Hey Sondra,
Glad to hear things are going better for you guys.
1) As for "celery sticks" to fill them up between meals, I wonder if he might like Pure Bites freeze dried chicken breast treats. I buy the bags marketed to DOGS because they are larger chunks and they are much cheaper than the same thing marketed to cats. It is 100% chicken breast, therefore high protein, (low carb) and minimal in the calorie department. You can either wet it and it looks like raw chix, or you can crumble it onto food to entice them to eat (sounds like that is not an issue :lol: ). I do both to add some high quality protein to his diet. I think the bag says something like 8 calories per treat, but each piece is a different size so ????? If you have a Pet Supplies Plus nearby, they sell them.
2) I noticed you said he is a BIG kitty and now you are up to 3u. If you end up getting to 5u someday, you might want to come give us a look over in the HIGH DOSE insulin support group forum. Big (ie large paws, big head, big organs, pot belly,) and resistant to high doses, can be clues to some other explanations about his diabetes. How old is he?
3) My cat used to be desperate for food and did much better with more frequent meals. As mentioned above, you don't need to change the overall amount, but break it up into possibly 4 meals/day rather than 2 meals/day. I think it actually helps a recovering pancreas to have more frequent meals. If you work or aren't home a timed feeder is a perfect solution. Here's the new link to Pet Safe feeders. (Cody broke into the 2 meal feeder, so I would splurge for the 5 meal feeder. )

It looks like you home test a little bit. Is he difficult to test? It would tell you so much more about whats REALLY happening if you could do a curve at home some weekend. Curves at the vet (car trip) are stressful and usually less accurate (and very expensive) If your strips are expensive, there are really good meters available with strips as cheap as $16.50 /50. Here's one option that I use and feel is very consistant.
