Thanks all! I've only had the bare minimum time for one-on-ones with her for a few days now due to an ongoing family emergency, so today was my first day to get her used to it.
Unfortunately, I forgetfully left a balloon in the room and once she noticed it about an hour into being out (I lightly brushed against it, so it moved), she freaked and crashed into the wall. She's fine, and the terror was removed, but after she got her cuddles she went to the cage and refused to come back out, so I guess I'll start tomorrow. This may set us back a bit, but with time. Poor angel.
I'll update when I have some cute pictures of her actually with it, lol.
