Abstract Mice were observed for a period of 37 weeks by a continuous monitoring procedure. The data are presented in weekly blocks and differences across time are noted. A definite increase in fighting was observed beginning at approximately 5 weeks and increasing to a peak at the 7th week, then declining to a low at 12 weeks. A later peak occurred around the 19th week. In overall amounts of aggression the females were low, male littermates (MLM) intermediate, and male nonlittermates (MNLM) were highest.
