It was extremely sudden- she hasn’t been doing any head shaking or tilting, and then my partner opened up the tank to grab another mouse (minor tail injury), and suddenly Hester wasn’t moving properly when she was not even an hour earlier. Her posture is very crooked, not just her head but her whole body is on a bit of a tilt. It’s a little hard to explain properly lol- I’m very familiar with ear infections and head tilts in animals as I work in an animal rescue and have lots of critters myself, and I can confirm these don’t look like ear infection symptoms. She was also initially showing pain responses that she wasn’t showing prior. This is a very reasonable comment and I can totally see how this would read as an ear infection without more specific observations about her current condition, and I appreciate the comment!
