I'd feed her, because she will get hungry. I couldn't call the ASPCA, because if nobody claims her she's a goner. I might tell them I found her and am caring for her until someone claims her. I'd put up flyers, and call no kill shelters to report that you have her. Thanks for taking her home, and not leaving her roaming the streets.
