She eats either the pâté or the gravy ones (they come in a mix box).
I would recommend that you set the gravy ones aside for now. You can add them to your hypo toolkit. If a cat's BG levels drop too low, the higher carb wet foods, like those gravy ones, can help to quickly raise the BG levels to a safe level. In a newly diagnosed cat, less than one year from diagnosis, any number under 50 is considered hypo territory and needs treatment.
In case you haven't already learned about how to manage low blood glucose or a hypoglycemic event, here is a good link.
http://felinediabetes.com/FDMB/viewtopic.php?f=28&t=15887 I recommend printing this out and keeping a copy with your hypo tool kit. You do not want to be scrambling to find this document in the case of a hypo.
If you have internet access, and you think your cat's BG is too low, post on here with the subject of Possible Hypo and put the 911 icon on your post. Lots of people on here know how to treat a hypo and will help you through a hypo with testing and feeding advice. We've supported many people through this scary event.
Your other option is to get your cat to an emergency vet ASAP.
Items to include in your hypo tool kit:
1 .Several cans of high carb cat food such as the Fancy Feast gravy lovers food (several because you be squeezing out just the gravy to raise the numbers. Don't want to feed too much of the solid food because that could fill your cat up before the hypo event is over)
2. a simple sugar like karo syryp, honey or maple syrup
3. a blood glucose meter to test the blood
4. plenty of test strips at least 50 recommended.
5. And these instructions,printed out and nearby.

6. Phone number and directions to the nearest emergency 24 hour vet.
7. Credit card to pay for the vet.
8. Syringe for rectal administration of karo/other simple sugar of cat loses conciousness.
9. and last but not least A designated driver so you can keep rubbing the karo on the cats gums while you drive to the emergency vet
SYMPTOMS
Some cats may have NO symptoms whatsoever, but here are the most common ones:
MILD HYPOGLYCEMIA
Sudden ravenous hunger
Shivering
Weak or lethargic
MODERATE HYPOGLYCEMIA
Disorientation
Trouble with vision... bumps into furniture
Poor coordination, such as staggering, walking in circles or acting drunk
Changes in head or neck movements
Restlessness
Urgent meowing
Behavioral changes, such as aggressiveness
SEVERE HYPOGLYCEMIA
Convulsions or seizures
Unconsciousness
To these list of symptoms, I would add extremely dilated pupils that do not respond to light. That is the only sympton my foster cat Wink exhibited. I knew he was low by doing home testing and was able to raise his BG numbers with a simple sugar like karo or honey and some high carb food. Dry food does not digest quickly enough to raise the BG numbers so having some wet food with gravy on hand is important.
The cat shelter neglected to mention hypoglycemia to me when I took Wink home to foster. I knew the switch from high to low carb food could impact the BG numbers but it happened very quickly, being ok one day and hypo the next.
We'd rather have you be able to keep your cat safe so be sure to blood test if anything ever looks funky or your cat just isn't acting right.
