The use of muroid rodents in the psychology laboratory

The rodent superfamily Muroidea represents a group of animals with much potential for comparative behavioral study as they are readily acquired, easy to maintain, and exist with sufficient ecological and behavioral diversity to enhance the likelihood of significant results. The superfamily includes Old World rodents, gerbils, hamsters, and a considerable variety of New World rats, mice, and voles which inhabit all 48 adjacent United States. Potential uses of muroid rodents, their taxonomy, and their husbandry are described with particular reference to the 28 species that have been maintained in the author’s laboratory. Although research on muroid behavior is just beginning, available data already support the proposed utility of these animals in behavioral research.
