Diabetes in cats

Diabetes Mellitus is a serious and complex disease. And sadly, it isn’t uncommon in cats. Between 0.2 and 1 percent of cats in the general population are believed to suffer from diabetes.

Diabetes affects the hormone insulin. This is a condition in which the body cannot properly produce or respond to the hormone insulin. This results in elevated blood sugar levels.

The Cornell Feline Health Center tells us that the cells in a cat’s body need sugar in the form of glucose for energy. Blood glucose needs insulin because insulin signals when the time is right to absorb glucose. By absorbing glucose, cells get the vital fuel they need and lower levels of glucose in the blood.

Although experts are yet to find all the possible causes, carbohydrates could be a culprit. Low carb cat food diets designed to manage feline diabetes are the preferred option. It’s also a great choice for helping to slim down obese cats.

If your goal is diabetic remission, it’s important that you consider diet as a way to safely treat your cat’s diabetes.

Clinical signs of diabetes in cats

  • Weight loss
  • Increased urination
  • Increased thirst
  • Loss of appetite
  • Decreased energy levels. Your cat may not show the same interest in playing or climbing their cat tree.
  • Vomiting
  • Dehydration

This disease can ultimately lead to a coma or even death in severe cases.

Obese cats are at an increased risk of getting feline diabetes. If you notice any of these signs or other behavioral changes, consult your vet!

Dog & Cat Diseases : Signs of Feline Diabetes

What is the best cat food for diabetic cats?

One of the first steps to treating diabetes in cats is transitioning them to cat food that has a lower carbohydrate content.

This is because carbs break down into glucose. More carbs mean more glucose, which will need more insulin to keep BG levels regulated.

According to Catinfo.org, “In the wild, your cat would be eating a high protein, high-moisture, meat/organ-based diet, with a moderate level of fat and with only approximately 1-2 percent of her diet consisting of carbohydrates.”

The best food for overweight cats or cats with diabetes is high in quality protein but low in carbohydrates. Most canned cat foods are low in carbs, making them the ideal choice. Yet not all cats want to eat low carb wet food.

If your cat’s condition is severe, your vet may recommend a prescription diet or an all canned-food diet

Does your cat need a low carb diet?

Diabetic cats aren’t the only kitties who can benefit from eating low carb cat food. Obese cats, indoor cats with low energy expenditures, and cats with food sensitivities also do better.

High protein foods actually suit your cat’s natural nutrient requirement better than high-carb diets. As obligate carnivores, cats need high protein amounts in their diet.

Some cat parents opt to feed raw cat food because it most closely resembles what a cat would eat in the wild.

What is low carb cat food?

A low carb cat food is considered to have a percentage of up to 12 percent carbohydrate. Always read the label and check the ingredients on the back.

Ingredients that are red flags include meat by-products or organs that have been deemed “unfit for human consumption.”

Having said this, pretty much all organs aren’t considered fit for human consumption in the US, but they can still be very nutritious. The main point is that organs coming from a high-quality chicken are healthier than muscle meat from a sick chicken. But it is difficult to determine the quality of the organs from most ingredients lists. Avoid high carbohydrate grains like corn, wheat, rice, or soy.

Ingredients that should be included and that you want to see listed first are muscle meat like chicken or poultry. You should look for protein from a named meat or poultry source, taurine, and other vitamins, minerals, enzymes, and fatty acids.

In many cat foods, carbohydrates generally include grains, but also legumes, and potatoes. All these contain starch, which may cause weight gain. Although your cat can digest such components, they simply don’t need them to stay healthy.

Is dry cat food high in carbs?

Dry food manufacturers need starch (which is full of carbs) to bind the kibble. Some amounts of starch are necessary to make dry cat food. According to PetMD.com, for some individuals, canned food is far superior.

“The dry food contains almost three times the amount of sugars and starches in comparison to the canned food.”

Some cat foods have as much as 35 percent carbs! Be sure to check out the carbohydrate percentage on the label of your cat’s food.

Pet owners are demanding both low carb wet cat food and low carb dry cat food. Some cats have a preference!

What dry cat food has the lowest carbs?

There are many low carb dry cat foods. Some brands worth checking out include:

However, canned grain free cat food is the lowest in carbohydrates. The moisture content is also higher and mimics a cat’s natural diet.

Choosing the best low carb cat food

Choosing a new food for your cat isn’t easy.

Brand Reputation

With cat food, you always want to check the brand’s reputation in food forums and with your local pet store staff.

Sadly, not all pet food brands are trustworthy. Some commercial cat food brands use questionable ingredients, or, produce low quality food.

We recommend checking out consumer reviews as well as for any potential recalls. If you’re interested in having this information readily available then check the American Veterinary Medical Association.

Ingredients and nutritional analysis

With low carb cat food, dry or wet, meat should be the first ingredient on the list. This shows that it’s high protein cat food.

Looking at cat food labels can be confusing! The AAFCO now has guidelines on what brands must include and what claims they can’t make.

  • Always read the cat food label: There is a system for listing the ingredients on your cat’s food label, and understanding it will help you pick the best ingredients.
  • The FDA mandates that ingredients must be listed from most to least based on their weight.
  • The majority of your cat’s food is made from the first few ingredients listed, so be sure they aren’t fillers. Instead, look for whole foods.

Animal protein and fat are crucial ingredients that should be included in your cat’s food. Because your cat is an obligate carnivore, it needs nutrients like taurine.

However, if your feline friend has diabetes, we recommend asking your vet about the best choices.

As a rule of thumb, there should be around 50 to 60- percent crude protein and only up to 12 percent carbohydrates in your kitty’s food.

If you want some help, we recommend checking out the AAFCO nutrient profiles. Here, it shows the recommended percentages.

Choosing a Healthy Cat Food

Carbs or no carbs?

Low carb cat food is ideal for obese cats and cats with diabetes. Your feline friend isn’t made to break down carbohydrates, which may contribute to obesity, diabetes, and other potential health issues.

Making sure your cat is getting all the nutrients they need PLUS staying at a healthy weight is key to long-term success.

Fortunately, there are plenty of low carbohydrate diet options on the market. Today, our favorite is the Weruva Grain-Free Natural Canned Wet Cat Food. It has a high protein count, offers balanced nutrition, including vital amino acids like taurine, and is moisture-rich making sure your cat stays lean AND hydrated.
