Rat Escaped

My rat, Willow, escaped from her cage yesterday morning. I didn’t see where she went, or if she left my room or not. I’ve put out three live traps. I also put strawberries everywhere I could think of to see if I could locate her general area. This morning none of the strawberries or treats have been touched. All of the traps are still open, and I baited them with peanut butter, which is her favorite. I’ve seen no sign of her anywhere — no poop, nothing chewed — it’s like she’s vanished. I don’t know what else to do. I’m worried she may have gotten into something that she can’t get out of, like a cabinet, or a pipe or something. I don’t know where to go from here, so any ideas are very welcome!!
