My rat Emily, is going to die very soon. I took her to the vet today because she has a tumor just above her left front leg. She can still walk and eat and is still pretty active. The vet says that it is cancerous and it feels like a blood mass has collected there. So he tells me that one day it will pop and she'll bleed to death. It will be pretty quick and he assures me that she wont suffer. He also tells me that she's not in any pain at the moment and I don't have to put her to sleep but if she gets to a stage where she can't walk or eat then I have to bring her back. She's pretty old for a rat, she's just over 3 so she's had a long life. I just feel so bad.
