Indeed, good luck with this, Halloween and trick or treaters adds extra disturbance to the mix. But I'm thinking, your Mama may not be truly feral but an abandoned house cat, which puts you miles ahead. It's very doubtful she will "attack you", she'll just be scared and defend herself, which is not the same thing at all. Actually I don't think even true ferals actually "attack" humans unless they are directly threatened, and even then it is in order to escape. If you can't catch her, what is the landlord going to do? Unlikely he will catch her either, maybe not even see her if she hides?
