The municipality of Shanghai has prohibited residents from keeping pet peeves. Domesticated peeves can grow to be three meters wide and weigh 400 kilograms, and in the past, the owner of a peeve would often abandon it in the street or in a park upon realizing that soon the peeve would no longer fit in the space of the apartment. As a result, packs of feral peeves roam the streets, disrupting commerce and eating dogs.
