It’s a scientific fact that having a cat around can improve your health through lower blood pressure (often through a severed artery) and a greater sense of well-being (often by discovering your purpose in life is to open cans of cat food for a demanding boss).
However, there’s a reason why people admire cats so much and it’s because they exhibit traits that people admire and desire for themselves. After all, a cat is free and can go anywhere it wants while humans often feel locked into the regiment of a job that keeps their lives restricted and limited.
So the route to happiness is simple. Get a cat. If you can’t find happiness in your own life, you might as well devote your life to keeping a cat happy instead.
