Which document provides guidance on minimum cage height for laboratory mice?

• A. The Guide for the Care and Use of Laboratory Animals
• B. The Animal Welfare Act
• C. NIH Guidelines for Research Involving Animals
• D. Institutional Animal Care Policy

Answer: (A)

The guidance on minimum cage height for laboratory mice comes from the Guide for the Care and Use of Laboratory Animals. This document is the primary reference for housing standards, covering cage dimensions, space, enrichment, and other husbandry details to help mice move, stand, and behave normally.

The Animal Welfare Act sets the legal framework for humane care and requires institutions to have oversight, but it does not specify exact cage measurements. The NIH Guidelines for Research Involving Animals describe broader care and use requirements for NIH-funded work and often point to the Guide for specifics, but they don’t provide the numeric housing dimensions themselves. An Institutional Animal Care Policy is an internal policy that may align with the Guide but isn’t the universal standard for cage dimensions.

So, for exact minimum cage height and other housing details, refer to the Guide for the Care and Use of Laboratory Animals.
