And I thought cats were basically good for nothing.
A cat with an uncanny ability to detect when nursing home patients are about to die has proven itself in around 50 cases by curling up with them in their final hours, according to a new book.
The cat, now five and generally unsociable, was adopted as a kitten at the Steere House Nursing and Rehabilitation Centre in Providence, Rhode Island, which specialises in caring for people with severe dementia.
Dr Dosa first publicised Oscar's gift in an article in the New England Journal of Medicine in 2007. Since then, the cat has gone on to double the number of imminent deaths it has sensed and convinced the geriatrician that it is no fluke.
The tortoiseshell and white cat spends its days pacing from room to room, rarely spending any time with patients except those with just hours to live.
If kept outside the room of a dying patient, Oscar will scratch on the door trying to get in.
When nurses once placed the cat on the bed of a patient they thought close to death, Oscar "charged out" and went to sit beside someone in another room. The cat's judgement was better than that of the nurses: the second patient died that evening, while the first lived for two more days.
Dr Dosa and other staff are so confident in Oscar's accuracy that they will alert family members when the cat jumps on to a bed and stretches out beside its occupant.
"It's not like he dawdles. He'll slip out for two minutes, grab some kibble and then he's back at the patient's side. It's like he's literally on a vigil," Dr Dosa wrote.
Dr Dosa noted that the nursing home keeps five other cats, but none of the others have ever displayed a similar ability.
I've been in this business long enough to tell you a few stories of my own. Like this...
