You Have A Visitor: Observations On Pet Visitation And Therapy is a photographic excursion of the use of animals in brining compassion, unconditional love, and emotional comfort to patients of medical facilities and residents of sheltered care environments. The chapters feature animal-assisted therapy (AAT) organizations across the country with articles and interviews describing their procedures and mission followed by photographs of volunteer teams that visit people who could use a little company. A resources section is provided which lists the featured organizations and also national organizations offering information and education on AAT programs and procedures. You Have A Visitor is a unique documentary and useful reference for anyone interested in helping others by volunteering with their family or personal pet. Highly recommended.
