No Animals Were Harmed: The Controversial Line Between Entertainment and Abuse is a 2011 book by Peter Laufer. It is the third book in his untitled animal trilogy, following Forbidden Creatures in 2010 and The Dangerous World of Butterflies in 2009. The book explores what those who work with animals believe to be the line between using animals for entertainment purposes and abusing them. Meanwhile, the author recounts how his own opinions changed about that line when he talks to the different people about their beliefs. Source: Wikipedia (en)
