Championing native predators with science, sanity & heart since 1990 Predator Defense is a national advocacy organization working to protect America's vital native predators, including wolves, coyotes, cougars, bears, bobcats, and more. We educate, advocate and litigate to stop our government's brutal, unscientific and counter-productive war on wildlife. We also help those who have been injured or have lost pets to government traps and poisons. And we help people learn how to coexist with native predators.
