It seems to me that there's something gross about making a dog poop composter shaped like a dog, a design that makes you put dog poop into a dog's mouth.

Only Japan would come up with the Sum, a robotic trash can designed by Tohoku Kankyo. Simply open the poor dog's mouth, put in pet poop and old food, and using some "fancy bio substance" it'll break it down and make it not stinky. It can handle about 600 grams of poop or food per day, which is more poop than I'd want put in my mouth per day, but I'm no robotic trash can.

The Sum can be yours for the perfectly reasonable price of $900. [Sum via Japan Probe]
