Re: um newly diagnosed
First, welcome to the site. I will reply to your immediate post, but others will also be along to provide more info once you have replied.
There are some details that need to be known before much can be said.
1. What insulin are you using.
2. What dose are you giving and what times.
3. Are you home testing and using what type of meter.
4. What type of food are you feeding.
5. How is your cat acting now, and before learning of the diabetes.
6. Where are you located, so we will know if anyone is near you and in the same time zone.
There are many other questions but that's the main ones right now.
OK for the eating question now. Diabetics likely will eat more until they are regulated as the body is not able to process the foods properly to get the nutrients needed. So, kitty does not get good stuff and thinks still hungy. Losing weight is a sign that many have - I would guess that it's related to poor processing of foods in the body among other things.
When my two were first dx, I started them on insulin and they ate like maniacs. Oliver was eating around 30oz of food a day and Shadoe not far behind with 20oz or so. I was buying food all the time and they were inhaling it!
Now, they are much better and eat less than half that amount each day.
As for what you are feeding, get rid of ALL DRY FOODS. You want to be feeding LOW CARB foods. I don't know where you are located but we usually refer to Binky's list as several foods are listed including the carb %. You basically want to go with pate types, none of the gravies as that's where the evil carbs can be found. Who told you not to change the diet and what are you feeding now? If it's some expensive vet rx food, of course the vet would say stick with that food!
here's the list if you want to look up some foods. I also included another link with feeding info.

OK now for the injection location. There is absolutely nothing wrong with injecting at the scruff of the neck. You may have been told poor circulation but all I know is that it's the most common spot and the dispersing is fine. Others may inject on the flank, the sides of the cat, but many do NOT like it. I tried ONLY ONCE on mine and she nearly took my hand off. I'll stick to the scruff. It works just fine.
You did not mention it, but it's vital for you to be home testing so that you can know how your cat is reacting to the insulin. I worry about a vet saying don't test .... if you had a diabetic child, would you just shoot insulin without knowing the child's BG? If you ask a human diabetic, they will tell you that they test themselves before giving insulin, so ... is your cat less important to keep safe? Testing may save your cat's life one day. There have been some hypo situations lately so you can read about them on the board.
Sure, your cat could look just fine, but many cats do not show signs of being hypo. You should have a HYPO kit prepared, just in case you need to use it.
Here are some links with info:

I forget what's all in this link, but there has to be something useful there for you!

So there we go.
Ask any question you have; they are all good to ask.
Please answer the above questions as not everyone has knowledge on all insulins. I have used caninsulin, Lantus, Levemir, and Humulin R, but there are others that follow entirely different protocols, so the type of insulin and the dose are very important.
Again, welcome to the site.
