This journal publishes reports and articles on methods of experimentation, husbandry, and care that demonstrably enhance the welfare of non-human animals on farms, in laboratories, in wildlife/zoo settings, and as companions. JAAWS is a conjoint project of The American Society for the Prevention of Cruelty to Animals (ASPCA) and Psychologists for the Ethical Treatment of Animals (PSYETA). Each issue includes several reports covering scientific experiments or demonstrations that present evidence relating to prime issues of applied animal welfare science. All submitted manuscripts are peer-reviewed by a panel of section editors who oversee an even more complete review by a distinguished board of editors. JAAWS also publishes feature articles that present particularly significant or provocative contributions to our understanding of animal welfare new empirical data or reevaluations of available data, or conceptual or theoretical analysis. These feature articles are accompanied by several invited commentaries that critically discuss the contribution--particularly in regard to its implications for animal welfare.
