Hi
Sorry but I'm in the UK and hope you don't mind me asking for advice???
Our beautiful Katy whose 12 was diagnosed last month. The first time we took her to the vets her blood was 18.5mmol, he told us not to worry about testing her blood. Caninsulin was started at 1ml morning and night. A week later back we went and it was 25.7mmol,( insulin raised to 2ml) this time he said that she needed hard cat food and is on Hills W/D and normal wetfood (Sheba trays) He also said that we should test her urine and sold us a kit of plastic littertray beads, pipette and siringe. Of course she didn't use the tray that had the litter in and off we went to the vets for her weekly check up, blood was tested and it was 26.6mmol. (insulin raised to 3ml). We brought a human blood monitor but couldn't get blood from her ear. This week her blood was 26.4mmol. We have just finally managed to test her ourselves and her blood was 24.4mmol, she's due insulin in 5 hours (she's currently on 4ml).
She's also been drinking less in the last week, was 350ml, then 200ml and now 100ml daily. But she seems fine in herself and is playing and is far brighter this last week than she has been in a while
Should we take her off the dry food????, im totally confused and scared as we have no kids and shes my baby
Any advice would be appreciated
Many thanks
Welcome to the site!
I guess the first thing I would say is that you should stop the dry food; it's not good for diabetics, and any vet who says a cat 'needs dry food', especially a diabetic does not know much about feline diabetes.
Feeding Your Cat: Know The Basics of Feline Nutrition
Of course you should be home testing. If you had a child, you would NEVER give insulin shots without first testing the BG... ask any human diabetic and they will think you are nuts to say they dont' need to test their BG. You want to know how well your Katy is doing, and if possible, once she is eating a good low carb wet diet, she may not need insulin! Without testing at home, you will never know. The numbers at the vet are most often off because of stress, and the numbers you get at home will be true because Katy is in her own home and relaxed.
I don't know which blood glucose meters are available to you, but Bayer and OneTouch are a couple that I like. The FreeStyle meters have been found to give false readings for cats, so that's about the only one to be avoided. What meter did you get for testing? Keep at the testing because it will let you know how Katy is really doing on the insulin.

There is a conversion you can use:

18.5 and 25.7 equate to 333 and 463
Now, Caninsulin is not the most long lasting insulin, but I know it's hard for people to convince vets in your area to use other insulins. You may be fine with the Caninsulin, but if not, you may want to talk to your vet about using Lantus or Levemir. For now though, you can see how the Caninsulin works for Katy.
I would not raise that dose any higher until you are testing and getting some numbers.... also, when you stop feeding that dry food, you will likely need to give her less insulin.
some info on insulins and their lasting :
Duration is the length of time an insulin continues to lower blood glucose.
The four duration categories are:
* Rapid-acting or Fast-acting insulin begins to work shortly after injection, peaks in about 1 hour, and continue to work for 2 to 4 hours.
* Regular or Short-acting insulin reaches the bloodstream 30 minutes to an hour after injection, peaks anywhere from 2 to 3 hours after injection, and is effective for approximately 6-8 hours.
* Intermediate-acting insulin generally reaches the bloodstream about 1-2 hours after injection, and is effective for about 8 to 12 hours.
* Long-acting insulin generally reaches the bloodstream about 2 to 4 hours after injection, peaks 4 to 8 hours later and is effective for about 12 to 18 hours.
Note that an insulin that is long-acting in humans may be intermediate-acting in cats. The duration classes used here are for humans and usually match those in dogs -- their classifications in cats are somewhat shorter due to cats' faster metabolism.
Intermediate insulins (Lente) are insulins like Vetsulin (
Caninsulin) and NPH, some of the human insulins have N in thier name (Humalin N) although some vets are still prescribing them they are becoming less used. Espcially since Vetsulin has been taken off the market in many countries. The more successes with long acting insulins have encouraged many vets to avoid these once typical insulins. Many are however still used with good results in dogs with diabetes (dogs have a metabolism more like humans and these insulins work much longer for them) the animal approved insulin
(Vetsulin, in Europe/Canada sold as Caninsulin) was made primarily for dogs.
Long-acting insulins are the synthetic analogs such as
Lantus and
Levemir. PZI and Prozinc are simular to these however thier duration is often somewhat shorter putting them "in between" intermediate and long-acting. Several other long acting insulins are no longer manufactured (Ultratard, Humalin U)
Caninsulin does not usually last the full 12hours, so it would be important to have you testing Katy and see how long it's lasting for her.
NOTE: Increasing the dose will do nothing to make the insulin last longer. The higher dose will only force her numbers much lower but for the same 8 or 10hours, and then her numbers will rise again.
