Diabetes mellitus (DM) in cats can be a serious condition and is often fatal. Many cats with diabetes have an average life expectancy of only five years after diagnosis. Because treatment is so important, it is important to be aware of the signs that may indicate diabetes in your cat.

Early on, you may notice increased thirst and urination, but these symptoms will worsen over time. You may also notice weight loss, excessive hunger and/or thirst, depression or lethargy, vomiting, diarrhea or constipation, increased blood glucose levels (hyperglycemia), increased urine glucose levels (polyuria), excessive thirst or urination (polydipsia and polyuria), inflammation of the gums (gingivitis), changes in vision (retinopathy) or changes in behavior.

The answer to this question depends on many factors, including the type of diabetes that your cat has, how well you can control its blood sugar levels, and whether or not your cat is receiving treatment for other diseases. Untreated diabetes in cats can lead to blindness, kidney failure, heart disease, and difficulty breathing. The average lifespan of a cat with diabetes is about half that of a healthy cat. However, if your cat is receiving treatment for the disease and managing its blood glucose levels effectively, it could live anywhere between 10-20 years.

How Long Can A Cat Live With Diabetes Untreated

Untreated diabetes can have devastating effects on a cat’s health. It can cause wasting and coma. Other symptoms include frequent urination, thirst, and kidney failure. Ignoring these symptoms can lead to dehydration and worsen the condition. So, it is wise to treat your cat’s diabetes as soon as you notice them. The longer you leave it untreated, the more likely your cat will develop complications.

Untreated diabetes causes wasting

Although diabetes can be fatal, it can also be treated. This disease, which affects the cat’s carbohydrate metabolism, can be controlled with an appropriate diet and medication. Treatment involves giving insulin to the cat once or twice a day. Oral medications are also available to promote insulin secretion, but they may not be as effective for diabetic cats.

Cats with untreated diabetes lose weight because they can’t use glucose in the blood to fuel their bodies. Instead, they turn to fat and protein stores for energy. As a result, they often have decreased muscle mass. The cat may also develop ketoacidosis, a dangerous condition that can cause coma.

Diabetes can also lead to a variety of symptoms in a cat, including lethargy, a weak back leg, and a plantigrade gait. If left untreated, this disease can lead to ketoacidosis, dehydration, and even death.

Diabetes mellitus is a common condition that affects cats. The pancreas secretes insulin, which regulates blood glucose levels. Without insulin, glucose isn’t able to be used as energy. Instead, the cat’s body uses fat and protein stores instead of glucose. This is a dangerous situation for the cat, and it’s vital to diagnose it immediately.

Diabetic cats can be treated with insulin therapy. The cat will be given insulin injections under the skin every 12 hours. Although many people are uncomfortable about the idea of giving insulin to their cats, injections in cats are well tolerated. The amount of insulin needed for treatment is determined by the severity of the condition. A veterinarian will develop a treatment plan that is best suited for your cat.

The symptoms of diabetes in cats are often difficult to recognize. There are other conditions that can cause the same symptoms. A few of these can include urinary tract infections, overactive thyroid glands, and kidney diseases. If you suspect that your cat has diabetes, you should visit a veterinarian for a thorough examination and blood tests. Typically, glucose will be elevated in the blood and in the urine.


Diabetic ketoacidosis can be fatal to a cat, and the first step is to treat the condition before it becomes a serious problem. The condition is caused by too little insulin, and the body starts wasting away. This can lead to coma and eventually death. Luckily, there are treatments for diabetic ketoacidosis that can be administered at home.

The signs of diabetes in a cat include sudden loss of weight, excessive urination, and lack of appetite. Diabetes is a result of the body’s inability to use glucose for energy. A blood test for blood glucose levels can give a good indication if your cat has diabetes. A urine test can also detect ketone bodies.

If your cat does develop diabetes, your veterinarian will be able to prescribe an insulin dosage that will keep the disease under control. A cat’s insulin dosage will change over time, depending on the results of intermittent blood tests and urine sugar measurements. It will also depend on the cat’s response to therapy. Once diagnosed, diabetes in cats is curable, but if left untreated, it can cause nerve damage and death.

Diabetes in cats can cause a high glucose level in the blood, which overwhelms the kidneys’ ability to filter it. The resulting concentration of glucose in the urine can cause dehydration. Moreover, untreated diabetic cats can develop nerve damage in their hind limbs. This condition isn’t painful, but will usually go away when the condition is treated.

Diabetes in cats is a complicated disease, with many complications. In some cases, the condition will progress rapidly, leading to organ failure and death in a matter of days. In other cases, the disease may remain stable for months and even years. In any case, untreated diabetes will eventually lead to an untimely death.

Kidney disease

Kidney disease in cats is a serious health condition that affects the kidneys. Cats with this disease can have a short or long life span. Early detection and treatment can extend the cat’s life. It is important to monitor your cat closely for any signs of kidney disease.

In severe cases, kidney failure may lead to uremia, a condition in which the cat has a large amount of waste products in its blood. This condition requires intensive hospital care. If not treated, kidney failure may lead to death. Chronic kidney disease will often require euthanasia.

Cats with kidney failure may begin drinking more water and trying to urinate more frequently than usual. They may also become lethargic and eat less. They may also have an arched back. Chronic kidney disease can progress over years or decades and eventually lead to total kidney failure.

Diagnosing kidney disease in cats requires a complete examination with blood and urine tests and sometimes ultrasound and biopsy. A comprehensive course of treatment may include intravenous fluids to correct dehydration, vitamin injections, and medications. Some cats may require surgery to remove blockages in their kidneys. Dietary changes can also support treatments. For example, a kidney-friendly diet may contain omega-3 fatty acids and vitamin D.

Thankfully, the majority of diabetes in cats can be cured. Depending on the severity of the condition, it can even lead to a period of remission. The estimated remission rate can vary from 17 percent to 60%.


A cat in a coma is a sign that diabetes has progressed to a critical stage. A cat in this condition is unable to utilize blood glucose for energy and starts using fat and muscle stores for energy. This can lead to lethargy and acetone-smelling breath. If left untreated, this condition can lead to ketoacidosis and coma.

This dangerous condition results from a cat’s insulin levels becoming too high or too low. A cat in a diabetic coma is likely to experience some of the symptoms of the disease, including increased thirst and increased urine output. Vomiting, lethargy, and weight loss are also common symptoms of diabetes. Eventually, untreated diabetes can lead to liver disease and other serious illnesses. In severe cases, the cat can fall into a coma and die.

The first step is to perform a blood glucose and urine test. This will be helpful in determining the exact cause of the cat’s diabetes. The goal of diabetes treatment is to keep the blood glucose levels within a normal range. A doctor may also perform other tests to rule out other possible causes of the condition.

Diabetic cats are not discharged from the hospital until their blood glucose levels are stable and they are eating and drinking, as well as urinating on their own. A hospital stay can last anywhere from two to seven days. The treatment aims to correct the high glucose levels and control the other symptoms of the disease. Insulin or dextrose is given in small doses until the blood glucose levels are normal. Occasionally, cats can enter remission and no longer need treatment, but it is vital to diagnose and treat the condition quickly.

The high blood sugar levels can overload the kidneys’ ability to filter glucose from the blood and urine. In addition, the high glucose concentration in the urine pulls excessive water into the urine and results in dehydration. In addition, uncontrolled diabetes can cause nerve damage in the hind limbs. If you notice this in your cat, it is not painful and often resolves on its own once treatment is provided.


Diagnosis of diabetes in cats is similar to that of dogs and can be done with a simple blood test. The veterinarian will look for signs of hyperglycemia (excessive glucose in the blood) and glucose in the urine. Typically, cats’ blood-glucose levels are between 80 and 120 milligrams per deciliter. The presence of ketones in the urine, however, is an indicator of more advanced diabetes.

Diabetic cats may go into remission after treatment. However, the rate of remission depends on the severity of the disease and the management. Although the rates of remission vary, they generally fall in the range of 17 to 60 percent. In older cats, insulin injections may be necessary for the rest of their lives.

Diabetes in cats is caused by insulin resistance in the body’s tissues. In cats with type II diabetes, insulin-producing cells fail to produce enough insulin to properly feed the body. Because insulin is secreted late, the cat’s tissues don’t respond to the insulin produced. Other factors, such as obesity, may also contribute to the condition.

Diabetes in cats may not be immediately apparent, so it is important to seek medical treatment as soon as possible. The symptoms of the disease may be similar to those of other conditions, including urinary tract infections or hyperthyroidism. A cat with diabetes may be “off” during the early stages, and may suddenly have accidents or lose weight.

When untreated, diabetes in cats can lead to ketoacidosis, a potentially life-threatening condition. Ketones, byproducts of fat metabolism, are toxic to tissues and organs. Symptoms of this condition include lethargy, vomiting, abdominal pain, and even coma. Diabetic cats may also require emergency medical attention, which may include fluid therapy and insulin therapy.
