Glad you got a good vet report yesterday and that she is feeling good today.
With what has happened with us, I am of the mind that some kitties, like Asher, need a longer time to show you what they want to do on a PZ dose.
My vibe is that Kitty will need more insulin at some point but its good to see what this dose is gonna do for sure before you move it again.
Good day and good numbers to you!
