Abstract
An initial experiment assessed mouse killing in the rat following different periods of recovery from a food deprivation schedule. Testing which immediately followed food deprivation resulted in a high mouse killing rate relative to rates observed after a 2-week recovery period and control conditions. A second experiment investigated the effects of intraspecies competition, independent of food deprivation, on mouse-killing behavior in the rat. In contrast to previous reports, no significant competition effects on interspecies aggression were found.
