Kidney Disease in Cats

Understanding Kidney Disease in Cats

What every cat parent should know

Kidney disease is one of the most common health problems in older cats, but it can affect younger cats too. At Pusat Veterinar Healing Pets, we’re here to help you spot the signs early and manage your cat’s health with compassion and care.

What Do the Kidneys Do?

The kidneys have a big job! They:

• Filter waste and toxins from the blood

• Balance water and electrolytes

• Help control blood pressure

• Support red blood cell production

When the kidneys aren’t working properly, waste builds up in the body and can make your cat very sick.

What Is Kidney Disease?

Kidney disease (or kidney failure) happens when the kidneys slowly lose their ability to function over time. This condition is also called chronic kidney disease (CKD), and it tends to get worse gradually.

It’s more common in senior cats (over age 7), but it can happen at any age due to genetics, infections, toxins, or other illnesses.

Signs of Kidney Disease in Cats

You might notice subtle changes at first. Common symptoms include:

• Drinking more water than usual

• Peeing more often or in larger amounts

• Weight loss

• Loss of appetite

• Vomiting or nausea

• Bad breath (sometimes with a chemical or “urine-like” smell)

• Lethargy or weakness

• Poor coat condition

If you notice any of these signs, it’s important to schedule a vet visit. Early diagnosis can make a big difference!

How Is It Diagnosed?

We use a combination of:

• Blood tests – to check for waste buildup (like creatinine and BUN)

• Urine tests – to see how well the kidneys are concentrating urine

• Blood pressure – high blood pressure is common with kidney problems

• Sometimes ultrasound or x-rays – to look at the kidney structure

Can It Be Treated?

There’s no cure for chronic kidney disease, but it can be managed – and many cats live happily for months or even years after diagnosis.

Treatment may include:

• Prescription kidney diet – low in phosphorus and protein to reduce kidney workload

• Fluids (subcutaneous or IV) – to prevent dehydration

• Medications – to control nausea, blood pressure, or protect the kidneys

• Supplements – for potassium, vitamins, or appetite support

• Regular monitoring – blood and urine tests to track kidney health over time
