His numbers look pretty flat but are generally in good ranges. We think that the renal threshold (the range where the pancreas can heal) is somewhere under 250 or so, so the majority of time spent there is a positive sign.
I see two difference approaches. Some get the basics and then we don't see them on the forum for a couple months. They come back after a month or so of steady safe doses And the cat has started to drop and they are adjusting the dose down. The other approach is to be more aggressive. With Bubba's numbers, you could up the dose on pinks to 1.25 and leave the dose on yellow at one for a few days. See if that makes a differnce. Be sure to get nadirs so you know how the insulin is working.
If he is eating too close to test time in the am, you might invest in an automatic feeder. It would provide a snack (in your case with more than one cat, they'd probably have to share) and will closes 2 hours before testing time. Our PetSafe5 has that capacity and is the only one I have found that he can't break into.
Bobbi, if you want, you could post over in The PZi forum for dosing questions. Health is a great place for general health, feeding etc questions, but you can get specific dose suggestions there, and see how others are dealing with their numbers.
