Welcome! And bless you for adopting two little guys, one extra sweet. Everyone here was overwhelmed and scared at first, but it turns out that the more you learn about this disease, the more confident you become. It's a disease that can be managed mostly at home and inexpensively. Here are some of the basics:
We have a very successful protocol for feline diabetes:
1. A slow, long lasting insulin. Lantus, Levemir and ProZinc are popular as they have a slow onset; they are not harsh and they are easiest to use for regulation. Humulin and Canninsulin are less popular because, in most cats, they have a rapid onset and don’t last as long. We like new diabetics to start low and go slow. That is, start at a low dose of .5 or one unit twice daily every 12 hours. And increase slowly, by .25 or .5 units as the numbers indicate.
2. A low carb, wet diet. We like to feed under 8-10% carbs. There are several food charts you can use:
Dr. Lisa’s food chart
Hobo’s Food Chart Rhiannon’s 8% and under list
Whatever food you can afford that your cat will eat in that lower range. BUT do not change over to wet until you are hometesting. With our Oliver, the switch meant an overnight change of 100 points downward. If we hadn’t been testing and had given our usual amount., he could have hypoed.
3. And most importantly, hometesting. We think cats tend to be stressed at the vet
and we know stress raises blood glucose levels. So we test our cats at home. You want to know what the number is before you give the shot to be sure the amount you are planning to give is safe. And testing midcycle will show you how the insulin is working. We use human glucometers and test on their ears or paws. Here is a video that shows you how it is done:

For vacations, some of us take the kitty along. We found cat friendly motels and vacation rentals and he become a good traveler. Sometimes the vet techs at your vets' office are looking for a little extra money and they have the expertise to test and give shots. Sometimes you can find a petsitter who specializes in pets that need extra care and medication.
I would start reading on this site, especially the threads on the Main forum on Nutrition and Health. And reading threads on this page will help you see that lots of people are scared at first but quickly become less so. Ask questions. You can do this; we would love to help!
