Small meals spread apart are good, and easier on a healing pancreas. How you feed your cat depends a bit on their eating habits. Neko was a hoover, some people have grazers. If I put something down, it was gone in 40 seconds (or less - I timed her). So I used an autofeeder to spread out about 3 meals in the first part of the cycle, and she got another small snack around +9, which was closer to her nadir on Levemir. Ideally you don't want to feed carbs after nadir. At that point, the insulin effect is starting to fade. Adding carbs makes it wear off faster, shortening duration and giving you higher preshots. I found the autofeeder had a second benefit, she stared at it instead of me for more food.
Shooter is currently "training" you to give him more food more often. Try to resist.

You also need to control the amounts. If you don't already, get an ideal weight for him from the vet. Weigh him once a week or so, and see if what you are feeding him is getting him towards your goal, be in weight loss, gain, or stable. The amount you need to feed varies by cat, their weight, age, and activity level. More information on
