Last night, while at the computer, she came out and jumped on the window sill. This am, she was sitting on the chair in the room. I was able to come in and let Binx out the back door.
She then went into her closet, sat in the litterbox, and HISSED at me. she hasn't hissed at me in at least 8 months??? I am so sad.

Phred, your suggestions are great. I do have a sort of latch to the door now, with scarves and a heavy weighted kettle on the floor. I had left the kettle away from the door Friday. I am concerned about doing anymore construction to her hidey hole. She 'used' to live in a box, then, she moved into the closet. I guess I will give it a few days, and see.....

While she is acting set back-ish in some ways, she is still sitting on the windwow sill, on the chair...but, she isn't sitting in the doorway to the closet like she used to...
