My hamster's eye is shut with pus and her bottom is wet. What's wrong?

Updated on September 23rd, 2025

Pet's info: Small Animal | Unknown - Small Animal | Female

Hi! I received a hamster as a gift for Christmas and I should have done more research before getting her. One of her eyes looks like it's shut completely and there was pus on it. She also looks like she peed on herself and her bottom is very dirty. I can't clean it because she's nippy and I can't get her still.. I was hoping you'd be able to help me out!!

Poor Hagrid! Her eye issues can be caused by an infection, and may be painful. The soiling on her bottom is likely caused by diarrhea, which can be extremely dangerous in hamsters as they can become dehydrated quickly and even die. Diarrhea can be caused by rapid diet change, intestinal parasites, or bacterial infections. You should have Hagrid seen by a veterinary as soon as possible, as she may need antibiotics for her and stabilization. In the meantime, you can provide moistened pellets for her on the cage floor so that she can easily access food and water. I hope all is well!
