I have a cat Rosco that was diagnosed with diabetes, I am doing his curve testing today because we are at the 7 to 10 day stretch of his insulin, I wanted to know why when I tested him at 6 this morning his reading was 389 but then when I tested him 3 hours later it jumped all the way to 700, I thought the insulin was suppose to make his blood sugar go down, 700 is the highest reading he has ever had, when I tested him two days into starting his insulin it went from 550 to 430, will I get lower reading as the day goes on?
 
We need more info to be able to answer your question. Such as what insulin is he on and what dose, what kind of food are you feeding, what meter are you using.

if you’re willing to setup a spreadsheet, we can help you with dosing advice too.

He's on md or dm food from the vet im using alpha track 3 monitor and his insulin is Lantus
 
I don’t have experience with pet meters, but I think the numbers are generally higher than what we get with a human meter.

I believe both of those foods are too high carb for a diabetic cat. Tagging a few others here @Sienne and Gabby (GA) @Bron and Sheba (GA). You don’t need expensive prescription foods which are actually lower quality than most regular food out there. Most of us feed Fancy Feast or Friskies pates as they’re low carb.

Unfortunately most vets do not know a lot about feline diabetes….they have many animals to look after and they all have different diseases and treatments. Vets also get their information about nutrition from the big cat food manufacturers so they are biased in what they recommend.

With a diabetic cat you need:

  • A low carb wet diet that is 10% carbs or under. Most of us use around 4-7% carbs
  • A suitable insulin such as Lantus or Prozinc which are long acting, more gentle insulins than the old insulins. Lantus is a great insulin with well done there!
  • We recommend hometesting the blood glucose with a human meter…it is not necessary to use a pet meter which is expensive to run and is no better. It will keep your kitty safe and you will know how the dose is working for your kitty. Only testing every so often will not tell you what is happening in between those times and an awful lot can happen in even a day.
  • HELP US HELP YOU has information about the spreadsheet, signature and hypo box which you will need to be able to look after your beloved kitty properly

We are happy to help you with setting up the spreadsheet, sorting out what food to buy, how to transition safely to a low carb diet, how to learn to home test and much more.


FOOD CHART have a look on this chart and choose foods that are under 10%.

You will also need some higher carb foods for that hypo box..information in the help us help you link.

This is an excellent site for diabetic cats…it has been around for more than 25 years and has very experienced people to help you.

Keep asking lots of questions!
 
Welcome to FDMB.

There can be a variety of reasons for Roscoe's numbers to jump. First, is the DM or MD canned or dry food? If the latter, both varieties are very high in carbohydrates and can drive numbers up.

Numbers can sometimes do what we refer to as a "bounce." If Roscoe's numbers dropped to a lower level, sometimes a cat's liver and pancreas will overreact by releasing a stored form of glucose along with counterregulatory hormones that cause numbers to spike. Without seeing more test data, there's no way to be sure if this is what happened this morning.

I'd encourage you to get a spreadsheet set up. With Lantus, you want to be testing before every shot time and get at least one test during both the AM and PM cycles. The more we are able to look at how Roscoe is responding to insulin, the more we can help.
