Rats are on 3 different episodes, and are #9 on Cheats, #9 on Survivors, and #2 on Global Conquerors. They cheat us out of money, food, and even cheat death. Poison's have been becoming less effective, as rats are growing immune to them eating little tiny pieces at a time. They are also small enough to survive a 5 story drop. They can squeeze through any pipe, and chew through any pipe, including lead and concrete. They are extremely agile. They also reproduce extremely fast. The brown and black rat have conquered every country in the world.
