"The Tempe City Council will vote to change what types of pets can be sold at city pet stores Thursday. The change is a direct response to state law enacted earlier this month.   Tempe and Phoenix had previously banned the sale of commercially bred cats and dogs and required pets to come from shelters.  A law signed by Gov. Doug Ducey prevents Arizona cities from regulating animal sales, pre-empting the city laws."
