Red foxes have adapted remarkably well to urban environments across the world, yet individual foxes face significant welfare threats from mange, vehicle strikes, and human-wildlife conflict that leads to lethal control.
Urban foxes face welfare threats that are almost entirely anthropogenic. Mange - spreading rapidly through urban fox populations due to den sharing and high population density - causes weeks of intense itching, hair loss, and emaciation before death. The itching is relentless and sleep-disrupting; affected foxes scratch continuously. Vehicle strikes cause sudden violent death or traumatic injury that may be non-immediately-fatal, leaving animals to suffer from internal hemorrhage or orthopedic injuries. Mange treatment programs, where volunteers provide medicated bait, have demonstrated successful population-level mange control - showing that the welfare of urban wildlife populations can be actively improved through community action.
