The mystery has been solved.

Last night around 1 a.m. I got up and checked on my little family. Sure enough, they were ALL on the carpeted floor outside the new box I brought home.

It seems little Miss Mattie Grace was trying to make ME think I was crazy!!! SHE moved them all out onto the floor! I just shook my head and went back to bed. This morning, while she ate, I took a bunch of towels and placed them on the floor for her as a makeshift bed. She's happy as a clam now! And now I can get some sleep!!
