Choosing effective animal welfare organizations to support requires understanding their methods, evidence base, scale of impact, and cost-effectiveness. Evidence-based giving multiplies welfare impact significantly.
Evidence-based giving to animal welfare organizations maximizes the welfare benefit of charitable dollars. Not all animal welfare organizations achieve equal impact — some focus on companion animal welfare where donors' natural sympathy lies but where scale of impact is limited; others target factory farming or wild animal welfare where scale of impact is vastly larger. Impact assessment considers what the organization would achieve with additional funding beyond existing revenue, not just total activities. Supporting organizations that can credibly scale their impact with additional resources produces better welfare outcomes than supporting large organizations with saturated funding needs.
