Hi HopeforDuffy: Please post the type of insulin you are using and your vet's recommended starting dose. My cat uses Lantus and it must be administered twice a day (shots 12 hours apart), so evening-only shots will not work with that particular insulin. I do not know about other insulins, but the senior members here will chime in shortly on that. They will also tell you to eliminate the dry food and feed only wet food. Some cats do not need insulin at all, once dry food is removed. Dry food is typically high carbohydrate, which elevates blood sugar. Here is an excerpt from veterinarian Dr. Lisa Pierson's (a feline diabetes expert) excellent article on the subject (entire article can be found here:
http://www.catinfo.org/?link=felinediabetes )
-----------------------------
"Many cats that are in a diabetic state no longer need any insulin when they are finally fed an appropriate low-carbohydrate diet. Others will always need some insulin but the amount necessary to maintain proper blood glucose levels is nearly always significantly reduced once the patient is on a low carbohydrate diet. Please re-read the previous two paragraphs carefully. If you change your diabetic cat's diet to one with lower carbohydrates, he will, in all probability, IMMEDIATELY (not days or weeks later) require a reduction in his insulin dosage. He may also immediately go into 'remission' and not need any insulin at all. If this warning is ignored, you may very well end up with a cat in a hypoglycemic crisis (dangerously low blood sugar) which can result in death, or brain damage.
Also from the same article:
"Unless the patient's clinical signs warrant immediate insulin administration, I try a diet change - with no insulin - for 5-7 days to see what impact the new diet will have on the blood glucose. In most cases, I do not agree with waiting much longer than a week to start insulin. This is because you will have the best chance of getting your cat into remission (cease needing insulin) if both diet and insulin are used very early on. The longer your cat's body is under the effects of glucose toxicity, the more his body will be damaged and the less chance of remission he will have."

Not trying to scare you, but you will hear this over and over and over again on this board - that dry food spikes blood sugar and should be eliminated. I can't tell you why some vets, even those with many, many years experience do not seem to know this, but it is not uncommon. As someone else pointed out in another post, vets are trained to treat everything from snakes to birds to lizards -- and can't be expert in every disease in every animal. For diabetes, I think that it helps to have a specialist -- or at least a vet who is up on current protocols. In the end, it is best to read all the research yourself and decide what makes the most sense to you.
The injections should be relatively easy to administer. They take all of 1 minute. The cat doesn't feel them (believe it or not), and within a day or two you will feel like a pro at this. It takes more time to brush my teeth than to give my cat an injection (I typically give them to her while she is eating, and she doesn't even look up). No kidding. My hands were shaking on the first couple shots, but my cat was busy eating. LOL!! On the other hand, the blood glucose testing (ear pricking) may well take practice and patience. It has taken a month for my cat to sit still for this, to where I am (most of the time) getting readings; though I think I am at the far extreme on this. Most people master it sooner than that. I don't think it hurts the cat much, but it does sting a little and they have to get used to it. The important thing is to keep trying, and for the cat to associate the ear prick with getting a treat. The best advice I got was to try a couple of times, treat and let the cat go -- so as not to traumatize them by sticking their ear over and over and over in one sitting. Others may have different approaches. Within a few weeks the cat's ear actually begins to bleed more readily -- those on the board say that the ear "learns how to bleed" by growing additional capillaries (?). I have found that to be true.
Best of luck to you! I am sure you and Duff will be fine, and within a month this will become an "everyday thing" for you. Post if you have additional questions.
