It could be lots of things! The list is endless on what could be wrong with her! I can tell you that she needs to be taken to a vet and FAST, because it sounds very serious!!! All of those symptoms that you described, are a Big Red Flag and Not Normal! Since I'm late answering this question asked 2 weeks ago, I'm hoping by the time you read this, that you would have already taken her to the vet and hoping that she's ok!
