What is Chronic Kidney Disease (CKD)?

​

Chronic Kidney Disease (CKD) is a progressive condition where your cat’s kidneys gradually lose their ability to function properly. The kidneys are responsible for filtering waste products from the blood, regulating fluid balance, and maintaining electrolyte levels. Over time, as kidney function declines, waste builds up in the bloodstream, which can cause a variety of symptoms.

CKD is commonly diagnosed in older cats, and its progression can be classified into stages using the International Renal Interest Society (IRIS) system. These stages are based on the level of kidney function and the degree of kidney damage:

​

• Stage 1: Early kidney disease, with mild changes in kidney function. Often no clinical signs are present.

• Stage 2: Moderate kidney dysfunction, with mild to moderate clinical signs.

• Stage 3: Severe kidney dysfunction, with significant clinical signs.

• Stage 4: End-stage kidney failure, with very severe clinical signs.

The disease progresses slowly, but early diagnosis and management can help extend your cat’s quality of life.

Managing Chronic Kidney Disease

​

Although CKD cannot be cured, there are several ways to manage the disease and improve your cat’s quality of life:

 

Dietary Management:

Renal-specific diets are crucial for supporting kidney function and slowing disease progression. These diets are designed to reduce the workload on the kidneys and help manage symptoms. We recommend the following diets, ideally wet food due to increased water content, but you can feed dry if necessary:

​

• Royal Canin Renal 

• Hill’s k/d 

We recommend transitioning your cat onto these diets over a 1-2 week period. If your cat refuses to eat renal food after a gradual transition, we recommend trying a Royal Canin or Hill’s senior cat diet as an alternative, with an added phosphate binder which we can supply.

 

Hydration:

Cats with CKD may be prone to dehydration, so it's essential to ensure they are drinking enough water. Consider offering wet food to increase fluid intake, and providing fresh water in a few different locations in the house at all times; water fountains can be an excellent option to increase water intake. In some cases, your vet may recommend subcutaneous fluid therapy to help maintain hydration.

 

Medications: 

​

Depending on the stage of the disease, your vet may prescribe medications to help manage symptoms, such as:

​

• Phosphate binders to reduce the levels of phosphate in the blood

​

• Anti-hypertensives if your cat has high blood pressure

​

• Potassium supplements if potassium levels are low

​

​

Managing Symptoms: 

​

As CKD progresses into later stages, you may notice that your cat has good and bad days. To manage these symptoms, additional treatments might be necessary, including:

​

• Pain relief

​

• Anti-emetics to control vomiting

​

• Appetite stimulants to encourage eating

 

If you notice your cat is having more bad days than good, please schedule a check-up with us. A tailored treatment plan can be created to support your cat’s needs.

​

​

Check-Ups and Monitoring

​

Regular check-ups and monitoring are crucial in managing CKD. We recommend:

​

• Blood tests, Blood Pressure Measurements and Urine screening every 3-6 months to assess kidney function and detect any changes early.

​

• Regular weight checks to monitor your cat's overall health and nutritional status.

The frequency of check-ups may increase as the disease progresses, and additional tests may be needed to evaluate your cat’s kidney function and any other related conditions.

​

​

Prognosis and Life Expectancy

​

The prognosis for cats with CKD depends on the stage at which the disease is diagnosed and how well it is managed.

​

• Stage 1: With early intervention, cats can live for several years with a good quality of life.

• Stage 2: Cats may live for 1-3 years with proper management.

• Stage 3: Cats in this stage can live for several months to a year, or longer, depending on treatment and response.

• Stage 4: The prognosis in end-stage kidney failure is more guarded, and without intensive care, life expectancy may be limited to weeks or months.

Regular veterinary care, appropriate diet, and medications can help improve your cat's prognosis and extend their life.

Other Common Conditions Seen in Cats with CKD

​

Cats with CKD may also develop other health problems, including:

​

• High blood pressure (Hypertension): A common complication of CKD that may need to be managed with medication.

​

• Anaemia: CKD can cause a decrease in red blood cell production, leading to anaemia. This may be managed with medication or supplements.

​

• Urinary tract infections (UTIs): Cats with CKD are at higher risk of UTIs, which may need to be treated with antibiotics.

​

• Dehydration: Cats with CKD often struggle to maintain proper hydration, which can exacerbate the disease.

Regular monitoring helps catch these conditions early, allowing for appropriate treatment.
