I went away for a few days and came home to find both of my female cresties out of the cage. The first one was easy to find, she was hanging on the curtain. The second I literally tore the room apart to find her. I finally found her in the laundry basket. She had buried herself in the clothes. When I stoped to think about it, where I found them made sense. The female I found on the curtain, is the one that is always stuck somewhere high in the cage. The one in the laundry, has always buried herself.
