Some general rules when stalling (ECID):
** 50s or higher – don’t feed. The number will bump up on its own soon due to the insulin wearing off.....
** Test often (every 15-20 minutes, or at most every 30 minutes).
You want to catch the rise the minute it starts. With most of our cats, once they start to rise they will really zoom. You want to get the insulin in as soon as possible, because it will be another 2-3 hours before the insulin kicks in and you don’t want to let the cycle get too far ahead of you.
Perhaps the most important guideline in shooting low is that any time you shoot your lowest ever number, you should get a +1 and +2 to give you an idea of how the cycle will go. If the +1 is not higher than PS, or if +2 is much lower than PS, that means “pay attention” over the next few hours. Those tests will also help you become even more data ready for the next time you are presented with a low preshot reading.
