I just read the entire thread (my computer was out for a couple of days). I am sorry that Myndi is losing hair and some weight. The lab results will give you and the vet a good idea of what's happening and hopefully there will be a med to help her if needed. I'll keep checking back. I just read that her lab is now set for Monday because of snow. I agree that there's no need to risk a car accident so stay inside and be safe.
