Stupid rat

I wanted to strangle Ceit last night. She was banging on anything she could bang on- her hanging coconut first, then I took that out, and she climbed on the water bottle to push on the cage door and make noise. I don't know what's wrong with her but I was up most of the night till I put her in the traveling cage temporarily and set a heavy box on top of it so she couldn't push on it. But then she dumped the water dish I gave her, and started turning it over and over in the traveling cage, so I had to take that away. I don't know what's wrong with her; maybe she's lonely.
