Feeding urban wildlife is widespread but can cause welfare harm through dependency, disease transmission, habitat congregation, and nutritional problems.
Urban wildlife feeding welfare has context-dependent outcomes: supplementary food during harsh winters with low natural food availability can prevent starvation; year-round feeding of abundant food creates dependency, nutritional problems, and disease risk. The welfare calculus depends on species, season, and feeding practice. The general principle — provide appropriate food in limited quantities during periods of need, rather than creating permanent dependency — protects welfare without eliminating beneficial supplementation.
