I so much want a Robot Cat. I live on the fifth floor, without a garden, and firmly believe that (real) cats should be free to go out and mingle with nature, hunt small defenseless animals etc. So a robot is perfect. Over the long-term, they’re probably cheaper than real cats… no food to buy, and no litter trays to clean. So I’m seriously thinking of placing an order when they’re made available outside Japan. When I was in Tokyo last year, I saw some metallic robot dogs in action, and they were incredible. There were four tables set up on the top floor of a department store, each containing dogs of various “ages” although they were all the same size. The mannerisms and body movement were just wonderful, just what you’d expect from, say, a six week old puppy or a fifteen year old hound, depending on which table was being looked at.
