What is feline diabetes?

Diabetes mellitus is a very common disease found mainly in older and obese cat. The cause of feline diabetes is virtually similar to diabetes in humans. Diabetes is a disorder in which blood glucose is not utilized correctly and regulated inside the body. During digestion, glucose enters the bloodstream, and the cat’s body then releases insulin to control blood glucose levels.

If your cat is not producing any insulin, it will develop diabetes. Too much build-up of glucose due to a shortage of insulin can also be potentially dangerous. Overweight, neutered cats who eat a lot of high carbohydrate diet are more susceptible to Type II diabetes. In Type I diabetes the pancreas does not produce enough insulin resulting in high blood sugar. But this type of diabetes is rare in cats.

How Can Pet Parents Notice Diabetes in Cats?

Increased thirst and frequent urination

Lack of insulin prevents the cells from absorbing glucose, and the excess glucose in the body of your cat makes him thirsty. The kidneys filter out this excess glucose, that carries water with it, making your cat lose more water through urination.

Eating more and still losing weight

A diabetic cat cannot consume the calories it ingests as energy and so will break down fat and muscle tissue for that purpose. Cats with diabetes usually have a voracious appetite and eat a lot of food but would lose weight also at the same time.

Lethargy and weakness

The cat will have less energy if he cannot use the calories he is taking in. Your cat may become weak and lazy and lose muscle mass. Your kitty may also prefer sleeping more than playing.


Vomiting may be an indication of the waste building up in the body as the body breaks fats for energy.

Walks differently

Owing to weakness, a cat with diabetes walks flat on the back of the hind legs. Due to increased blood sugar levels, the nerves in the hind legs are affected and can also lead to complete paralysis if left untreated for long.

If you observe any of the above symptoms in your cat, call your vet who will run a laboratory test to determine how much sugar is in its blood or urine.

How do Cats Digest Carbohydrates like Grains?

Cats mainly obtain the energy they need from fats, proteins, amino acids, minerals, and vitamins. They are metabolically designed to derive energy from amino acids and fats and not starch. Due to millions of years of evolution, a cat’s body has lost its ability to produce enzymes such as hepatic glucokinase and hepatic glycogen synthetase, which are required to regulate blood sugars.

A cat’s body also produces very less pancreatic amylase, which is an enzyme that breaks down starch into glucose. In the wild, the cats would eat a starch free diet that has resulted in a lack of amylase as cats evolved as a species. Therefore, the cat is unable to get much energy from carbohydrates. Too many carbs can cause flatulence, so in some cases, low carb and low fiber cat foods are also a good alternative.

However, carbohydrates can be good for cats as they protect their muscles and also spares their muscles from being broken down for energy. Adult cats don’t need carbohydrates in their diet. But simple carb like glucose is essential, as the cells primarily use glucose for their energy needs.

Healthy cats can digest and absorb dietary carbohydrates very easily. While cats have an ancestrally high-meat diet that does not contain any carbs, only plant-based foods do, but a cat can digest plant-based carbohydrates and use it as an energy source. Carbohydrates provide cat instant energy and are beneficial. Healthy carbs like carrots, spinach, broccoli, and others are a great source of energy. Human grade cat food is also a type of cat food which contains only the best of meat and vegetables for your cat, so consider checking those types of products or even subscriptions.

Cats digest carbohydrates differently from other animals. Cats have specific disabilities regarding the digestion and absorption of carbohydrates. In cats, the metabolism of carbohydrates does not start in the mouth as they don’t have the enzyme amylase in the mouth; instead, digestion begins in the small intestine.

In cats, amylase is only found in the pancreas and chyme, but the intestinal amylase activity is quite low. But still, cats do need a diet that consists of a balance of fats, protein, and carbohydrates.

However, excess carbohydrates can result in obesity and diabetes in cats. High carbohydrate diet can also cause diarrhea, flatulence, and bloating.

Cats need a more protein-rich diet and only small amounts of carbohydrates through the food that they ingest. It is essential to give your cat food that is high in animal meats as they get the essential amino acids from them.

Amino acids create new muscle fiber, fuel other bodily processes, support healthy muscle growth and overall development. So it is crucial to maintain proper protein levels in your cat’s diet.
