Lantus is a wonderful insulin for cats with very high remission rates! I've personally helped treat three cats with Lantus (the first of which was my Bandit :smile: ), and all three are in remission and doing great! I would say that Bandit is healthier today than he was
before his diabetes because the the diet change to canned food only, so I am completely in shock that the vet would tell you most treatment is unsuccessful in cats. I'm sorry, but that's a red flag to me with that vet and I probably wouldn't get advice about diabetes treatment from him. When the correct treatment is followed (a slow acting insulin like Lantus or Levemir, proper dose adjustments according to the Lantus/Lev dosing protocol and home testing, and a low carb, canned diet), the large majority of newly diagnosed cats go into remission.
If you need suggestions for low carb, canned foods there a TON in many different price ranges. Fancy Feast classics are really popular here because they are easy to find and most cats love them. Here's a link to the diabetic safe flavors:

Ok, so now for some info. As Carl said, shots are incredibly easy. I gave Bandit his insulin injection while he was eating, and I don't think he ever once even realized he was getting a shot! You'll want to get .3cc, 5/16" (8mm), 30-31g needles with
half unit markings. The half unit markings are important because dose adjustments for cats are made in .25u-.5u increments. You'll need a glucose meter--any human meter that takes a small sample of blood (.3-.6 microliters) is good--the Relion meters from Walmart are very popular here because they are good quality and they have inexpensive test strips, which is a very important factor in selecting a meter because you'll need to be testing Pudgy's blood multiple times a day.
Testing is a little difficult at first, but after a week or two you'll be a pro, even if your cats starts with a fight. Some cats are fine with it right away, but a few do need some patience. Nearly all cats come around and tolerate testing after a few weeks. The key is using a larger lancet so you can easily get a drop of blood (26g works well), and giving a low carb treat (100% Freeze dried chicken or salmon treats from the dog or cat treat section at the pet food store are very popular) after every test. Bandit was horrid and fought me tooth and nail the first week, and I had to wrap him in a blanket with just his head showing and put him in a basket to test him. Today, he comes running to me when he hears the meter beep on, lies down, and starts purring while I'm testing. It's amazing what treats can do!
Cats have very few nerve endings in the tips of their ears (less than people do in their fingertips), so it does not hurt them to poke and get the drop of blood. What they hate (and is why they struggle) is being restrained, and having something new and strange done to them by their scared and nervous human. Once you are no longer nervous about testing and the cat accepts the routine, everything works out just fine.
I'm attaching a couple articles or both you and your vet. I would print this material out and give it to him, and read it over yourself. Because your vet does not seem to be up to date with feline diabetes treatment, I would strongly recommend seeking dosing advice here in
the Lantus forum, since cats in DKA need more aggressive dosing. To do that, you'll need to set up a spreadsheet for Pudgy's home test numbers that you'll start collecting when he gets home. Instructions for that are here:

Also check out the stickys in the Lantus forum, because there is a wealth of information there.
Here are the AAHA diabetes guidelines:
http://www.aahanet.org/PublicDocuments/AAHADiabetesGuidelines.pdf
Note p. 218, where it states "Home monitoring of BG is ideal and strongly encouraged to obtain the most accurate interpretation of glucose relative to clinical signs. Most owners are able to learn to do this with a little encouragement, and interpretation of glucose results is much easier for the clinician."
This is the article about the lantus dosing protocol which has an 84% remission rate in newly diagnosed cats:
And the dosing protocol itself:
