Hello everyone, I'm new here to the forums and hope some of you have advice for me. In November my 14 year old male cat was diagnosed with diabetes. We started out at 1 unit in the morning and night and I went back to the vet a week later to have his blood sugar tested again. It was in the 500s. So the vet raised the dose to 2 units in the morning and night and I went back the following week to have his blood sugar tested again. Once again he was in the 500s and didn't seem to be responding at all. The vet said maybe the cat being stressed on the ride to the clinic caused his levels to spike, but he proceeded to raise it again. I think he bumped it up to 4 units twice a day and on the following check up his blood sugar was a little lower I think in the 400s but still way to high. Anyway, this kept going on until reaching 7 units. The cat still isn't responding at all so I took him to the vet today and they're running a glucose curve and seeing if he's responding at all. The vet called and said things aren't looking well and the cat isn't responding very well. He said he got the sugars down to the 300s but said that was still way too high. I'm at my wits end and the vet is suggesting to put the cat down. I really don't want to lose my cat as I've had him since I was 4 years old and am really attached to him. I'm worried the cat is suffering and I really don't want him to suffer any longer. I'm hoping maybe you guys can suggest something more I can do to try and save my cat. Please give me any advice that could help, I really appreciate it. Thanks in advance, Brad EDIT: I guess i've left out some details. My cat LOVES his wet food and I have no problem getting him to eat. He has lost a lot of weight due to the diabetes but doesn't look too unhealthy. The cat urinates a lot and fills up the cat box in a day and I have to empty it almost completely to clean it. This has not got any better since starting his insulin injections. I have been using ProZinc insulin. Thanks for your time.
