Environmental enrichment and exercise housing protocols for mice

Here, we present a protocol that allows comparison of the effects of the standard home cage, environmentally enriched home cage with additional super-enrichment, and the exercise (running wheels only) home cage in laboratory mice. We first describe the steps to assemble these three types of cages, respectively. We then detail the assembly of super-enrichment arenas, which provide additional stimulation beyond that provided by home-cage enrichment. This protocol can help to improve reproducibility of results from studies involving environmental enrichment and exercise by offering consistent housing conditions between laboratories. For complete details on the use and execution of this protocol, please refer to Gubert et al. (2021).
