exam that the cat was in severe and unrecoverable kidney failure. Acting on the veterinarians’ recommendation, the U.S. Fish and Wildlife Service and the Arizona Game and Fish Department decided to euthanize him rather than rerelease him to the wild, where his debilitated condition would likely cause prolonged suffering before death.
