Very true, plus it might give the depot a little boost.
That would be nice!
This is complete speculation on my part, on the way Tresiba might work in cats...
We know Tresiba forms chains, and that the insulin molecules(?) break off both ends of the chains for a timed release. Now, increasing the size of the dose probably forms a few more chains, but I think the bulk of the action is in forming
longer chains. So, the larger the dose, the greater the duration of those chains -- what Lantus and Lev users refer to as the depot. When you go to twice a day dosing, you're essentially doubling the number of chains that are active. As you increase dose size, those chains will persist for longer periods of time. For an example (not to be taken for fact!) a 1u dose might form chains active for, say, 3 days. A 2u dose might form chains that last 5-1/2 days. And a 3u dose might be forming chains that will continue releasing insulin for a week or longer. Continuing with this totally inaccurate example

, we can guess that the 1u dose forms... let's say 5 chains. (It's probably hundreds of times more than that, but math and I do not get along lol!) The 2u dose might form... 8? And the 3u dose, we'll arbitrarily call that 10. After shooting 1u for the sixth cycle, you'll have 30 chains working. On the seventh cycle, 5 chains are depleted and your 1u dose is adding 5 more, so you'll pretty much be maintaining 30 chains. Now, if we consider the 3 unit dose, by the sixth cycle you'll have 60 chains working. Instead of stabilizing there, though... by the twelfth cycle there'll be 120 chains, and you're left with no idea if the chain count is stable, or if it'll continue to build for another 2 to 3 cycles... or longer
In my mind, this is how Tresiba works, and why it's able to keep blood sugar so flat -- there's all these chains, and they're all releasing tiny amounts of insulin at a pretty stable rate. But it also highlights why I'm so afraid if a cat gets into low numbers... Skipping a 3u dose because of low numbers barely makes a dent in the number of chains active

Sam bounced
once after a skipped dose, and even that bounce was pretty minimal.
Again, all of this is strictly my personal speculation. I might be way off base

But it's what made the most sense in my mind lol! Of course, there can never be an exact number, and even for Tresiba the breakdown rate will have some variation.
+6 280
Back down to yellows.
Yay! Work that juice, Zeke!
