“Rats may not have the best reputation, but a new study suggests that they’re actually pretty good citizens. Researchers found that if a rat is in distress in water, another will save it, according to a post in Science Daily.”
Rats have always had an excellent reputation for intelligence. That’s why they are frequently used as lab animals. Humans dislike them since they steal food, sometimes bite people and spread disease (from a rat’s perspective, they are havesting food, driving off predators, and have no reason to worry about human’s public healthy and hygiene).
