you avoid hypos by frequent testing and learning how your cat responds....but even then, there are occasions when they might go too low (under 68 on the AT)....by testing often though, you see that they're going too low and can intervene to bring them back up with high carb food or Karo/honey/syrup
Yes there are occasions when you wouldn't shoot...if your cat isn't eating at all or they're lower than you're used to and you can't be home to test
What we do is withhold food for the 2 hours immediately before shot time so we get a test that's not influenced by food....then we test/feed/shoot
Test to make sure they're high enough to give insulin (this number will vary depending on the protocol you use, your ability to test and your comfort level),
Feed to make sure they're at least willing to eat and
Shoot
Each time they drop below 68 (on the AT) they earn a reduction in dose.....the hope is that they keep earning reductions until they "earn" their way off insulin completely
If you want to see the benefits of learning to shoot low, please take a look at China's spreadsheet in our signature.
It would really help if we could see the numbers you're getting on our spreadsheet program. We could give you much better advise then. Here are
