SAN FRANCISCO — San Francisco's animal control agency is proving that the print editions of newspapers remain just as vital in the digital age.

The agency relies on the papers to line cages and catch its puppy's poop. It is now turning to the city's public library to ensure a consistent newspaper supply.

The San Francisco Chronicle reports that the agency will pick up newspapers from the library about twice a month.

Agency supervisor Eric Zuercher says the arrangement has solved a big problem, noting puppies are poop machines.

The agency had previously relied on public contributions and donations from the Chronicle.
