In the varied forms of veterinary medicine, Dr Susan Kelleher's practice may be one of the more unusual. Known as Dr K, she runs South Florida's Broward Avian and Exotics Animal Hospital, and this series follows the staff as it cares for rabbits, ferrets, foxes, fish, birds, reptiles, marsupials and primates. As do some other vets, Kelleher thinks domesticating wild animals like monkeys is a bad idea, but that feeling doesn't interfere with her taking care of them: `If it will fit through the door, I'll treat it', she says.
