I believe that you can get Weruva food there (I know that
@Girlie's mom can in Australia). MC is 13-18% carb and HC would be 18+. Normal low carb (LC) food we try and feed here is up to 10%. I hope she will chime in on some foods she is using to help you on what you can get there that is LC (for variety).
I have learned that Gizmo will react (BG numbers will increase) using MC most of the time (when needed), but sometimes he has to have higher carb. Gizmo's normal, everyday food is about 3-5% carb - but remember ECID (every cat is different), you will need to learn what works for Tyler.
These are great foods for feeding when you need to get them to come up (
mid-cycle). I use the Chick Magnet. Usually a tablespoon or two (of the gravy) will bring his numbers from low (too low) up to safe number.

Notice the carb% listed
This was the most confusing thing to "learn" when I started. Now I just accept what is and trust the lists.
Here is the list that most of us use
http://catinfo.org/chart/index.php
and here is the IAMS Grain Free (not sure which one you are using).
I hope I haven't confused you too much.
For now, 130 is a good safe number. I would test at +3.5 (one hour). I am kinda confused at where you are at in the cycle but I admit I am not quite awake yet (it is just after 5am here).
