It’s far fetched maybe but dogs can smell Parkinson’s and cancer before the person develops medically detectable symptoms. So maybe not so far fetched.
Doesn’t have to be a pet. Doesn’t detect when the person will DIE of cancer, yet it shows up later.
Birds have been shown to return to the same locations if they fit their needs. Perhaps it was indicating an illness.
Far fetched but absence of evidence is not evidence of absence.
Statistics are not science. Science requires real world evidence and other animals offer at least some evidence they can detect fatal illness in advance.
