Cats Are Heroes!
Do you know what this black thing is? It is a plague rat! Well, this is just a toy, not a real live plague rat. And that is a good thing, because long ago, some rats carried bubonic plague. In the Middle Ages, millions of people lost their lives. How did people get the bubonic plague? From rodent fleas that jumped off the plague-infected rats! (Those are a different kind of fleas than the cat fleas that dogs or cats might have)
One of the reasons there were so many rats around is because, back then, cats were outlawed or even killed in medieval Europe because of superstitious beliefs about cats. With so few cats, the rat population exploded, making the plague even worse.
Eventually, people started to realize that the people who kept cats were less likely to get the disease. It was finally understood that rats were the real problem, and cats became the heroes of the story. Here is Harley, demonstrating what he would do if he ever saw a real plague rat.
Plague rattie, you are very bad! And fleas, too. I think this story proves that cats are to be treasured.
