Similarities between rabbits and rodents were once attributed to convergent evolution, but studies in molecular biology have found a common ancestor between lagomorphs and rodents and place them in the clade Glires. Rabbit physiology is suited to escaping predators and surviving in various habitats, living either alone or in groups in nests or ...
Rodents make up the largest order of mammals, with over 40% of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be kept short by gnawing.

The squirrels, rodents themselves, are eating California voles. California vole subspecies are listed as species of special concern and one is endangered.
A UC Davis study showed a nutty novel behavior in California squirrels: They're hunting like carnivores, taking down and then consuming other, smaller rodents.. As part of an ongoing 12-year study ...
New study suggest squirrels could be opportunistic omnivores. ... They found that more than 42 per cent of the interactions involved active hunting of the small rodents by ground squirrels.
Squirrels, being primarily herbivores, eat a wide variety of plants, as well as nuts, seeds, conifer cones, fruits, fungi, and green vegetation. Some squirrels, however, also consume meat, especially when faced with hunger. [21] [32] Squirrels have been known to eat small birds, young snakes, and smaller rodents, as well as bird eggs and insects.
Traditionally known for stuffing their cheeks with nuts, squirrels can be carnivorous — though recorded instances of the rodents hunting and killing other live vertebrates are rare, with few ...
