In the early days of the American government, the Capitol building was infested with rats. To keep the rat infestation down, they brought in cats. Supposedly one cat has still remained in the basement of the Capitol, and is now known as the Demon Cat.
The Demon Cat appears as an ordinary black cat, but when spotted, it can swell up in size. Witnesses claim that they see the Demon Cat before traumatic events such as the assassination of John F. Kennedy and Abraham Lincoln, but others claim that most of the early Capitol building guards were drunk and could get the day off if they claimed to have seen the Demon Cat.
If there really is a Demon Cat, it probably can’t be worse than the demons currently running the government under the guise of politicians.
