The predatory attack itself may differ between that of a carnivorous and omnivorous species, given the shift in lifestyles. I reviewed the information on 63 carnivorous rodent species. The approach here is to compare the predatory attack of carnivorous grasshopper mice ( and ) with that of the deer mouse () to identify specific differences. The predatory attack of a carnivorous rodent differs from that of the omnivorous rodent in its ability to overcome the flight initiation distance of potential prey, biting capabilities, use of its sensory modalities, seizure of prey, early and rapid development of a proficiency in its attack, vigor of its attack, and resistance to inhibition of the attack. The grasshopper mouse intimidates other rodents with which it competes for prey by a combination of its highly aggressive attack and advertisement of its presence. Focusing on the importance of overcoming the flight initiation distance of potential prey, the distinct and separate nature of the predatory attack, and behavior that reduces competition for prey can provide a framework for describing the evolution of a carnivorous lifestyle in other mammals.

由于生活方式的转变，肉食性和杂食性物种的掠夺性攻击本身可能存在差异。我查阅了 63 种肉食性啮齿动物的信息。这里的方法是将肉食性的草食性鼠（ 和 ）与鹿鼠（）的捕食攻击进行比较，以确定具体的差异。肉食性啮齿动物的捕食攻击与杂食性啮齿动物的捕食攻击不同，它能够克服潜在猎物的逃避起始距离、咬噬能力、利用其感觉方式、捕获猎物、在攻击中迅速掌握技能、攻击的活力以及对攻击抑制的抵抗力。草食性鼠通过其高度攻击性的攻击和存在的宣传来恐吓与其争夺猎物的其他啮齿动物。关注克服潜在猎物逃避起始距离的重要性、捕食攻击的明显而独立的性质以及减少对猎物竞争的行为，可以为描述其他哺乳动物中肉食性生活方式的进化提供一个框架。（PsycInfo 数据库记录（c）2021 APA，保留所有权利）。
