For the past few days, Lizzie has been very sick and hasn't been able to run much. On Wednesday she was panting very heavily and would sit in very unusual positions squinting her eyes, so I took her to the vet Friday morning. Apparently there is something pushing on her lung and trachea making it very hard for her to breathe. They took a couple xrays but were not sure what was causing the problems. They sent me home with some drugs to help her breathe easier, which has made her noticeably calmer and she's started to eat and drink again, but alas, we still don't know what's wrong with our poor Lizzie! If anyone has seen their hamsters experience similar symptoms and have suggestions on how to improve her condition we'd most appreciate it! Below are her xrays.
