Sucess! I took one final looks, with no hope left in me. I was sitting in my torn apart room with Monty when I noticed something. Where the carpet meets the heater it has a lip that curved up, and under it is hollow. This is on the basement floor, so it is not held down, so I knew she could have gotten in via the gap in the corner. So I felt around, pushing down on the lip and kept feeling it was hollow. I hit a hard spot, but since there was no movement I figured it was not her. I lifted it up and there she was! She was feezing cold, had a white power on her(?), and she was being so cute. I think I know how she got out too, but I'll be keeping an extremely close eye on her. I made an image to better descibe where she was for you guys.
