Animals doing whatever they want because they can. I can not deny the fact that animals are very dear to us. The pleasure that these creatures give us has no reward, while their behavior is very natural.
In other words, pets manage to surprise us once in a while with their bizarre behavior. Sometimes you get the feeling that they own you and not the other way around. Cats top the list because their very indifferent nature makes them triumph in such events. While there are other animals such as dogs, squirrels and hawks showing their rebellious personality.
Actually I would say that because of their careless actions we love them as much as we do. They do whatever they want whenever they want without any care in the world.
