the king eats a little and many times. he definitely eats after the injection and after a little over 2 hours until +6If you start to see mid to higher blues, you could probably increase, but I'd hold for now as they are just low blues.
Out of curiosity, at what point in the cycles are you feeding King?
With the size of dose that King is on, his pancreas is clearing sputtering back to life. You may find it's helpful to feed him a small snack (a few tsps of LC food) around +8 or +9. That can kick in the pancreas and bring those blue preshots down to green. Note, this is a suggestion only for kitties on very low doses of insulin.
