Can you get her on rats? It might be a hunger issue even though she's eating 2 to 4 mice at a time. Doesn't explain the soaking but that could be due to a bit of dehydration. Some BPs can get a bit snarky as they age. It could be anything from she doesn't like a certain hide to your curtain was open slightly. You said you had her a year. She might be getting to the I want a boyfriend stage.
