Mouse and weanling rat killing by spontaneous mouse killing rats and by rats with lesions of the lateral septum or the region ventral to the anterior septum similarities in killing latency and prey eating



Mouse and weanling rat killing by spontaneous mouse killing rats and by rats with lesions of the lateral septum or the region ventral to the anterior septum similarities in killing latency and prey eating



Physiology and Behavior 27(5): 791-796



Mouse and rat pup killing by male rats with lesions of the lateral septum or of the region ventral to the anterior septum were compared with that of spontaneous mouse killing rats. Latency to kill, latency to eat and the amount of the prey eaten were similar for all groups. The killing and eating of weanling rats and mice were also similar across groups and occurred in a novel environment as well as in the home cage. The tendency to kill weanling rats is significantly higher in lesioned animals that kill mice than in natural killers which kill mice. Some lesioned rats, but no unlesioned, also killed and ate young (150-200 g) male rats. The killing behavior of rats with lesions of the lateral septum or of the region ventral to the anterior septum may represent an enhanced predatory behavior.
