Oscar

This is an older story (from nearly two years ago), but it's the first I had heard of the cat named Oscar.  He can be found at the third floor of Steere House in Providence, Rhode Island where dementia patients are cared for.  Oscar tends to sit with patients in their final hours of life.  This unusual "talent" has labeled him "an angel of death" to some but also a source of comfort and companionship.

Unsure this cat was real, Dr. David Dosa of Brown University studied Oscar.  He subsequently became a believer and wrote a book on his findings.  Reports on Oscar were also published in the New England Journal of Medicine.
