Lisa, Insulin isn't expensive, but regulating a diabetic cat can run into $$$. Most likely the kitty is at the proper amount of insulin, but they need checkups more often than a normal cat (if there's such a thing lol)! Melissa (doolittleky) can probably clue you in better. Melissa...how did you end up with 7 diabetics? Wow, that sure keeps you busy. If I hear any more about the kitty, I'll keep all posted. Sounds like the Fancy Feast cat.
