Thanks everyone for the help. Fiance tested again at 6am, and the reading was 227. I'm expecting a high reading when I test him pre-shot at noon. And I will test Nadirs today to be safe. Yesterday he ate at regular intervals, and was alert and himself, so if he dropped lower than 52, he showed no symptoms. We were trying to give his ears a rest, but too nervous not to test at Nadirs today!
Here's what's happened so far, and I'll try not to write a novel about it. (Joke--I write novels for a living) We noticed Billy was ill on the 27th. Not eating, lethargic, a little vomiting, but didn't seem in immediate trouble. Took him to vet on 28th. Vet tested blood, urine, and did xray to rule out a blockage. Sugar was over 500. Urine showed sugar and signs of a low to mid-level infection. Billy got a shot of Cerenia for nausea and a shot of Cefazolin for the infection. Vet proscribed insulin, and said give him 2 units if he ate and 1 if he didn't. Vet sent fiance and Billy home with a bag of Hill's dry prescription food. Vet said he wanted to see Billy again in two weeks. I took one look at ingredients of the Hill's, and said I was not feeding Billy that stuff. Researched online, found this site, read a ton. Bought Fancy feast. I already had a meter, (I was diagnosed diabetic a year ago, but kicked it to the curb.) Bought Billy his own stabby-stab, because I suck at doing it by hand and he doesn't mind the click. Made a rice sock and got some Vaseline.
Billy did not eat anything until evening of the 29th, and then only a few bites. Since then, appetite has been increasing daily and now he is eating more normally. We feed several smalls meals through the day, and pull up food 2 hours before dosing time. Billy loves wet food and he loves Fancy Feast, the amount he is eating has been steadily increasing, and yesterday was the first time I thought he ate a normal amount, asking for food, and sometimes cleaning his plate in one sitting. That's why we got complacent. He ate a lot yesterday, and the 52 reading shocked us.
Because of lower Nadirs on the 1st, we reduced dose to 1.5. We plan to do no more than 1 for the foreseeable future, even if he has higher numbers. Last night was scary. We had two cans of a high-carb Friskies flavor and his favorite crunchy cat treats in his emergency Hypo kit. (thanks again to this site, we were prepared.) He ate about 6 Whisker lickins treats and 1/2 can of FF Gravy lovers immediately. Over the next few hours, he had a few bites of high carb dry, about 1/3 a can of the Friskies high carb, and half a can of FF Classic. BGL climbed steadily. We probably overfed a bit, but because his appetite is only now returning to normal, he didn't overdue it. He was happy to have a little bit of everything.
Left him with some of the FF Classic, woke up at 6 AM to a clean plate. Gave no food from 10am to Noon, pretest.
Tested at noon-- 280. Yeah, it's higher, but not as high as I was expecting. Was too worried to give a full 1 unit dose. Gave him .5 instead. Didn't want to skip, but was afraid of more lows. Will test Nadirs to keep an eye on him. Appetite was awesome. Ate an entire can of FF Classic for the first time.
But now I'm wondering. Was his sugar high only because he had an infection? Is he just doing so well on FF Classic and FF Naturals that we'll have to stop Insulin? I will test Nadirs today and we'll see how he's doing. Happy for any advice. Love this site. You are all rock stars. I feel like if we'd just did as the vet said, and not been testing his sugar, Billy would have had serious trouble by now. Love our vet, but wonder how much experience he has with kitty diabetes.
