Some asshole moved out of my complex and left their cat to die. Help. (Lefferts Gardens)

From Craigslist (see link to contact) So, I live right off of the Winthrop Street subway stop. Someone in my community moved out right before the blizzard and just left their cat in the lobby. Predictably, management evicted the cat and she's just been sitting out in the patio area, freezing, and waiting for her owners to come home. She is the sweetest cat in the world. I have seriously never encountered such an affectionate animal. Unfortunately, however, I am not allowed to have a pet by conditions of my lease. I called animal control and they said they'd euthanize her within 72 hours if she isn't adopted, so I'm trying to find a better option than that. The only no kill shelters in this borough are full-up. If anyone at all is interested in helping out or has ideas, please get in contact with me, either via email or via phone. I really want to save her.
