Rats are social animals and today group housing of rats is recommended in the Appendix A. If a dominance order is developed in a group subordinate animals might experience social stress. With more individuals to interact with in a cage, the overall activity in the cage will probably increase. Depending on which individual rats we randomly distribute into the cages, differences in group dynamics and social activity can occur. In two studies the social interactions of male Sprague Dawley rats in different group sizes and cage types were evaluated through direct observations. Comparisons were made between groups of two, four an eight rats in standard cages adjusted to the group sizes, as well as between pairs in standard cages and groups of eight kept in four connected cages of the Scantainer NOVO system (NOV) or in the Enriched Rat Cage system (ERC). The aims were to assess the effect of social interactions on the home cage activity, detect dominance orders in the different group sizes and to study effects of the cage types on social interactions. Rats in groups of four and eight had more social interactions, both neutral meetings and aggressive interactions, than rats kept in pairs (p
