I live in Maplewood,Mn... My robo dwarf hamster Lola is about 1.5 years old,she has no other hamsters in the cage with her. About a 1 or 2 weeks ago I noticed that on her lower stomach she has like a big bump there. And today I walked in my room and looked in the cage and she was like upside down having problems like twitching and stuff, so I flipped her back over and she was sort of fine. She wobbled and stuff. I'm very scared and I think she might die soon. What is the bump and is she feeling any pain and what can I do to help? :(:(
