Effects on Mice of Numbers of Animals per Cage: An 18-Month Study (Preliminary Results)
Mice were housed 1, 2, 4, or 8 per cage for 18 months. The more densely housed groups showed markedly reduced food consumption, slightly decreased mean body weights, and a smaller variance of body weights. Tumour incidence was not affected, but gastritis was more prevalent in the more densely housed groups.
