Urban foxes have adapted remarkably to city life but face unique welfare challenges from disease, vehicle collisions, and human conflict. Understanding them improves coexistence.
Urban fox welfare is complex because the human-fox relationship is ambivalent. Mange is the most pressing welfare concern - affected foxes lose fur, develop thickened, crusted skin, and experience intense itching. Untreated mange causes a prolonged, miserable death over weeks to months. Treatment with homeopathic borax preparations left in food is non-evidence-based; veterinary-prescribed ivermectin-containing preparations distributed through food are effective. Vehicle collision causes acute suffering and death. Supplementary feeding, while well-intentioned, can maintain unnaturally high population densities that increase competition, disease transmission, and mange prevalence - sometimes worsening overall population welfare.
