We love our pets. Dogs, cats, birds, reptiles, and other species have become an essential part of more families than ever before-in North America today, pets outnumber people. Pet owners are drawn to their animal companions through an innate desire to connect with other species. But there is a dark side to our domestic connection with animal life: the pet industry is contributing to a global conservation crisis for wildlife-often without the knowledge of pet owners. In Unnatural Companions, journalist Peter Christie issues a call to action for pet owners. If we hope to reverse the alarming trend of wildlife decline, pet owners must acknowledge the pets-versus-conservation dilemma and concede that our well-fed and sheltered cats too often prey on small backyard wildlife and seemingly harmless reptiles released into the wild might be the next destructive invasive species. We want our pets to eat nutritionally healthy food, but how does the designer food we feed them impact the environment? Christie's book is a cautionary tale to responsible pet owners about why we must change the ways we love and care for our pets. It concludes with the positive message that the small changes we make at home can foster better practices within the pet industry that will ultimately benefit our pets' wild brethren.
