Here's how much it could cost to host pandas at San Francisco Zoo, report says

SAN FRANCISCO (KGO) -- New details about the push to bring Giant Pandas to the San Francisco Zoo.

The big challenge will be paying for them, and we're getting a better idea of how much it'll cost.

The San Francisco Chronicle reports the zoo's financial director put the cost at as much as $70 million for a decade.

That includes the panda enclosure, thousands of pounds of bamboo per month and the cost to rent the pandas from China.

Animal rights groups claim $70 million is a low estimate.

Mayor London Breed's fundraising plan is focused on raising $25 million.

The zoo's deputy director says it's premature to put a price tag on what pandas would cost.
