Tendency to exhibit muricide was examined in 481 adult rats of 15 inbred strains. Marked strain differences were observed; frequency of mouse killing ranged from 0 to 91% among the males and from 0 to 68% among the females. Whether males and females differed in their propensity to kill mice also appeared to be strain-dependent. Overall, there was a significant correlation between the frequency of mouse killing by males of each strain and that of females.
