Animal welfare donations vary enormously in impact per dollar. Understanding how to evaluate and choose high-impact giving opportunities helps advocates maximise the welfare benefit of their charitable contributions.
Effective giving for animal welfare applies the same logic as effective altruism more broadly: the question is not just whether an intervention helps animals, but how many animals it helps and at what cost per animal helped. Rescue and rehabilitation organisations provide direct care but typically at high cost per animal. Policy and corporate advocacy, despite being less emotionally compelling, often delivers welfare improvements at far lower cost per animal affected. Advocates who approach their giving with rigorous attention to evidence and scale can multiply the welfare impact of every dollar donated.
