Feline Diabetes
Did you know that cats can get diabetes, just like humans?
It’s true!
Like for us, the most common type of feline diabetes is diabetes mellitus, also known as type 2 diabetes.
And just as is the case with us humans, many owners can manage cat diabetes successfully via a careful diet.
Of course, for any animal the ideal situation is to remain disease free.
But when a diabetic condition is properly managed, cats can enjoy a normal lifespan.
What causes feline diabetes?
Type 2 diabetes is the most common form of feline diabetes and occurs when the body does not use insulin properly.
This type was once called adult-onset diabetes, and diet and exercise play big factors in its onset.
Both genetic and environmental issues have a part to play in feline Type 2 diabetes.
The high prevalance of diabetes among Burmese cats suggests this breed has a genetic predisposition to the disease.
Environmental risk factors are:
- old age
- obesity
- being male
- being neutered
- receiving some drug treatments
- physical inactivity
- and indoor confinement.
Sadly, as is the case with the incidence of Type 2 diabetes in humans, experts have also seen a worrying increase in Type 2 diabetes in felines.
In contrast, Type I diabetes (once called juvenile diabetes) is a result of the pancreas not producing enough insulin.
This type is the result of an autoimmune disease.
In both forms of diabetes, dangerously high blood glucose/sugar levels occur as a result of the body’s faulty response to insulin.
Managing cat diabetes
My own adorable black tabby cat was diagnosed with diabetes 5 years ago.
It was startling to hear that he had such a serious condition.
But with medication and a diet recommended by his vet, Fuzzy is now doing fine.
In fact he’s going strong at 12 ½ years old, and there’s no end in sight to his natural feline curiosity and enthusiasm for life.
If your cat is diagnosed with diabetes, you should know that there are things you can do to help manage her condition, including introducing diabetic cat food into her diet.
Choosing the best food for diabetic cats
Over 80% of diabetic cats are believed to have Type 2 diabetes, which requires both medication and nutritional management.
In many cases, changes in diet alone are an effective tool against diabetes.
Lots of cats do not require medication after switching to a low carbohydrate diet.
A diet high in carbohydrates increases blood glucose and insulin levels.
This increases the risk of both obesity and diabetes in cats.
This is why many experts view a low carbohydrate/low fiber/high-protein diet as potentially helpful in preventing or managing diabetes in cats.
So, do we have you wondering about the best cat food for diabetic cats? Good!
That’s because we’re going to review some of the best food for diabetic cat diets.
Before we look at some of the best best dry cat food for diabetic cats and wet food for diabetic cats, let’s take a closer look why they work.
Diabetic feline nutritional needs
Cats are obligate carnivores and their ancestors survived on a high protein diet with minimal carbohydrates.
In contrast, modern, manufactured cat foods commonly contain lower proportions of protein and increased amounts of carbohydrates. Why is this?
In a word, the simple answer is economics. Carbohydrates are a less expensive and easier-to-source ingredient than protein.
The result is a commercial cat food market filled with a variety of high carb/low protein foods.
We’re going to help you find a dry or canned food that is high in protein and low in carbs.
This type of diet minimizes blood sugar spikes after eating.

Portion control for diabetic cats
Another important part of feeding a diabetic cat is portion control.
Obesity is closely linked to diabetes, so maintaining a healthy weight is an excellent line of defence.
At your cat’s next check up, ask your vet what a healthy weight range is for their breed, sex and age.
You can also talk about an appropriate daily calorie intake based on these factors, your pet’s level of physical activity, and whether they go outdoors or not.
What should pet owners feed diabetic cats?
Several studies have shown that a low-carbohydrate, low fiber, high-protein diet improved insulin sensitivity in cats.
Other studies have shown that supplements such as taurine might belong on a diabetic cat food list.
Taurine is an amino acid which appears to improve the symptoms of diabetes, possibly by the way it supports cellular functions.
Always consult your vet when considering a change in diet for diabetic cats.
Our reviews include Royal Canin diabetic cat food, Purina diabetic cat food, and Hill’s diabetic cat food, as well as other specialized brands .
Ask your vets advice about which might be most suitable for your cat, and how to transition them over to it.
Dry food for diabetic cats
Dry diabetic cat food is more convenient, and in some cases more economical, than wet or canned food.
There are many reasons to provide a dry food to your cat, including the fact that some cats simply prefer it!
In addition, the dry bits have the ability to gently scrape away troublesome tartar and plaque from kitty teeth.
However, animal fats and proteins by themselves simply aren’t dry substances.
So to “dry them out” dry diabetic cat foods inevitably contain some carbohydrates.
In this respect, diabetic dry cat foods offer a diet lower in carbohydrate and fiber than mainstream products, but not exactly low by any objective standard.
They might be suitable for a cat with only the early signs of diabetes, or a cat losing weight to avoid diabetes.
Discuss this further with your vet.
Meanwhile, here are some great dry diabetic cat food choices.

Best diabetic cat food
So, what is the best diabetic cat food for your cat?
We need to remember to concentrate on what causes diabetes in cats.
Diabetes mellitus occurs when high blood sugar/glucose levels remain elevated due to the body’s insufficient response to insulin or a lack of insulin.
In other words, carbohydrate metabolism is a key factor behind diabetes.
A diet low in carbs reduces the amount of insulin needed while maintaining more even levels of blood sugar intensities.
In many cases, diet alone can be an effective tool against diabetes, with many cats not requiring medication after switching to a low carbohydrate diet.
You can also protect your kitty by mitigating against other risk factors such as obesity and inactivity.

What do you recommend for a diabetic cat who has lost too much weight after being on low-carb food since diagnosis? My cat’s blood sugar is controlled and he is in diabetic remission but has lost too mich weight to the point where his bones are sticking out a bit. He has always been big so seeing him like this is worrying. How do I continue to manage his diabetes while ensuring his weight is stable and not too low? It seems like most diabetic cat food is aimed at weight loss but then what to do once the cat reaches the desired weight?
My insulin dependent cat is fed 2 cans of grain free canned cat food a day. We also give her dry in between meals -only Zero Mature which is made for diabetics. She’s 17 years old and doing great with diabetes! I was shocked to learn she’s a diabetic since I’ve been taking insulin for 50 years!
She’s maintained her weight for one year. She had lost weight at the time of her diagnosis.
After reading through everything, I did not find the carb count for any of these foods. Is there someplace to find that? Many don’t list it in the analasis which is odd because it’s crucial.
I also don’t understand the need for a prescription. These foods are good for all cats.
Any food Guaranteed Analysis has: Protein, Fat, Fiber, Moister, in percentage. It has to be 100% in Total. So, subtract from 100 protein, fat, fiber, moister, and ash (if available you will get carbs.
Grocery store canned cat food pate is fine, vet didn’t recommend any special food. My cat has been eating Fancy Feast pate for 5 yrs and she’s been doing great without insulin
my cat has been diagnosed as borderline diabetic. i have found, through a LOT of label reading, that as long as you stick with any brand of cat food that is pate you should be fine. do avoid most treats unless they are the pure dried turkey, chicken, etc.
My cat – anywhere at 12-15 years, picked at a shelter – has been on insulin (3 units – 2X a day) for about 4 years I guess, and I have been feeding her Prescription Diet m/d canned food (glucose and weight management) and the same brand of dry food for a few years and she has been doing quite well. Probably because people complain about the high cost of prescription diets, if I want the canned m/d now, I have to call in and have them order a case. The dry… well they didn’t have any in stock today. Now they recommend Purina DM Dietetic : I have a hard time with the idea of changing something that works well and for the Purina brand, which is a Nestlé product and I avoid ALL Nestlé products. I got a can of the Dietetic to try with her, but I know she’ll eat anything, except that I don’t want to give her just anything. Any advice?
I just bought 2 cases of hills prescription diet urinary care c/d for my cat with problems with urinary tract infections and before he had any he was diagnosed with diabetes. Is this cat food ok to give him with his diabetes?
My cat was diagnosed Feb. 2018 when she was almost 19. At that age we decided against insulin and changed her diet. She had eaten Friskies canned food up till then. After MUCH research, I switched her to Purina DM wet, then alternating meals with Simply Nourish Essentials Indoor Tuna, and Tuna in a Savoury Broth. She turned 20 last month and is doing amazing, after many times last year we thought she wasn’t going to make it. I am now searching for alternatives, as she seems bored with these now. She has gone from an overweight 18lbs, to 9 lbs now, but she’s happy and still looks pretty good.
Finding this very helpful Lynette, as my cat as just been diagnosed with diabetes she’s 18 and was very active until now with a good appetite she had Sheba pouches, will try out the ones you recommended, how is your cat now. Thank you
The stray I found at work was a diabetic. That way why she was dumped. She was about 18 months when diagnosed She eats fancy feast classic pate and purina dm dry cat food. It works for her now. Have noticed she is having lows. Bought a meter off of Amazon. I am hoping with her being young her
pancrease will repsir itself. She is on insulin.2 shots a day 4 units.
My 17 year old cat has just been diagnosed with diabetes in March 2020. She is on 0,1ml insulin twice a day. I put her on Royal Canin Diabetic Dry food and Royal Canin Wet food straight away. She has 1//2 packet of the wet food with a few dry food in the morning and evening. If she is hungry during the day then I will give her a very few dry food.
As far as using the sandtray, she does about 7 wees during the day and about 2 poos. I do find that she does get constipated, so I have to give her laxapet.
Please could you advise if this sounds like the norm for diabetic cats.
