The lawmakers in the city of San Francisco, after banning McDonald's Happy Meals, plastic bags, and the sale of bottled water, are now weighing a proposal to ban buying and selling of pets.

The main reason to propose the ban was to reduce the business for the puppy mills and other services that breed animals for sale, but too often mistreat them, care2 website reported.

The animal welfare advisory board proposed the ban, but the city's lawmakers and the Board of Supervisors, are yet to consider the ban.

The Humane Pet Acquisition Proposal was passed in June by the San Francisco Commission of Animal Control and Welfare to prevent the trade of any domestic living thing from Labrador to goldfish taking place within the city.

The city's pet stores owner told BBC that the ban would put them out of business.

The supporters in the city said that the ban is planned to stop the breeding of animals for profit. Supporters also said that the pets are kept in abusive, overcrowded conditions.

The ban would cover all pets: Kittens, snakes, hamsters and goldfish. It would also cover the sale of mice that are used as food for pet snakes; however, it would excuse sales of live fish, lobsters and poultry intended for human dinner plates.
