It may not beat the Elmo TMX when it comes to over-the-top robotic functions, but the Robo Cat aka Yume-Neko Smile (Dream Cat Smile to you) is hoping to replace your current feline friend. The dream cat, who looks more like a stuffed cat, has five sensors throughout his body that react to your touch. Pet his head and the kitty will start purring or stroke his back to put him to sleep. Just imagine, a cat you don't have to feed, bathe, or care for all the time. Watch the video to see how it works.
