Wow, thank you for the advice. I wish that my vet would have told me this. Tater has been on insulin for almost 3 years. He was a stray that I found 6 years ago. he had a broken leg and was so malnurished that his hair was off white and there was hardly any gray on him. Once I got him well his coat turned so beautiful... he looks like a snowshoe and he's so sweet! I hate that he has to go thru so much. just 2 months ago he had surgery for two big cancer growths on his back. he did it totally awake. he is such a great kitty. he is so sweet when I get blood from him twice a day and he's great about the insulin shots. he only has one good ear to get blood from. he must have been a tough alley cat because he's covered in scars and one ear is so bad that there is no way to get blood from it. I'm bragging too much about my baby, sorry! I just really love the big baby and I want him to feel better. Any help is greatly appreciated!!!
he is on humlin insulin. below is a chart that shows how random is count is. I just wrote a few weeks from 2 years back to now. I do check it his blood every 12 hours and give him insulin. he doens't eat that much. he eats both wet and dry and I stay away from high carbs cat food. I just don't know what to do and my vet says I'm doing everything correctly but I know that I can make him feel better. It breaks my heart when he falls asleep with his head in the water bowl.
