A number of places, including New York City, have laws telling pet owners to clean up after their pets after the pet has pooped on a sidewalk or any public place, on a floor, wall, stairway or roof of any public or private premises used in common by the public, or on a fence, wall or stairway of a building abutting on a public. Authorized employees of New York City Departments of Health (including Animal Care & Control), of Sanitation, or of Parks and Recreation can issue tickets.
