There is so much to think about in this book, from human/animal interaction, family relationships and scientific testing. I read this book years ago, several years after seeing an art installation at the DeCordova Museum. The museum had lifesize 3d fabric monkeys hanging on vines. The exhibition was about animal testing and included a photographs of the monkeys. Their faces looked so human like and expressive. From this room, you entered another room, where there were photographs of the ravaged faces and bodies of AIDS vicitms. it left me wondering about the costs and benefits of animal testing. I still don't know the answer.
