This book is an inspiration to anyone who wants to make a difference and save the lives of animals. It takes a good look at the big-picture of the major debates about how humans treat animals and how to effectively protect them in today's society.
The Humane Society of the United States offers numerous publications to help you improve your work for animals and to help you educate your community.
The Michigan Pet Fund Alliance is an excellent resource for citizens interested in improving their local shelters - with the goal to achieve No Kill through training, technical assistance, education and advocacy - to end the killing of healthy and treatable homeless cats and dogs in Michigan.
