This video shows Peter Cohen's house, transformed into a "Cat world". Cohen, a resident of California, spent $70,000 to create an entertainment playground for rescue cats. "This is their (cats') house and we're living with them". "We can't solve the world's problems, but I can solve this tiny problem for these cats". It makes me feel better, because I know there are still people out there who care, there will always be people who care... People can be the worst but as we can see from this video, they can also be the best. If everyone could try to do one little thing to ameliorate something they love or care about, the world would probably become much better. Because progress is a step-by-step process, and everything is hidden in detail.
