This is an extraordinary little book, and Oscar is anything but ordinary. Dr. David Dosa writes about Oscar, a cat who lives in a nursing home for dementia patients, and his uncanny ability to know when the residents are close to death. Dosa provides a lot of valuable information about dementia and its effects - on patients AND their loved ones. He also interviews many family members, who tell of Oscar's effect on them and their parents. As an animal lover and someone whose own parent is in the early stages of dementia, I appreciated the educational aspects of this story, but also liked the respect Dosa has for the seemingly unexplainable.
