Please tell me you had made the room it was in animal proof... Because if you hadnt you could be in trouble. If the room is animal proofed, then lift everyting off the floor, chances are it's in or under something.

I proofed my room after my snake got out a few times and found out it worked when a girl let a rat loose in my room, it was there for 2 weeks before I got sick of it and set a rat trap down.
