非繁殖期的雌性蒙古沙鼠很容易吃掉所有可以接触到的幼崽。在繁殖中的雌性中，这种行为在分娩前几天停止。如果幼崽留在雌性身边，新生测试幼崽的同类相食行为会在产后 11 至 20 天之间卷土重来。然而，如果产仔在产后几小时内被清除，则 40% 的雌性会在产后 1-5 天吃食，72% 的雌性会在产后 6-10 天吃食。一窝幼崽的存在似乎抑制了幼崽的同类相食行为。用新生幼崽替换 6-10 天大的幼崽可以延长对幼崽同类相食的抑制时间。
Nonbreeding female Mongolian gerbils readily cannibalize all accessible pups. Among breeding females this behavior ceases a few days prior to parturition. If the litter remains with the female, cannibalism of newborn test pups returns between 11 and 20 days postpartum. If the litter is removed a few hours after parturition, however, 40% of the females will cannibalize on days 1-5, and 72% will cannibalize on days 6-10 postpartum. The presence of a litter appears to suppress pup cannibalism. The replacement of a litter 6-10 days old with newborn pups can prolong the suppression of pup cannibalism.
