Do Rats Kill Each Other?

The question “Do rats kill each other?” has been a persistent topic in rat science. The answer to this question is not as simple as it might seem. Rats are a highly social species and, therefore, their actions may be influenced by their social group and by the type of environment they live in. Female mice, for example, may condition males to avoid their newborn pups. Interestingly, seven out of eight male rats that lived with a lactating female developed wounds on their front paws and tails. This may explain the fact that male rats only attack their offspring after about nine days of age.

Rats who are engaged in a fight often fight with their sharpest claws and teeth. It is not unusual for them to attack a person when a fight is in progress, but it is best to avoid getting involved if possible. The best way to intervene is to use an inanimate object or thick gloves to separate the rats. Alternatively, you can try to distract the rats with water.

Rats usually kill each other over territory or food. Rats may also kill one another when they are threatened, but this is rare and typically occurs only when the population of rats becomes too large. Most rats do not attack each other unless they feel threatened, but if they do, they will avoid each other and not bother them. In addition to territorial disputes, rats will also often eat their dead cage mates as it is a natural instinct that helps them avoid the spread of disease and reduces their chances of becoming a target for predators. Some rats may also get aggressive when they are going through their teenage phase, and this is linked to their hormonal levels.
