Found cat in Fishtown

This cat was crying on someone's stoop near Ramona Susan's and passersby told me it's been there for three days. Rang the bell and the residents said the cat isn't theirs but has been trying to get into their house all week. It's skin and bones and they said they've given it some food and water but can't take it in. I sat there and petted it for a long time while we discussed possible next steps and it's extremely friendly. Flopped down, made biscuits, didn't react to a dog walking by besides lifting head in curiosity. I don't live in Fishtown so couldn't take it with me, I did try picking it up (I know, I know, I'm an idiot, bear with me) and while it did not enjoy that experience, it didn't bite or scratch me - just made grumpy noises so I set it down. This cat is either someone's lost baby or about to be someone's new best friend. Anyone recognize?
