The ARC recently revised the Policy, Environmental Enrichment, primarily to clarify and update enrichment practices in use for mice and rats. You will recall that the ARC announced a 30-day comment period to invite feedback on the proposed changes; as no comments were received from the research community, the proposed Policy changes were implemented as previously described. The revised Policy is available at the Environmental Enrichment web page.
We encourage you to review the revised Policy with your research team. If you require an exemption to the Policy, this must be justified and documented in your approved ARC protocol.
Please do not hesitate to contact us at 310-206-6308 or firstname.lastname@example.org if you have any questions.
