I have to wonder. Perhaps our human bias is what enables me to ask such a question. Perhaps even most mammals except maybe dolphins and chimps cannot think on such a level in order to create boredom. In this way, our intellect is both a blessing and a curse: It helps us do amazing things, but the need for mental stimulation at times can be annoying. But I have to wonder if I was correct in my assumption that most animals cannot experience boredom. How can one really know without being an animal mind reader? As a human, I have to wonder how they live such a life without a need for mental stimulation. Maybe they just simply "be." The concept of simply "being" however is hard for me to grasp.
All of this came from thinking about my cat.
