Anyone with a computer and a cat knows what happens next. Any time you need to use your computer, your cat inevitably walks across the keyboard and often lays across it or just stomps around, screwing up whatever you’re trying to do on the computer.
In case you’re wondering why your cat would do that, it’s basically because your cat wants your attention. By interfering with your actions, the cat guarantees you’ll pay attention to it. By rewarding the cat by petting it or giving it food, you reinforce the cat’s desire to walk across or lay down on your keyboard in the future.
Now you have to wonder who’s training who?
