I know I'm bumping but good news: I found Tzar (the cat) a home. A friend of mine met him and fell in love with him. She was planning on moving to a new place anyways, so she is now in the process of moving in to an apartment where cats are allowed.
I'm quite happy with the outcome; Tzar will get a good home, and I don't have to run the Craigslist gauntlet.
