Hi Rebecca & welcome!
You'll see that most of us post a new thread daily with updates on our sugarcats... everything from BG level and dosage, to the more minor details; food, ketone checks, fluids, etc. It's always overwhelming when you're first getting started, but it does get easier. I had the biggest difficulty getting Grayson to bleed enough for the tests. He's still not a good bleeder, but my skills have improved, and his ear is somewhat more cooperative!
You'll see a lot of shared wisdom here, as well as people that do things a little differently. TID (3 shots a day), a sliding scale (varying doses depending on the preshot) different shooting schedules 14/10 vs 12/12, different needles, and small or large doses... Note that those of use who do these things got here VERY SLOWLY, and only after much testing and analyzing. The rule of thumb is "Start low and go slow." Starting at 1 unit every 12 hours is a good place to start. We generally recommend holding the dose for a while so the kitty can settle into the dose. When we do an increase, it's usually by 1/4 or .2u.
By keeping a spreadsheet of Juno's numbers, as most of us do, you can update Juno's numbers, and we can all view your spreadsheet to see where you've been and advise you on some things you may wish to try. It's also a great tool to look at the other people's spreadsheets here... (there's a link in the bottom of our posts - each time you update, it automatically updates the spreadsheet for you!) so you can realize that you're not alone in this "dance". Most likely, one or more of us has been where you are - no matter WHAT comes up! Feel free to ask lots of questions. There's usually a fair number of people around throughout the day, so you can usually find help when you need it. We also use the "Preshot" +number" system. Since we're often in different time zones and on different shooting schedules, using the time can be confusing. So we list our am/pm preshot number (AMPS/PMPS), which gives us a baseline. Then each test we do after that is based on the preshot. So if I shoot at 3 pm, then 5 pm becomes +2; 8 pm becomes +5, etc. If we miss a shot, because kitty is too low to shoot (usually in the beginning, that's below 200 or 250), we continue counting; 3 am is +12, 6 am is +15. Then when we finally shoot, it restarts the clock again and we start w/ +1. Some of us have had kitties that "dance" on a dose for as much as 24 hours. That usually results in a reduced dose, but for kitties on the verge of going into remission "OTJ" (for Off the Juice!), they get reduced doses until they no longer need insulin.
Lots of info to digest - I won't overwhelm you too much this time. But feel free to ask questions and someone is usually along shortly to respond.
Again, welcome to "the dance"!
