I have a diabetic cat diagnosed about 3 months ago. He was at over 400 at the vet at that time. Started at 2 ml /mg? whatever the notches are. Next trip to vet was a 393 and upped dosage to 4. Increased about 3 weeks ago to 6. He does not seem to be doing any better. Fed this morning and a half hour later was at 547. Checked 5 hours after that and at 322. We home test at different times and will use the spreadsheet to post some numbers. He is starving all the time and just wolfs his food. We are feeding the fancy feast classic and cooked chicken, no dry food or any carbs for the last 3 months. I di pick up a new vial today so will use the new stuff and hope for better results tomorrow.
