Kidney Disease In Cats: Symptoms And Treatments

Kidney Disease In Cats

What Is Kidney Disease In Cats?

Kidney disease is a common health issue that affects cats of all ages. The kidneys play a vital role in filtering waste products and maintaining the balance of fluids and electrolytes in a cat's body.

When the kidneys are not functioning properly, it can lead to a range of health problems and potentially life-threatening conditions.

There are two primary types of kidney disease in cats: Acute kidney disease and chronic kidney disease. Acute kidney disease occurs suddenly and is often the result of a specific event, such as ingestion of toxins, urinary obstruction, or a severe infection.

Chronic kidney disease, on the other hand, develops gradually over time and is typically caused by factors such as aging, genetic predisposition, or underlying health conditions.

Clinical Signs Of Kidney Disease In Cats

The symptoms of kidney disease in cats can vary depending on the stage and severity of the condition.

Some common symptoms include:

  • Increased thirst (polydipsia)
  • Increased urination (polyuria)
  • Weight loss
  • Decreased appetite (anorexia)
  • Vomiting
  • Diarrhea
  • Lethargy
  • Dehydration
  • Bad breath
  • Mouth Ulcers
  • Pale gums
  • High blood pressure
  • Changes in behavior
  • Litter box habits
  • Fever
  • Inactive
  • Urinating Or Defecating In The House
  • Difficulty Urinating
  • Edema

As the disease progresses, cats may also exhibit signs of weakness, poor coat quality, and muscle wasting.

Treatment Options For Kidney Disease In Cats

The treatment approach for kidney disease in cats aims to manage symptoms, slow down the progression of the disease, and support kidney function.

Treatment options may include dietary modifications, specifically tailored to meet the nutritional needs of cats with kidney disease.

These diets are typically low in phosphorus and high-quality protein. Fluid therapy may be recommended to maintain hydration and flush out toxins.

Medications may be prescribed to control blood pressure, manage symptoms like nausea or vomiting, and address underlying conditions.

Regular monitoring of kidney function through blood tests and urinalysis is crucial to assess the effectiveness of the treatment plan.

Home Remedies For Kidney Disease In Cats

It's important to note that kidney disease in cats requires veterinary care and professional management.

However, there are some supportive measures and home remedies that can complement the prescribed treatment plan.

These include:

  • Hydration: Ensure your cat has access to clean and fresh water at all times to maintain proper hydration. If necessary, encourage water intake by providing multiple water bowls or using water fountains.
  • Diet: Work closely with your veterinarian to develop a diet plan that is tailored to your cat's specific needs. A kidney-friendly diet typically includes low phosphorus content and high-quality protein sources. Prescription diets formulated for cats with kidney disease are available and can help support kidney function.
  • Environmental Enrichment: Create a calm and stress-free environment for your cat, as stress can worsen the symptoms of kidney disease. Provide a quiet space for rest, interactive playtime, and mental stimulation to promote overall well-being.
  • Medication Administration: Administer prescribed medications as directed by your veterinarian. This may include medications to manage blood pressure, control nausea or vomiting, or address underlying conditions contributing to kidney disease.
  • Regular Monitoring: Follow the recommended schedule for follow-up veterinary visits and monitoring of kidney function. This allows for adjustments in the treatment plan and early detection of any complications or progression of the disease.

It's important to consult your veterinarian before implementing any home remedies or making significant changes to your cat's diet or treatment plan.

They will provide guidance based on your cat's specific needs and conditions.

How To Prevent Kidney Disease In Cats?

Prevention of kidney disease in cats involves taking proactive measures to maintain their overall health and well-being.

This includes providing a balanced and appropriate diet that promotes kidney health and minimizes the risk of kidney disease.

It's essential to offer fresh, clean water at all times to ensure proper hydration. Regular veterinary check-ups are vital for early detection of any underlying health conditions that may contribute to kidney disease.

Managing underlying conditions such as hypertension or diabetes can also help prevent kidney damage. Avoiding exposure to toxins and medications that are harmful to the kidneys is crucial.

Additionally, maintaining a stress-free environment and providing a litter box that is easily accessible and clean can help prevent urinary tract infections and obstructions that can lead to kidney disease.

Affected Cat Breeds Of Kidney Disease

While kidney disease can occur in cats of any breed, some breeds may have a higher predisposition to certain types of kidney disease.

For example, Persians and Abyssinians are more prone to developing polycystic kidney disease (PKD), a hereditary condition characterized by the formation of fluid-filled cysts in the kidneys.

Maine Coons and Siamese cats may have a higher risk of developing renal amyloidosis, a condition where abnormal proteins accumulate in the kidneys.

Causes For Kidney Disease In Cats


Several factors can contribute to the development of kidney disease in cats.

These include age-related degeneration, genetic predisposition (such as polycystic kidney disease in certain breeds), infections (such as feline infectious peritonitis), immune system disorders, urinary tract obstructions, exposure to toxins or medications, and underlying health conditions like hypertension or diabetes.

Additionally, some cats may be more susceptible to kidney disease due to their genetics or breed predispositions.


Diagnosing kidney disease in cats involves a combination of physical examination, medical history review, blood tests, urinalysis, and imaging techniques like ultrasound.

Blood tests help evaluate kidney function by measuring blood urea nitrogen (BUN) and creatinine levels.

Urinalysis provides information about urine concentration and the presence of protein, blood cells, or bacteria.

In some cases, additional tests like kidney biopsy or imaging may be recommended to assess the extent of kidney damage.

When To See A Vet For Kidney Disease In Cats?

If you suspect your cat may have kidney disease or if you notice any symptoms such as increased thirst, frequent urination, weight loss, poor appetite, or vomiting, it is essential to consult a veterinarian as soon as possible.

Early detection and treatment are crucial in managing kidney disease in cats. Regular veterinary check-ups are also recommended for older cats, as kidney disease is more common in senior felines.

Food Suggestions For Kidney Disease In Cats

When it comes to managing kidney disease in cats, it's important to provide a diet that supports their kidney function and helps minimize further damage.

Here are some general food suggestions for cats with kidney disease:

  • Prescription renal diet: Speak to your veterinarian about prescription renal diets specifically formulated for cats with kidney disease. These diets are designed to be low in protein, phosphorus, and sodium, and often contain increased levels of omega-3 fatty acids.
  • Wet or moist food: Encourage your cat to consume wet or moist food rather than dry kibble. This helps ensure they are getting enough hydration, which is crucial for kidney health.
  • Low-phosphorus diet: Look for cat foods that are labeled as low-phosphorus or are specifically designed for kidney disease. High levels of phosphorus can further strain the kidneys, so it's important to restrict its intake.
  • Limited protein content: While cats require protein, excessive amounts can be taxing on the kidneys. Opt for cat foods that have moderate levels of high-quality protein to meet their needs without overburdening the kidneys.
  • Omega-3 fatty acids: These can help reduce inflammation and support kidney health. Look for foods that are supplemented with omega-3 fatty acids like fish oil or flaxseed oil.
  • Controlled sodium levels: Kidney-diet cat foods typically have reduced sodium content, which helps maintain healthy blood pressure levels. Excess sodium can be detrimental to cats with kidney disease.

Remember to consult your veterinarian before making any significant changes to your cat's diet.

They can provide tailored recommendations based on your cat's specific needs and stage of kidney disease. Regular veterinary check-ups and monitoring are essential to ensure your cat's kidney disease is managed effectively.


Kidney disease is a significant health concern in cats, and early detection and appropriate management are crucial for the well-being of our feline companions.

Understanding the symptoms, causes, treatment options, and preventive measures can help cat owners make informed decisions and provide the best possible care.

Regular veterinary check-ups, a balanced and kidney-friendly diet, and a stress-free environment are key components of managing kidney disease.

By working closely with your veterinarian and providing the necessary support, you can help improve the quality of life for your cat and manage their kidney disease effectively.
