Which rodents are specialized predators rather than plant eaters?

While many rodents are herbivorous or opportunistic generalists that consume both vegetable and animal matter, some species have evolved to become specialized predators.1

The most notable example is the grasshopper mouse (genus Onychomys). These rodents are primarily insectivorous and carnivorous, feeding on insects such as grasshoppers, beetles, crickets, and scorpions. They are also known to stalk, kill, and consume other small vertebrates, including other rodents like kangaroo rats, white-footed mice, and voles. Because of their aggressive, territorial nature and predatory diet, they are often described as small analogues of larger mammalian carnivores.2
