Gastrointestinal disorders (most commonly vomiting and diarrhea) appear to be common in cats with diabetes. A study found 30% of participating cats to have some gastrointetestinal problems; the most common one was vomiting, with 50% of the GI cases reporting this as a symptom[1].
When vomiting occurs, it is possible to have dehydration and/or possible hypoglycemia[2][3]. Some of what you are basing the insulin dose on is the eaten food going through the digestive process; when it's not digested or only partly digested, you have a mismatch of food and insulin[4]. If you're having a particularly rough time with vomiting episodes, you may want to talk with your vet about decreasing the insulin a bit temporarily to avoid possible hypos until the situation with the vomiting is resolved.
