My cat has been in the hospital for four nights. He is home now. The vet increased his insulin level from 1 unit to 2. However, I'm pretty sure he was eating Hill Science Diet for Diabetes during his stay. Now, he's home with me, and I feed him no more than 6 or 7 % carbs....usually less. I'm thinking Hill Science Diet is around 20%. The vet said his BG never hit below the mid 200s. Since he's back on his low carb food, is 2 units of insulin going to be too much?
