Did you and the vet discuss any kind of treatment for the tumors? When BigBilly was thought to possibly have cancer my vet had mentioned steroids as a type of chemo therapy for guinea pigs with cancer.
I realize with so many going on surgery wouldn't be an option but perhaps the steroids would help him for awhile or at least to be more comfortable and eat better/gain weight?
- GL is Just Peachy
He was in good spirits until he started being extremely floppy, and falling on his side (liver problems from anorexia from the tumor making it hard to eat + stealing all his calories) and was euthanized that morning. His poops were bright orange but he had a good appetite as far as he could actually breathe enough to eat.
