Re: Bud's #s are all over the place....
Wow, you are in Costa Rica! I'm sure it is beautiful, you'll have to tell us or share pictures when you return!
It's pretty hard to tell what's going on for Bud Bud without any nadir numbers, but from the 89 at +7 on the 18th, I wonder if maybe her dose needs lower just a little, maybe to .8U or so. Do you think Kara could do that? Does she have access to the board?
Bud Bud's increased activity could result in lower numbers from higher energy output or if she is not eating as much when she is outside. If she eats more when inside, then it's probably the latter or combination of both.
It does sound like she's doing good and although the higher numbers are worrisome, your caregiver sounds on top of it. I hope you're enjoying your trip!
Food and insulin are a balancing act. Some cats do better if free fed. It might be good to try to give her food at regular intervals, rather than free fed. I'm not sure how you would plan to do that, since you're away and have someone sitting (is Kara there only twice a day or can she be there more often?), but a timed feeder might be the best option. You can get them with 2 spots for food or 5 spots. The 5 spot ones are expensive, but I love mine and highly recommend them. It's on sale at Amazon

I hesitate to recommend that particular brand because of the review I read saying how easy it was for a cat to open and if you have a smart cat like Gandalf, that could be a problem. The one I use, the CatMate 50, doesn't get any better reviews, actually gets worse, but my experience with it is that Gandalf has NEVER been able to open it, although he even got it upside down once when he was uncontrolled and starving for food. He noses at the lid and if it's close to the time for it to open, it will, so he's learned that. He is not scared by it because there is no motor to turn the dish, he hears it snap when it goes off and he knows to check it. My worst incidents with it are actually operator error, when I forget to set the timer....
All in all, it does not seem like there is the perfect feeder, but the Pet safe one is cheaper and I have read others here on the board use it and love it, so that one is probably the most used.
