Harley Rose Gifford and Britney Singleton, both 19, have been stealing iPods, jewelry and money since July.
Detectives have dubbed the lovers ‘the Thelma and Louise bandits’ after the 1991 crime film starring Susan Sarandon and Geena Davis.
Upper Darby Police Superintendent Michael Chitwood told the Philadelphia Enquirer they looted the homes, left them ransacked and either walked or took public transport home.
He said: "They just enjoyed stealing. They used people's homes as their own private shopping centre. They took whatever they could get their hands on."
Detectives had originally thought they were stealing to support a drug habit but eventually concluded they were "just thieves, pure and simple."
Astonishingly the pair claimed to have encountered a lion on one of their robberies in Cardington, PA - something which cops have yet to verify.
Superindent Chitwood added: "If we find a lion it will be a bigger story than this."
