Soon, pet stores in San Francisco will only be allowed to sell rescue dogs and cats.
Now, according to an op-ed Tang and others wrote for the San Francisco Examiner, there are no known pet stores in the San Francisco area that sell dogs or cats.
But under the new rules, local pet stores are prohibited from selling non-rescue dogs and cats as well as puppies and kittens under the age of 8 weeks. The ordinance won't affect responsible breeders.
Officials hope this new legislation will help thousands of animals living in local shelters and act as a "deterrent" for local businesses. They hope it will prevent businesses from selling animals from "irresponsible mass-producing breeders that churn out puppies and kittens as if they were on an assembly line."
San Francisco will join several other cities that have implemented similar ordinances, including Los Angeles, San Diego, Chicago, Philadelphia, Boston and Austin.
According to data from the American Society for the Prevention of Cruelty to Animals, U.S. shelters take in around 7.6 million animals every year.
