A city in Taiwan is trying to keep the streets clean by offering cash for collected dog poo.

City officials in Taichung, which has a population of one million, said on Wednesday the environmental protection bureau would give vouchers worth 100 Taiwan dollars ($3) for every kilo of dog poo collected. In areas of the city especially affected, the reward will be for every half-kilo.

In related news, Taichung is witnessing a sudden surge in demand for high-fiber dog food which is now being sold in convenient single-serving sizes priced at 99 Taiwan dollars.
