How does the Guide for the Care and Use of Laboratory Animals influence mouse care?

• A. It prescribes exact daily routines for each facility.
• B. It is optional guidance with no regulatory impact.
• C. It provides the framework for housing, husbandry, procedures, and welfare standards used by institutions.
• D. It only covers dietary requirements.

Answer: (C)

The Guide for the Care and Use of Laboratory Animals functions as a framework that institutions use to shape all aspects of mouse care, from housing and husbandry to procedures and welfare standards. It lays out the general criteria and best practices that ensure humane treatment, while leaving room for adaptation to different species, facilities, and research needs. Because these standards are widely adopted and referenced by oversight bodies, compliance with the Guide is integrated into institutional policies and protocol reviews, making it a central driver of how mouse care is actually implemented. This isn’t a rigid, one-size-fits-all schedule, and it isn’t limited to diet; it covers housing conditions, enrichment, handling, procedures, analgesia, euthanasia, and overall welfare. It also isn’t optional guidance—many funders and regulatory programs expect institutions to align with its principles.

So the correct idea is that the Guide provides the framework for housing, husbandry, procedures, and welfare standards used by institutions.
