This is all new to me..

Hello everyone, my kitty was just diagnosed with Feline Diabetes on Friday, yesterday. Her name is Gracie and she is about 6 years old. She weighs 10 lbs, down 1.5 lbs since her last vet visit. She has always been active and social. I noticed that she was drinking a lot and peeing a lot, so I scheduled an appointment with our vet. I actually have 2 cats, Allie and Gracie. They are from the same litter, Allie is not showing any signs of illness.
So, I will be meeting with the vet next week to discuss a game plan.
I don't even know what questions to ask?? Any help would be appreciated.
Thanks

A 2025 guideline to cat diabetes that you can read and discuss with your vet about treatment for your cat: 2025 iCatCare consensus guidelines on the diagnosis and management of diabetes mellitus in cats

Not all vets are knowledgable with feline diabetes. Many newbies have come to this board with very little information provided by the vet. Sometimes they're given a poor insulin choice and a bag od prescription dry food and sent on their way with no other info. It's ok to get a new vet if you don't feel the current vet is very knowledgable.

The basics to ask:

What insulin will the cat be started on and what dose? Lantus and ProZinc are the best choices to use. No more than 1 unit twice a day is the recommend starting dose. Better to start too low and not see any effect than to start too high and risk a hypo. If the vet insists on a larger dose, be firm and say no.

If the vet suggests the newer treatments like Bexacat or Senvelgo, think about it first before making a decision. There's info here: Info - New Treatments for Feline Diabetes

Diet - Big one. Ignore the vet if they recommend prescription food. There's nothing in prescription food that helps diabetic cat. Save your money and buy low carb canned food instead. The food charts are here: Links to FOOD CHARTS Any canned foo under 10% carbs is best. Brands like Fancy Feast Classic / Gourmet pates, Tiki Cat, and Weruva are good. Your other cat can also eat the same food. Don't feed any dry food. Dry food keeps blood glucose levels too high. Home cooked and raw diets are also options some people choose to feed. Start the low carb diet before you start insulin. Doing both at the same time can be tricky because there's a possibility of a hypo if you're not closely monitoring blood glucose levels.

Blood glucose testing - Some vets encourage it, others don't. Monitoring levels daily is important just like it is for Human diabetics. You can manually test from the edge of the ear or from a paw pad. It may take awhile and a lot of patience and low carb treats to get a cat used to testing. All you need is a Human blood glucose meter and supplies. Pet meters do exist but they're pricey and not sold in stores. For cats with ear problems of some sort or really spicy cats, a CGM is an option if expensive. There are pros and cons to using a CGM. A con, besides the price, is that the meter needs to be replaced every 2 weeks, sooner if it falls off or malfunctions (very common). Most people who use a CGM here replace the meter themselves instead of paying the vet $$ to do it. You need to know how to manually test from the ear or paw pad as a back up. Discuss testing options with the vet.

Blood glucose curves - Since you'll be monitoring levels at home, you can do a curve yourself instead of paying the vet $$ to do one that won't be accurate. Stressed out cats spending the day at the vet will have super high blood glucose levels.

This post may help with interviewing a vet.

A few basics to get you started.

Insulin: There are only two insulins that are recommended by the American Animal Hospital Assn for the treatment of feline diabetes. They are either Lantus (glargine) or Prozinc. Lantus is now available as a generic/biosimilar and is a human insulin or Prozinc which was developed for animals. There are other insulins that vets will prescribe (e.g., Caninsulin) but it is not as long acting as the other recommended insulins and it tends to act fast and drop blood glucose numbers rather abruptly. If your vet recommends something other than Prozinc or Lantus push for either of those insulins.

Food: Many vets will recommend a "prescription" diabetic food. The pet food manufacturers have done a very good job of pushing these foods. The problem is that there is nothing in a prescription diabetic food that is actually "prescription." In fact, the pet food companies lost a class action lawsuit due to their misinformation. Rather, what is important is that just like a human diabetic, cats need to be on a low carbohydrate diet. Unfortunately, the cat food manufacturers don't put that information on the can. Go figure!! This is a chart that has nutritional information including the carbs in most of the canned foods available in the US. Canned food is preferred over kibble. Most of the dry food that's available is outrageously high in carbs. We consider low carb as under 10%. However, most of the members here feed their cat a variety that's around 5% carb. You will want to have some medium carb (10 - 14%) and high carb (over 15%) food on hand in case you need to bump up numbers should Gracie's numbers drop into a lower range.

Home testing: We strongly recommend that you learn how to test your cat's blood glucose. There are both glucometers that are developed for pets although it's fine to use a human meter. Many of the members here use the Walmart Relion meter because the strips are considerably less expensive than those for a pet meter (Relion is about 17 cents per strip vs $1.00 per strip for a pet meter.) Home testing is the best, if not the only way to ensure that your cat is in safe numbers and it allow you to gauge her progress. It will also allow you to make dose changes and you can do curves at home rather than have your cat spend a day at the vet's office and cost you a small fortune to have the vet do the curve. Also, most cat's blood glucose numbers are artificially elevated at the vet's office due to stress so you really don't get an accurate picture when your cat is tested at the vet's office. Frankly, if your vet is of the opinion that it's not necessary for you to test at home, ignore the vet. Most professional organizations support home testing but there are vets who will tell you that your cat will "hate" you if you test. I've been here a long time and there are only a very few cats who couldn't adjust to being tested at home. There are now continuous glucose monitors available (i.e., there's a sensor that's attached to your cat and replaced every 2 weeks) that's an alternative to poking your cat. You can also share your test results with your vet.

Helping us to help you: this is a post that goes over some of the basics. It also has information for setting up a spreadsheet so you can track Gracie's blood glucose levels as she makes progress. There's also information on setting up your signature. This will provide some information about the insulin you're using, date of diagnosis, etc. so we don't keep pestering you with the same questions.

I'm hoping that a newer member will stop by and fill you in on what was helpful in getting started. There is a whole section of FAQs and links that you may want to review. The amount of information at the beginning of this journey is overwhelming so please, don't hesitate to ask questions. The members here are very generous with their time and knowledge.
