Environmental enrichment is a necessary component of all research vivarium settings. However, appropriate enrichmentdecisions vary greatly depending on the species involved and the research use of the animals. The increasing use of ferrets inresearch settings-notably for modeling the pathogenicity and transmissibility of viral pathogens that require containmentin ABSL-2 to -4 environments-presents a particular challenge for veterinary and research staff to ensure that enrichmentneeds for these animals are met consistently. Here, we discuss the species-specific enrichment needs of ferrets, enrichmentconsiderations for ferrets housed in research settings, and the challenges and importance of providing appropriate enrichmentduring experimentation, including when ferrets are housed in high-containment facilities. This article is organizedto support the easy availability of information that will facilitate the design and implementation of optimal environmentalenrichment for ferrets used in diverse research efforts in vivarium settings.
