This has to be the funniest cat video on the web right now, and I got to wondering whether cats understand each other. I seriously think they do because before two cats fight they make this strange long noise to each other before they attack. They seem to speak the same language. So as a test I recorded a cat’s meow on a tape recorder and hid it under the pillow. I set it on repeat and my cat went right to the pillow and laid on top of it. She started to meow as well. This is the main difference between Dogs and Cats. Watch the video carefully and you will see that the cats wait for the other to finish. They try not to purr over each other. On the other hand, dogs dark over each other but that seems to be just that….barking. Sometimes dogs just keep barking by themselves for no reason for hours. It is like talking to a person and five minutes into the conversation you realize that the person is actually talking to himself….
