Hi - I am awaiting Baby's IGF-1 and IAA test results of which I'm pretty certain she will have one or both conditions. SRT/surgery are not in the cards, unfortunately, so I am praying to hear some success stories (not necessarily that your high-dose kitties went OTJ, but that you WERE able to stabilize them below the renal threshold (230-250 on a human meter?) without doing any other treatments besides insulin. How old is/was your kitty when diagnosed? How high a dose of Lantus/Levemir did you eventually get to, and then how low when finally stabilized below renal threshold (and how long did it take)? Did you have to supplement with R insulin ever? Could you share your spreadsheet with me to show my vet? Thanks to all! I love this forum and members! You guys are the best!
