As much as we wish our furry companions could stay forever young, the reality is that our cats, like us, age and face health challenges over time. If you’ve found yourself reading this article, it’s likely because your older cat has been diagnosed with kidney disease, and you’re looking for ways to ease their journey.
Kidney disease in cats is common, especially in senior cats, and it can feel overwhelming to watch your beloved feline friend go through changes in their health. But don’t worry—while there is no cure, how to help older cats with kidney disease can make a significant difference in their quality of life. By staying informed, adjusting their lifestyle, and working closely with your vet, you can help your cat live a comfortable and fulfilling life, even with kidney disease.
Let’s dive into the essential steps you can take to support your older cat in their battle with kidney disease.

Understanding Kidney Disease in Older Cats
Before we discuss how to help your senior cat with kidney disease, it’s crucial to understand what kidney disease is and why it’s common in older cats.
What is Kidney Disease in Cats?
Kidney disease in cats is a condition where the kidneys lose their ability to filter waste and maintain fluid balance. Over time, this leads to an accumulation of toxins in the body, which can cause symptoms like excessive thirst, urination, lethargy, and weight loss.
The kidneys also help regulate other important functions, such as red blood cell production and blood pressure. When kidney function declines, it can lead to complications like anemia, high blood pressure, and electrolyte imbalances.
Why is Kidney Disease Common in Older Cats?
As cats age, their organs naturally begin to wear down, and the kidneys are no exception. While the exact cause of kidney disease in cats is not fully understood, age is a significant factor. Other contributing factors include:
- Chronic dehydration: Older cats are less likely to drink enough water, leading to chronic dehydration, which can damage the kidneys.
- Genetics: Some breeds, like Persians and Abyssinians, are more prone to kidney disease.
- High blood pressure and diabetes: Conditions that can further exacerbate kidney issues in senior cats.
How to Spot Kidney Disease in Older Cats
If you suspect your older cat might have kidney disease, early detection is key. Here are some of the common signs of kidney disease in cats:
- Increased thirst and urination: Your cat may drink more water than usual and urinate more frequently. This is because the kidneys can no longer concentrate urine effectively.
- Weight loss: Despite having a normal or increased appetite, your cat may lose weight due to poor nutrient absorption.
- Lethargy: Kidney disease can cause your cat to feel weak and lethargic, leading to reduced activity levels.
- Vomiting and nausea: The buildup of toxins in the body can cause nausea, leading to vomiting or a decreased appetite.
- Poor coat quality: A cat’s coat may become dull and unkempt as the disease progresses.
If you notice any of these signs, it’s essential to consult your vet immediately for a diagnosis. Blood tests, urinalysis, and ultrasounds are common methods used to assess kidney function in cats.

How to Help Older Cats with Kidney Disease: Key Strategies
Now that you understand the basics, let’s explore how you can actively help your older cat manage kidney disease and lead a comfortable life.
1. Ensure Proper Nutrition with a Kidney-Friendly Diet
Diet is one of the most important aspects of managing kidney disease in cats. A special kidney-friendly diet can help slow the progression of the disease and improve your cat’s quality of life.
- Low Protein: High-protein diets can put extra strain on the kidneys. Look for food that’s specifically formulated for kidney health, which tends to be lower in protein but still meets your cat’s nutritional needs.
- Phosphorus Control: Foods with reduced phosphorus can help prevent further kidney damage. High phosphorus levels can worsen kidney disease.
- Increased Moisture: Cats with kidney disease are often dehydrated. Feeding wet food or adding water or broth to your cat’s meals can help increase their fluid intake.
Tip: Consult with your vet to determine the best diet for your cat. If your cat is a picky eater, they may need some coaxing to get used to the new food.
2. Encourage Hydration (and How to Do It)
One of the biggest challenges with kidney disease is dehydration. Dehydration further damages the kidneys, so it’s important to encourage your cat to drink more water.
- Provide Fresh Water: Make sure your cat always has access to fresh water. Some cats are more likely to drink from a cat water fountain as they prefer moving water.
- Wet Food: As mentioned earlier, wet food is an excellent way to boost hydration. You can also mix water or broth into your cat’s food to make it more appealing.
- Subcutaneous Fluids: In more advanced cases of kidney disease, your vet may recommend giving your cat subcutaneous fluids at home. This involves injecting a saline solution under your cat’s skin to hydrate them. It may sound intimidating at first, but many pet owners quickly learn to do this at home with guidance from their vet.
3. Manage Other Health Conditions
Kidney disease often doesn’t exist in isolation. Older cats may also have other conditions, like high blood pressure or diabetes, which can worsen kidney disease.
- High Blood Pressure: Cats with kidney disease are more likely to develop high blood pressure, which can further damage the kidneys. Your vet may prescribe medication to help control your cat’s blood pressure.
- Diabetes Management: If your cat has diabetes, managing blood sugar levels is crucial. High blood sugar can put additional stress on the kidneys, so maintaining a balanced diet and administering insulin (if needed) is important.
Working with your vet to address these underlying issues will provide better support for your cat’s kidney health.
4. Monitor and Support Your Cat’s Comfort
Kidney disease can cause discomfort, so it’s essential to monitor your cat’s overall well-being.
- Pain Management: Some cats may experience pain from kidney disease, particularly if they have other complications like kidney stones. Your vet may recommend pain relief medications or supplements to help manage this discomfort.
- Monitor Weight: Loss of muscle mass is common in senior cats with kidney disease. Keep track of your cat’s weight and talk to your vet about appropriate steps to maintain their body condition.
5. Regular Vet Checkups
Managing kidney disease in older cats is a long-term commitment. Regular vet visits are necessary to monitor kidney function and make adjustments to treatment plans as needed.
- Blood Tests: Blood tests are used to monitor kidney function, check electrolyte levels, and assess the effectiveness of the treatment.
- Urine Tests: Your vet may also perform urine tests to check for protein levels and how well the kidneys are concentrating urine.
Be sure to follow your vet’s recommendations and schedule regular checkups to ensure your cat’s health stays on track.
Frequently Asked Questions (FAQs)
1. Can kidney disease in cats be cured?
Unfortunately, kidney disease in cats is not curable, but it can be managed with proper care and treatment. Early intervention can make a significant difference in your cat’s quality of life.
2. How long can a cat live with kidney disease?
The lifespan of a cat with kidney disease varies, depending on the stage of the disease and how well it is managed. With the right treatment, many cats live for several years after diagnosis.
3. My cat is very picky about food. What can I do?
If your cat is refusing kidney-friendly food, try offering a variety of wet foods or adding toppings like tuna juice or chicken broth to encourage them to eat. Always check with your vet if you need alternatives.
