Thank you so much everyone for your positive thoughts and sweet words. Sydney is doing pretty well right now. I had to go out of town this weekend to help my boyfriend move to another city, and my mom was in charge of taking care of Sydney. Apparently she has been eating a lot because my parents have told me that she has been eating everything in sight. She is acting a lot better as well - I would say she is acting like her normal self - she is running around the house, with her tail up, and her eyes as bright as they can be. She is throwing up, which is a side effect of the hyperthyroidism, but other than that she is much better. I need to talk to the vet further - but for now, Sydney needs to just put on weight. The hyperthyoidism is going to have to wait until she is at a healthy weight. Keep up the postive thoughts - she again is doing well - that is my little fighter ;-).
