You might want to read this when you are not tired from work. And since you got a +2, don't get a before bed. Just call it a night on the testing and save your strips.
To answer your question, first, you find out when they are diving. My guess is that Tashie is dropping early....+2/+3 timeframe maybe?
When you have a kitty that does that, you "frontload" the feeding. If you know how many calories Tashie gets per day, divide it into two (two cycles, right). Many cats respond well to feeding at PS, +1, +2, +3.
Example: Tashie gets 4 oz of food per cycle (I'm, obviously making this up). If you feed her at PS, +1, +2, +3, then you would feed her 1 oz at each feeding. OR, you might find, as I did with Gracie when she was on lantus, that feeding her a larger portion at PS and +1 and smaller ones at +2, +3 works. The idea is to have food on board when the insulin kicks in at +2.
Manage the curve with food---->flatten the curve----->adjust the dose (if necessary).
How do you do this if you work? An auto feeder....many members use them. How will Tashie adjust? Well, before FD, I free fed Gracie. Whenever she walked in the kitchen and squawked, she got a small portion of food and we did this all day and evening until her total portion was done. She adjusted just fine to the switch. In fact for quite some time now, if I don't have her food ready ON TIME, she is letting me know. She knows exactly when she is supposed to eat.
A couple caveats: it can take time to see a change and you might have to mess with it to find the schedule that works best for Tashie because she hid her "caregiver's manual" right?
