She wants me to rehome Baybi, but I'd obviously MUCH rather keep both.

No, the cage can't be moved to any other room, unfortunatley. There just isn't any space for it anywhere else.

There is definitely no possible way to shut Amber out from my room- this is where she has learned her litterpan is, her food and water, her bed, everything.. sometimes, during the day, if we even shut her out for ten minutes she starts yowling at the door.

We're just going to have to keep the spray bottle nearby if she jumps at the birdcage again..
