Oscar (therapy Cat) - Possible Explanations

Possible Explanations

It is not certain if Oscar's behavior is scientifically significant. Nor is there certainty whether his behavior results from inborn abilities or is the result of learned behavior from him living nearly his entire life in an end-stage medical facility where death is quite common and expected.

Dr. Joan Teno, a professor of community health at Warren Alpert Medical School of Brown University in Providence who cares for Steere House residents and sees Oscar on a regular basis, said: "It's not that the cat is consistently there first. But the cat always does manage to make an appearance, and it always seems to be in the last two hours."

Dr. Dosa (also affiliated with Alpert Medical School), who describes the phenomenon in an essay in the July 26 issue of the NEJM, says that "(Oscar) doesn't make too many mistakes. He seems to understand when patients are about to die," speculating that "the cat might be picking up on specific odors surrounding death." Dr. Teno supports this view: "I think there are certain chemicals released when someone is dying, and he is smelling and sensing those."

Some animal behavior experts say the explanation about Oscar sensing a smell associated with dying is a plausible one. "I suspect he is smelling some chemical released just before dying," says Margie Scherk, a veterinarian in Vancouver, British Columbia and president of the American Association of Feline Practitioners. "Cats can smell a lot of things we can't," she says. "And cats can certainly detect illness." Dr. Jill Goldman, a certified applied animal behaviorist in Laguna Beach, California says that "Cats have a superb sense of smell," adding that keeping a dying patient company may also be learned behavior. "There has been ample opportunity for him to make an association between 'that' smell ".

The sense of smell may, however, be just one explanation. Dr. Daniel Estep, a certified applied animal behaviorist in Littleton, Colorado suggests that "One of the things that happens with people who are dying is that they are not moving around much. Maybe the cat is picking up on the fact that the person on the bed is very quiet. It may not be smell or sounds, but just the lack of movement."

Dr. Thomas Graves, a feline expert from the University of Illinois, told the BBC: "Cats often can sense when their owners are sick or when another animal is sick. They can sense when the weather will change, they're famous for being sensitive to premonitions of earthquakes."

Pitlik (2009) used Oscar as a metaphor for the infection by carbapenem-resistant Klebsiella pneumoniae. There is no definite evidence of the virulence of KPC, and this bacterial infection is not the cause for the patient's death, but an indication of the poor prognosis.
