Depends on the state law. Iowa only requires that food and water be provided, and vet care when needed. I think there's a space requirement, meaning that x amount of space is required per animal, but it's minimal. I think for parakeets it is something like 9 in. per bird. I can't comment on other states, as I know only Iowa and federal law. Regulation of businesses, including pet stores, is mostly a function of the states.
