Urban foxes are a natural part of city ecosystems in many countries, but face welfare threats from vehicles, snares, mange, and deliberate harm by residents who view them negatively.
Urban foxes occupy a contested welfare space — welcomed by many residents as wildlife to observe and enjoy, resented by others as pests. This division has welfare consequences: foxes in areas with hostile human attitudes face deliberate harm ranging from snaring to poisoning. Mange-affected urban foxes present a particular welfare challenge; left untreated, mange is a slow and extremely uncomfortable disease. Mange treatment programmes using homeopathic or conventional ivermectin baits have successfully treated individual foxes and reduced local prevalence. The welfare case for coexisting with urban foxes is supported by their role as pest controllers (eating rodents) and their general avoidance of conflict with humans when not deliberately fed or provoked.
