Hi Ashley and Pepper, welcome to FDMB. You have already had great responses from members, and I just would like to add my support and say Hello!
If Pepper was dehydrated, it would help him if you add some extra water to his canned food. And smaller, more frequent meals are going to help satisfy his hunger, as most unregulated diabetic cats are very hungry because they can't utilize food as effectively.
As CandyH and Catcat suggested, the Walmart ReliOn Prime meter and strips are not expensive, nor are the lancets to make the prick to get that drop of blood to test. You can use a cotton ball, a folded tissue or paper towel to back the ear when you use the lancet, and for compressing the site to help prevent bruising. It helps to use some petroleum jelly on the ear before using the lancet to help the blood drop bead up. So, you already have some of the supplies you will need. Here is a link on home testing the blood sugar:

Even if you are fortunate enough to have Pepper go into remission on a low carbohydrate diet, with or without insulin therapy, he will always be diabetic and will need testing periodically to ensure he is still in remission, and to be able to act accordingly in time if he drops out. Knowing how to test and having the supplies on hand is going to provide the information you need.
There is great information for caregivers for newly diagnosed diabetic cats on the
Home page, the Getting Started and Education sections to the right side of the page. Knowledge is power and the more you know, the better care you can provide for Pepper.
You can create a signature that provides Pepper's information whenever you post. Just provide what information you have right now, you can edit when necessary. We also use a spreadsheet here to record any insulin and testing data, so that we can see right away what the testing numbers are, and be able to tell if the diet change is having enough effect.
1. Setting up your signature (light grey text under a post). Here's how:
click on your name in the upper right corner of this page
click on "signature" in the menu that drops down
type the following in the box that opens: kitty's name/age/date of diabetes diagnosis/insulin you're using and dosage amount /glucose meter you're using/what (s)he eats/any other meds or health issues (s)he has. You can add your name, and a geographic location (sometimes the time zone matters) Be sure to SAVE when you are finished.
2. Another thing that will help us help you when you get started BG testing at home is to set up a spreadsheet like the one we use here. You will see how the trends and patterns emerge, and members can review his/her progress before offering suggestions or advice:
