Cannibalism in rodents is not uncommon. Since rats are scavengers, they will consume corpses of deceased rats so the smell doesn’t attract predators to their nest or colony, as well as to ration nutrients when food is difficult to find.
Wild rats are typically scavengers but are also predators (especially of insects, smaller mammals, and birds). Scavengers generally own adaptations and instincts to help them both be good hunters and escape or defend against predators. A rat’s predatory instinct is not really evident.
When in groups, rats can stand on hind legs to assert dominance. Pregnant rats have been known to sometimes become aggressive to other male and female rats.
