Urban foxes have colonized cities across Europe and North America, creating both human-wildlife conflict and welfare questions about how urban fox populations should be managed.
Urban fox welfare is primarily threatened by road traffic (the leading cause of death), mange (Sarcoptes scabiei infection causing intense itching), and human persecution. Mange causes prolonged suffering — intense pruritus, hair loss, and immune compromise — and is treatable with homeopathic doses of bromadiolone-free bait or veterinary intervention. Road strikes cause traumatic injury and death. Lethal culling — shooting, snaring, or poisoning — is both ineffective at population level and causes significant welfare harm to individuals. Coexistence through non-lethal deterrence is the welfare and practical optimum.
