Hi Everyone my nine year old baby Humphrey was diagnosed in October last year, he is on Lantus 3 units twice a day. His last glucose curve at the vets was still very high and instead of spending more money to have them do it again I decided to try it at home. He is on the Purina Pro Plan DM diabetic dry cat food, half cup in the morning, a half cup in the evening. He got his food this morning around 8am and I did his first reading at 9:15 (It was my first time took me awhile to get a good sample!) that was 183. I gave him, his insulin shot and then I retested him at 12:15 (I thought it was every 3 hours eeekk I'm new at this!) It was 379!! I feel sad for my little guy, I don't know how his sugar jumped that high in 3 hours...I'm going to keep testing him through the day. I want to get him feeling better and I feel lost. Any help would be greatly appreciated.
