SAN FRANCISCO — San Francisco's police crime lab, already plagued by a drug-skimming scandal, is quietly dealing with another pesky problem - cats.
A multiplying army of feral felines has moved into a lab hangar at the former Hunters Point Naval Shipyard where the Police Department stores evidence from old crimes. The cats have been sleeping, eating rodents and going to the bathroom around evidence items and police files, some of them boxed up, some out in the open.
