About a week ago I rescued my third piggy from the animal shelter, and ever since then she has been having some medical problems. I have been using the same things they had her in while she was at the shelter so I didn't know if that could be it. But she is not really eating well or drinking water. She doesn't seem very happy. And she hardly comes out of her little hiding spot. And as of yesterday she is now having diarrhea! But when she is not having diarrhea she is not doing anything at all. Her cage is still spotless. I have no idea what to do. And I do not want to lose her! Please help!
