We are starting the insulin injections tomorrow at 8am at the vets office. They said they will take his glucose ~every 3 hours. Last week, one of the techs told me that he should be fasting when I bring him in. But tonight I started thinking.......if they are going to be giving him the insulin and checking every three hours, wouldn't they want him to come in and start at the level he will normally be every morning (in other words - not fasting)? Did anyone else have their vet start with the shots and ask that the cat be fasting when you brought them in?
