According to the new 8th edition of the "Guide for the Care and Use of Laboratory Animals." Based on Table 3.2 on page 57 of the new "Guide", adult mice (>25 grams body weight) have a recommended minimum 15 square inches of space per animal. The average adult mouse will weigh approximately 30 grams. Using this minimum, cages currently in use will only allow 5 adult mice per cage.

Emory University’s PHS Assurance states that we will adhere to the "Guide" and PHS Policy. The IACUC must conduct at least one of its semiannual inspections incorporating the new "Guide" before December 31, 2012. The IACUC has already conducted one site inspection of all facilities and did not cite any cages with more than 5 adult mice/cage. With this implementation timeframe in mind, any mouse cages containing more than 5 adult mice found after May 1st will be reported to the IACUC.

Any cages found with more than 5 adult mice found on the next semiannual site inspection will be documented as a deficiency and reported to our Institutional Official in the semiannual report as required by the Animal Welfare Act.

Following the new revised "Guide" is federally mandated by our regulatory bodies and expected by our accreditation agency. Please note that the IACUC has revised its policy to comply with the new "Guide". Please see Mouse Overcrowded Cage Policy (PDF).
