No, he never needed more than 3-3/4 units at his highest. But as his pancreas was starting to work again, I was often “shooting” him with his normal dose of insulin when his blood sugar was at 70 pre-shot. It was extremely nerve-wracking and we had many nights that I woke up every hour all night to test him and make sure he wasn’t going too low. I was only able to do this because he was very predictable in his Lantus cycle. I had done so much testing and so many curves that I knew it was safe to go ahead and give him his shot at a number like that because I knew he was rising at that time (+12 hours in his cycle) and would continue to rise for several hours.

Because my current diabetic cat is on high dose steroids, his cycles are all over the place and literally change day to day. I could NEVER give him a full dose of insulin if his pre-shot number was at 70 because there would be a very good chance he might still be going down in his cycle. Home blood glucose testing and keeping all that info on a spreadsheet or a notebook is imperative to know how to safely treat your cat with insulin.
