Today we will be talking about a hated but misunderstood animal. The rat. The sight of a rat might frighten you. Or it might make you sick to your stomach. Well, perhaps not everyone. In some countries, dishes made with rat meat can be rare and sometimes pricey -- what we call a delicacy. Plus, rats are useful. With their extreme sense of smell, people can train giant rats to find land mines and even tuberculosis. But do these things make people love rats? No. For the most part, rats are not beloved animals.
