how is it with TR that you can increase after 3 days? Isn't that conflicting?
Yes, which is why we suggest you don't belong to more than one Facebook group for feline diabetes.
TR has been proven to work and even been published in a veterinary journal. Yes, it's an aggressive protocol but it's also the best chance you can give them to reach remission (but requires feeding a canned or raw diet).
Many of the Admins/Mods in that other group you're in originally learned how to care for their own cat here. I don't know why they have changed their advice to holding each dose that long but it's not necessary and can encourage glucose toxicity to set it (where even though you're giving insulin, the body gets used to being high and you end up having to give even more to "break through" the toxicity)
Have you ever tried to figure out what causes his IBD problems? It can take time, but usually the best place to start is with a novel protein....a protein source he's never eaten before like rabbit, lamb, quail, bison, pork or kangaroo. Budesonide is also a medication that can work well in IBD without causing the problems that other steroids do (usually...ECID)
There's some Facebook groups for IBD too.
Raw Feeding for IBD cats and
IBD Kitties are two I recommend.
The only time it is important to hold the dose for 5-7 days is when you first start so that the depot has time to build. After that, depending on the dosing method you use, you can either hold each dose a full 7 days (SLGS) or do TR which allows more frequent dose changes.
Is it important to test every day mid-cycle?
In my opinion, yes, it's important because the 1 time you don't, you might miss a test that explains crazy numbers in the next few cycles. If he doesn't complain, what makes it so exhausting?
