My guinea pig I've noticed is losing weight. I tried to go to my vet but she is out of town so I had to go to a new hospital I've never been to before. The doctor couldn't tell me why she was losing weight. He told me to give her yogurt drops? I dont think he knew what he was talking about. I'm concerned and my original vet wont be back until November. My guinea pig is eating normally, same diet, she doesnt move from her house much. She does have a roommate. (Her daughter) can anyone help me. Her weight right now is 870ounces I think he said
