In 2017 California became the first state to ban the sale of puppies and kittens in pet stores except for possibly those animals from shelters and rescue facilities. This move was designed to encourage rescue and adoption. By then, some cities had already placed a ban on pet stores selling pets from breeding mills, and the momentum continues.
