My cat is 22 years old and was sick over the weekend, got antibiotics and shes much better now and eating normally. they took blood and all her test showed fine for her normal compared to her last test, her creatine was 2.3 and BUN actually went down to 26 which was 44 in May, but her glucose which read 320, in May her yearly follow up she was around 260. Shes been on prednisolone for over a year now which I know can spike glucose from what I read and shes on it every other day, i keep her on the lowest dose I can. The Vet said he could send it in for a Fructosamine which came back and he said 294 I believe. He said its not overly high but high. Over the weekend she was sick and after hearing her glucose was 320 I switched her to fancy feast pate and she seems to be eating it just fine. I don't know if the switch in food over a few days would lower her glucose that much. He said he wanted to start her on Insulin tomorrow and after researching this like a mad women and how to manage Diabetic cats I read its good to home test. So I went out tonite and bought a home meter and saw online how to test cats on the ear. She didn't seem to mind it, got blood the first try and it read 133, this was after she ate about a hour ago. 133 I know is not really high to call for insulin. I used the meter on myself to see and it read 98 which is about normal for me. I'm just afraid to start her on Insulin being 22 years old and if shes testing this low it worries me. I spoke w/ a Clinic by phone and she said there are other test like doing a hourly at home glucose testing to see where she stands throughout the day or even getting another opinion. has anyone every delt with this or have any advice?
