In 2007, Dr. David Dosa wrote an essay about Oscar for the New England Journal of Medicine. His story drew international attention. Oscar is a black and white tabby cat who lives at Steere House Nursing and Rehabilitation Center in Providence, Rhode Island. Since his arrival in 2005, Oscar has lived among the residents of Steere House's third floor dementia unit. Though outwardly he's "just a cat," Oscar has developed a unique ability to sense when patients on the third floor are about to die and he holds bedside vigils for patients during their last hours.
