I'm new here and still figuring things out. I hope I did the spreadsheet right. (Updated link)
https://docs.google.com/spreadsheets/d/1Ty0hAf5-GgxPxpZf2VvF5eiGD8gvMyE2EtmICKgkQgg/edit?usp=sharing

Our vet started Snickers out at 5u then raised him to 6u. His glucose went up to 700 and we panicked. We stopped giving him insulin completely for a day. (We didn't tell the vet.) Then we started him on 1u.

I think we've raised his dose too quickly, but we were worried because his glucose was always so high. We're at 3.5u and I just testing him - his glucose is 693.

I really need advice.

Hi and welcome to you and Snickers.:)
Thank you for setting up your spreadsheet. Unfortunately I can’t see your spreadsheet. Did you press the share button?
Are you saying your vet started Snickers on 5 units of insulin in the beginning? That is a very large dose to start.

There are a few things you will need to do, so we can help you.
It sounds as if you are home testing the blood glucose levels...that is great. That is one of the best things you can do to keep Snickers safe.
I am attaching a link to how you can help us help you. If you could read through that and fill out your signature which will appear at the bottom of all your posts, that will give us information about Snickers so we won't have to keep asking you.
Here is the link
http://www.felinediabetes.com/FDMB/threads/new-how-you-can-help-us-help-you.216696/

If you could tell us:
  • what insulin you are using?
  • Are you giving the insulin twice a day?
  • What type of glucose meter you are using?
  • What type of food are you feeding Snickers?
  • How much does Snickers weigh?
  • Were ketones mentioned when Snickers was diagnosed.
  • Date of diagnosis
  • Any other illnesses
  • How much did you increase the dose each time....in 1 unit increments, 1/4 unit increments or 1/2 unit increments?
  • How often did you raise the dose?
This is a very knowledgeable, supportive community and we will do our best to help you.
Tell us anything else you may think is relevant......how is Snickers appetite etc.
Looking forward to hearing back from you. May we know your name please?
Bron

Thanks for the reply.

I tried a new link for the spreadsheet, I hope you can see it now.

My name is Liz. I've been awake all night with the cat so I'm not going to try and make a signature now, but I will tomorrow. I do think the vet started him out on too high of a dose, but I just don't know anymore. I'm really worried that his glucose is so high.

  • what insulin you are using?
  • Lantus
  • Are you giving the insulin twice a day?
  • Yes
  • What type of glucose meter you are using?
  • Alphatrak
  • What type of food are you feeding Snickers?
  • Dry Purina DM
  • How much does Snickers weigh?
  • 14.3 pounds
  • Were ketones mentioned when Snickers was diagnosed.
  • I don't think they tested him for that
  • Date of diagnosis
  • I will have to check, some time in January this year
  • Any other illnesses
  • Not currently. Just before this he had surgery to remove a tumor on his thyroid.
  • How much did you increase the dose each time....in 1 unit increments, 1/4 unit increments or 1/2 unit increments?
  • How often did you raise the dose?
  • For those last 2 questions - I've done things very erratically. Reading this message board I realize I've made a lot of mistakes. I think I raised his dose too fast.
 
Hi Liz! Yes I can see the SS now! Thanks.

The DM dry food you are feeding is 13% carbs so that will keep the blood sugars up higher than they need to be.
Diabetic cats need a low carb wet, canned diet with carbs under 10%. Having the carbs around 5 % is better.
It is not necessary to have a prescription diet for a diabetic cat....they are expensive and are mostly too high in carbs, and the content of the food is not any better than most canned food you can buy over the counter.
Dry food is very bad for cats. It is not only high carb, it is much lower in moisture, around 7% compared to 78% for canned food. Cats need lots of moisture for their kidneys and general health.

Here is a link to suitable foods. I'm not sure what country you live in so I will give you a choice so you can pick. Hopefully your country is listed.
If you transition over to a low carb diet you should see some lowering of the numbers.
However you need to do it slowly and test frequently as the BGs could drop up to 100 points.

Lantus is a great insulin for cats, but it likes consistsncy. It is a depot insulin, which means it leaves part of its dose in the body to be used later and it takes up to 6 cycles for the depot to fill. Chopping and changing the dose messes with the depot and the BG numbers.
Depending on what dosing methods you choose, we recommend holding the dose for 3 days (tight regulation) or 7 days (SLGS). You can read about the dosing methods at the top of the Lantus page in the yellow stickies and choose the one that suits you better. I would recommend you choose a method to follow as you will get better results.

We also recommend only increasing the dose I/4 unit increments at a time so we don't go past the best dose.
Always test before every shot to make sure it is safe to give the shot.

We all make mistakes so don't beat yourself up about it. You were trying your best after getting bad advice from the vet about the dose.

I think the first thing you should do is look for some suitable low carb wet foods and start transitioning over to them slowly over about a week or 10 days. You will need to be testing frequently during this time and adjusting the insulin dose if needed.
If you post each day and keep the SS up to date, we can help you with that.
We also recommend giving several smaller meals during the day and night. A meal preshot, then a snack around +2 or 3 and another snack around +4 or 5 each cycle. A timed auto feeder is a great investment.

Then after you have swapped over to a fully low carb diet, we can see how Snickers is going and decide what needs to be looked at next. It's best to only do one thing at a time. How does that sound?

Welcome. This is the best place for you and Snickers.

So with dry food you will be following this method of dosing SLGS.

A very good start to helping Snickers is to get rid of the dry food. HOWEVER, do not do it cold turkey. Start reducing amount and introducing wet food in its place. Glucose will come down significantly when dry food is gone. You will need to monitor closely while doing so.

I will pop back tonight, have to go to work. Others will be along.
 
Thanks for the advice. I'm so scared because his glucose is so high. It was 704 just now.

We did try giving him wet food, but after a few days his glucose was really high. The vet thought he might be overeating.

I'm on my phone right now, I will post again later when I can use my computer.

Hi Liz, and welcome to you and your kitty (what is his/her name?)
Bron and Paula gave you excellent advice. When you are able to get your kitty off the dry food you will begin to see some success in getting the blood-glucose numbers down. In the meantime, it is very important to dose Lantus consistently because of the Lantus "depot" that gets established in the cat's body and that will help in getting the cat regulated. The depot is the reason we make changes in dose by only 1/4 unit at a time, and why we do not jump around in dose. You can read about it in the "stickies" (informational posts) at the beginning of this forum. When you make quick changes in dose the depot never gets a chance to allow Lantus to work the way it should. Every time you make a change in dose you have to give the new dose enough time to settle in. Since at present you are feeding dry food and dry food will still be given in lower and lower quantities during the transition to wet food, you will be following the SLGS method of dosing: hold the dose for 7 days and do a curve once a week. Once you have made the switch to wet food, you have a choice of staying with the SLGS method or switching to the TR protocol ("Tight Regulation'). You can read about both methods in the "stickies".
You will find that Dr. Lisa Pierson's discussion of feline nutrition is a good place to begin learning about wet food suitable for diabetic cats. Her excellent chart of the protein, fat, carbohydrate, and phosphorous content of most of the canned foods is a lifesaver.

Good luck on this new "adventure"! It all seems overwhelming at first, but it works.

p.s. My cat "Stu" was overdosed by his vet, who raised him by a full unit every week. Poor Stu crashed and that's when I found this group. We are here to help because we all want the best for your kitty.
 
Liz -

Not all canned foods are low carb. This is a list of canned foods. There is a column with the % carbohydrates. As Bron noted, less than 10% carb is what we consider low carb. Most people here feed their cat about 5%, give or take. Many people feed their cats Fancy Feast Classics which is a pate style food. There are other more expensive foods that are low carb or that are not pate style. I would get some varieties that you think Snickers will like and give them a try.

It looks like you have been adjusting Snickers' dose based on your pre-shot number. With Lantus, the dose is based on the lowest number in the cycle. It takes abut 5 - 7 days for the initial dose to form the depot and once the depot has stabilized, any time you alter a dose, it takes 3 days/6 cycles for the depot to re-stabilize. If you change the dose at each shot time, the depot never has a chance to catch up with your dose.

I know those high numbers are hard to see. Most of us don't know how long our kitty has been diabetic when they are first diagnosed. As a result, your cat's body may have become used to being in high numbers. These high numbers become the new "normal.' Even smaller drops into the 400s may cause Snicker's body to over-react and bounce into those ugly black numbers.
