I found her in the most odd fashion.
I first started looking about three hours ago. About 30 minutes into my search, my family's parrot started squawking even though my brother and I are the only ones home and no noise was going on in the room she was in. Confused, I went into her room and looked around, though I didn't find anything. My father called and asked me to change the parrot's food and water and cover her for the night, and when I was explaining little BPs escape, I walked into the parrot's room as I was mentioning the oddity of her sqwuaking, I turned my head and saw little BP curled up behind some stuff next to the other door.
I guess that's why she was so upset earlier -- she could see (clearly much better than I) little BP's movement. I can't believe the parrot led me to her like that. I would've never searched that room as thoroughly as I did my own.
