When we came home from the vet I had the Lantus script and m/d cans and dry. I started the insulin at 1u and fed Gobi the m/d only. The insulin was slowly raised to 3u. After 3 months of the m/d he hated and the Lantus he was still the same and lethargic. The vet switched him to Humulin N and said to continue with the m/d can and dry. Gobi stopped eating the m/d and I resumed the FF. I need help in understanding how to take his readings. I know how to take his blood from the ear flap, but I need to know the times of day and how long after the insulin is given. I need the schedule. Also if he is fed only cans, is he allowed to be free fed? I am very concerned with his weight. Getting off the dry will not be a problem for Gobi. He loves the canned food, I think he went to the dry food just to check it out, because he would take 2 or 3 pieces and walk away. He will do that with any dry food.
If you weren't home testing and basing the dose adjustments off those numbers, and if he was eating high carb food, then the Lantus was not being dosed properly and that's why you didn't have very good results (although without home testing, you really don't know if it was working well or not--3u is a pretty high dose for a cat and very likely too much insulin, and too much insulin keeps blood glucose levels just as high as too little insulin). You might want to give it another chance using the right dosing protocol, or perhaps Levemir, which works very similar Lantus. You definitely want to get a script as soon as you can for something other than the Humulin N--it is ineffective in cats and it's very unlikely you'll see any improvements while using that insulin. Prozinc would also be a better choice.
Unfortunately, even the canned M/D is not good for a diabetic cat--it's about 14% carbs (you want less than 10%), and contains corn starch, which will keep his blood glucose levels high. There are higher quality, cheaper alternatives you can feed your cats than the prescription diets (Hills charges an arm and a leg for those foods but uses the cheapest filler ingredients they can find, which is why many cats don't like it). Here's a link to the cat food nutrition chart:
http://catinfo.org/docs/Food Chart Public 9-22-12.pdf. You can pick anything under 10% in the "carbs" column. The suggestion to feed a high calorie food to help him put some weight on is a good one--
Wellness (the grain free flavors) foods are high in calories, as are
EVO, and you can get both in big cans which makes it far less expensive than what you're paying for the Hills, and they are much better quality foods and low in carbs. If you have an independently owned pet supply or feed store in your town, they are going to be much cheaper there than at Petsmart or Petco.
If he likes Fancy Feast and you are ok with continuing to feed that, here's a link to the diabetic safe flavors:
http://www.felinediabetes.com/glutenfree.htm. Considering his age, I would personally go with one of the Wellness or EVO (if he'll eat them--first priority is finding a food that he likes and will actively eat) because of the higher quality ingredients and higher calorie levels. Plus, it's cheaper to feed those foods than Fancy Feast if you buy it in the 5.5oz or 12-13oz cans, if you want to feed it to all your cats. I would get a couple small cans first to see what he likes best, though. And yes, you can absolutely free feed canned food. Just add some extra water to keep it from drying out. You can leave it out for up to 6 hours if you add some water, or 12 hours if you freeze it and leave it out.
Here's a link that tells you how to create a spreadsheet, which will help you chart the numbers you're taking at home:
http://www.felinediabetes.com/FDMB/viewtopic.php?f=6&t=18207. If you need help understanding it, don't hesitate to ask! Once you set this up, there are many experienced people here that can give you advice on how to adjust the insulin dose. With any insulin, you want to aim to test at least 3 times a day (before each shot and a mid-cycle check to see how the insulin is working).
I don't have any personal experience using Humulin N, so I don't feel comfortable giving you dosing advice with that insulin. Again, my suggestion would be to change insulins as soon as possible to either Lantus, Levemir, or Prozinc, as these are the recommended insulins for cats. If your vet won't write you a script for a different insulin, I would find another vet who will. Most vets are cooperative if you ask and are firm about it, though.
