I've been dying to get a cat but my apartment has a strict antifeline rule in my lease. Enter Sega Toys, who have created this lovely robotic cat, complete with touch sensors and real-kitty movements.
The kitty cat, whose name is "Yume-Neko Venus," which translates to "Dream Cat Venus", is kind of a dream. There's no litter to clean up, no hairballs, no stinky cat food, just a furry purring buddy.
True: There is also no heartbeat, but these guys probably have the same energy level as the real thing.
