A uncommon condition called diabetes insipidus can afflict both people and animals, including cats. In this article, we discuss how your cat can scale through this condition if gotten.

Diabetes insipidus is a rare disorder that affects both humans and animals, including cats. Unlike diabetes mellitus, which is a more common form of diabetes in cats, diabetes insipidus is not related to glucose regulation or insulin production. 

Instead, it is caused by a deficiency or insensitivity to antidiuretic hormone (ADH), which helps regulate water balance in the body. This condition can lead to excessive thirst, urination, and dehydration, and can be challenging to diagnose and manage in cats. 

In this article, we will explore the causes, symptoms, diagnosis, and treatment options for diabetes insipidus in cats, as well as some helpful tips for caring for a cat with this condition.

Diabetes Mellitus vs Insipidus in cats

Diabetes insipidus vs Mellitus is a common comparison when it comes to diabetes in people and also in cats.

Diabetes mellitus is a disease that occurs when the body does not make enough insulin or does not use the insulin that it does produce properly. On the flip side, diabetes insipidus is an uncommon disorder that manifests as excessive urine and thirst when the body is unable to control the balance of water in the body.

However, as the conditions are different, so are their causes, symptoms and treatments.


Diabetes insipidus in cats is caused by a deficiency or insensitivity to antidiuretic hormone (ADH), also known as vasopressin. ADH is produced in the hypothalamus of the brain and is stored by the posterior pituitary gland. When ADH is produced, it influences the kidneys to control how much water is expelled in urine. In cats with diabetes insipidus, either the production or function of ADH is impaired, resulting in an inability to concentrate urine and retain water in the body. This can be caused by a variety of factors, including genetic mutations, head trauma, tumors, infections, and autoimmune diseases. Sometimes the reason may be idiopathic, which simply means that it is unidentified.

Symptoms of Diabetes Insipidus

The main clinical signs of diabetes insipidus in cats include increased thirst, urination, and dehydration. The following are the most typical warning signs:

  • Increased water consumption: Diabetes insipidus cats will drink an excessive amount of water to make up for the significant water loss through urination.

  • Diabetic cat peeing everywhere: A diabetic cat urinating a lot (dilute urine) is a sign of water diabetes in a cat. This can lead to accidents outside the litter box, and sometimes inappropriate urination.

  • Dehydration: Cats with diabetes insipidus may get dehydrated despite consuming a lot of water because their bodies are unable to retain adequate water. Numerous symptoms, including tiredness, dry mouth, sunken eyes, and a lack of skin suppleness, may result from this.

  • Weight loss: Some diabetes insipidus cats may experience weight loss, as their bodies try to compensate for the increased water loss by breaking down fat stores for energy.


As a result of its symptoms being similar to those of other urologic disorders, diabetes insipidus in cats can be challenging to diagnose. The initial steps a veterinarian often takes are a thorough medical history and physical examination. They may also carry out various diagnostic procedures, such as:

  • Urinalysis: A urinalysis can be performed to determine the concentration of the cat's urine and identify any irregularities.

  • Water deprivation test: In this test, water is withheld from the cat for a predetermined amount of time, and the cat's urine production and concentration are monitored.

  • Blood testing: With the use of blood tests, it is possible to assess kidney function and rule out any underlying medical disorders.

  • MRI or CT scan: Imaging tests can help identify any abnormalities in the brain or pituitary gland that may be causing the diabetes insipidus.


A synthetic antidiuretic hormone (ADH) named DESMOPRESSIN is frequently used to treat diabetic insipidus in cats. This drug is used to replenish the body's deficient ADH hormone and is offered as a nasal spray, pill, or injection. DESMOPRESSIN helps the kidneys to reabsorb more water, which reduces urine output and improves hydration levels in the body.

In addition to medication, it's also important to monitor and manage the cat's water intake and provide access to fresh water at all times. You may also need to monitor their urine output and fluid intake closely, as well as adjust their diet to support their kidney function.

Diabetes Insipidus Life Expectancy for Cats

Like with people, the underlying cause, the severity of the ailment, and the efficacy of the therapy all affect how long a cat with diabetes insipidus will live.

The prognosis may be bad if a tumor or another major medical disease is the underlying cause of diabetes insipidus in cats. However, the cat may have a normal life expectancy if the disease is brought on by a medicine or a head injury and is treated swiftly and effectively.


How To Prevent Diabetes Insipidus In Cats

Since diabetes insipidus in cats can be brought on by a number of things, including heredity and underlying medical disorders, there is no certain method to prevent it. To reduce the possibility that your cat may have this ailment, you can take the following steps:

  • Regular veterinary check-ups: Regular check-ups with a veterinarian can help identify any underlying health issues that may lead to the development of diabetes insipidus. This can also help with early diagnosis and treatment of the condition.

  • Provide clean water: Providing your cat with clean, fresh water at all times can help ensure that they are properly hydrated and may reduce the risk of dehydration.

  • Avoid head trauma: Diabetes insipidus in cats is frequently brought on by head trauma, so it's crucial to keep your cat secure and steer clear of situations that might cause head trauma.

  • Keep an eye on your cat's behavior: Consider seeking veterinarian treatment if you detect any troubling signs and keep an eye out for any adjustments in your cat's behavior or health, such as increased thirst or urine.

  • Maintain a healthy weight: Obesity can increase the risk of developing a range of health conditions, including diabetes insipidus. Ensuring that your cat maintains a healthy weight can help reduce the risk of developing this condition.

While there is no way to completely prevent diabetes insipidus in cats, taking these steps can help reduce the risk of developing this condition and ensure that your cat stays healthy and happy.
