The dog that eats poop and poops food

Yes, so Rover likes to eat poop occasionally, but do we really need reminding of the fact? According to those wacky Japanese, we do, because the hottest new gadget for discerning dog owners is The Sum: a robotic composting can shaped like a dog [1].

Rover opens his mouth, and in goes up to 600g of poop per day. (That's a lot of turd.) The Sum breaks it down and, eventually, pushes out fragrant, healthy compost -- although where on the machine it exits from is probably best left to the imagination.

The Sum comes in four funky dog-shaped colours and costs a mere $900.
