LOL Poor Liz! *hugs* I know exactly how you feel. I regularly spend hours and hours looking for one of my pet rats. Once I took even my bed apart to see if the rattie sat under it. When at 2:30 am I crawled out from under my book case, covered in dust and with a spider web floating from my ear, I found a rat sitting in my chair, watching me with great interest (and I daresay a considerable amount of amusement, too).
In such moments I wish I had goldfish instead of rats!
