Hi and Welcome,
Great job on getting the SS up and running. Hope you will find some time to read through the info in the stickies, please ask any questions if you are unsure of anything, no such thing as a stupid question
With regards to TR, if you decide that you would like to go for this option, it is more aggressive, but will get kitty into normal numbers more quickly than SLGS, if you hope for remission, getting kitty into a normal range quickly gives you the best chance of remission (it can happen on SLGS, we have seen it on the board, but it is less common). And even if you dare not hope for remission (I didn't when I first joined, was afraid to jinx George), having high BG is very hard on their general health, especially the kidneys, that was one of the reasons I opted for TR.
All that said, please note that they would both have to be off the dry food altogether to follow TR, one of the prerequisites is that they are on a low carb canned or raw food diet.
I took a look at both sets of numbers.
On the surface it does 'appear' that Ninja is doing better. Many cats have lower BG's at night, and after looking at both SS I would suggest a couple of things regarding testing for both Ninja and Shinobi.
1) Always test before you give an insulin shot, It's really a matter of safety, I've seen kitties go from red midcycle to green at PS. If you are shooting Green, it may be necessary to make adjustments to feeding, and you would want to be sure you had enough supplies on hand to manage the numbers should you need to, as well as time to monitor (with lantus we usually test, feed and then shoot if for some reason you were surprised by a lower than usual number, don't feed, and post for help before shooting)
2) Regardless of which dosing method you decide to follow, data is key to help you make the right dosing choices for your kitties (Is that ninja in the avatar? Cutie pie). With that in mind, I would recommend always getting a test before you shoot, then another couple of tests in each cycle, (am and pm) Kitties can have very different cycles am and pm, George went through a phase where he was high at night and low during the day, then another phase where he was high in the day and low at night (the latter played havoc with my sleep) So in the pm cycle, if nothing else get at least a before bed test. I worked on 7am/7pm schedule and as I usually go to bed at midnightish that allowed me to get a +4/+5.
