What brands of canned cat food are available in your local pet store? We can start with that information and then help you find the right foods for your cat.
What kind of foods were you feeding before the diabetes diagnosis?
What kind of insulin did the vet say he was ordering for you? There are several different types of insulin available and honestly, the best ones for a cat are the human kind - Lantus (glargine) or Levimer (detemir). These insulins are available at any human pharmacy and many cats do very well on them. So much so, that they can become diet controlled and not need insulin after a while of using it.
If you do get one of these insulins, you will also need to use human syringes - which are U100, 3/10 cc, with 1/2 unit markings are preferable.
It is important that no matter what insulin you start with, that you start with a small dose such as 1 unit or less. Also, cats need to have insulin twice a day, in 12 hour increments. If the vet tells you to shoot a higher dose or only once a day, please don't listen, as that could be a huge mistake.
Are you able to go to a human pharmacy and pick up a diabetes testing meter? Any brand will work fine. You will need:
- meter
- plenty of test strips that go with the meter
- lancets (the little push pin like things that you will use to get blood)
Also pick up
- antibiotic ointment - typically found with first aid supplies - with pain relief will be fine
- ketostix or keto-dia-stix - found with diabetic supplies - this is used to test for ketones in the urine (don't worry, we can give you tips on how to collect urine to test)

Could you give us some more information.
- What is the name of your cat?
- How was he diagnosed?
- Did the vet do a fructosamine test? or just a regular blood test?
- Any other symptoms - excessive weight loss, thirst, hunger?
- Is he walking on his hocks - meaning is your cat walking flat footed? does he need to stop and rest while walking from room to room? Is he having trouble jumping onto furniture?
If he is, then it's very possible your cat also has diabetic neuropathy. In most cases, this can be reversed, with diet, insulin and vitamin B-12 Methylcobalamin mixed into his wet food. Here is a sample of what this product is:

You should be able to find something similar locally. But please make sure you get this type of B12 as it is the only one that will help.
We will do all we can to help you and your cat through this process. There is a lot to learn, but in time it will all come together and start to make sense.
