I did drop her off by 9:00am and later the vet called me and told me that her sugar was 350 so that he wanted to postpone her surgery by a day and give her some insulin to bring it down, so she stayed at the vets and the next day he called me to tell me that he had given her four units of insulin and she had dropped into the 40 - 50 range, I can't remember the exact number. So anyways, to make a long story short, she ended up staying at the vets for three days and nights, she had some kind of urinary infection as well, and had her tail amputated. She has been through a whole lot recently, and I cant' help but wonder if the high bg tests at the vets were due to stress (being away from home) and the fact that she will not eat a bite of food the entire time she has to stay at the vets, the pain her tail had been causing her, and the urinary infection all at once.
