My 11-yr-old cat was recently diagnosed with diabetes (Dec 18) and hasn’t been responding well to insulin. I’m using a Lantus pen and he started on 1 unit after his blood sugars were tested at 500. A week later they were down to 400, so he got upped to 2 units. Two weeks later, he’s lost over two lbs in total and his blood sugar is still around 400. He’s eating and drinking, but clearly uncomfortable. He has been upped to 3 units on the Lantus. I also worry because he has stomatitis and it’s flared up over the past month and seems to be causing him more pain. The vet says we can’t do a teeth cleaning when he’s not regulated. I’ve bought the alphatrak monitor and will get it tomorrow to start home testing. I’m not sure what to do and the vet isn’t sure either. Is it possible to get BG numbers that are too high with a too high insulin number? Also should I be using the pen as is or getting a syringe? Stuck and worried. My vet initiated the “quality of life” conversation yesterday and I am worried he’s uncomfortable and in pain!
