i wouldn't just leave her out and about. i'd keep her in a carrier and let her out of it a couple of hours a day at first so tuffy can sniff her and get used to there being another cat.
i didn't read your first post so i don't know how long you've had her but a week to 10 days is the usually "introduction" time. i would not leave her out alone with him for at least another month.
