Porcupines in North American and African urban fringe areas create conflicts with domestic animals and gardeners, but are often the victims of cruel control methods despite being non-aggressive animals.
Porcupines are non-aggressive animals that cause conflict primarily by existing near humans. Their defense is entirely passive — quills cannot be thrown and are only deployed when the animal is cornered. Dogs are injured by their own investigative behavior, not porcupine aggression. Lethal control of animals that cause conflict only through their presence, in the absence of non-lethal alternatives, is difficult to justify ethically. Prevention through responsible dog supervision and simple garden deterrents eliminates the vast majority of porcupine conflict without any animal harm.
