In short: chronic kidney disease (CKD) is one of the most common conditions in older cats. The earliest sign is usually drinking and urinating more, followed by weight loss, reduced appetite, a dull coat, and bad breath. CKD cannot be cured, but with early diagnosis and the right care many cats live comfortably for years. Care focuses on maintaining hydration, managing blood pressure, and supporting appetite. If your cat shows these signs, message Dr. Prabasa on WhatsApp for an initial assessment.
Hearing the words "kidney failure" is frightening, but in cats CKD is a condition you can support. Unlike sudden acute kidney failure, CKD develops slowly over months to years. Precisely because it is slow, early detection is so valuable.
What CKD is and why it is common in older cats
The kidneys filter waste from the blood, regulate fluids, and keep minerals in balance. In CKD, kidney tissue is gradually damaged and cannot recover. Cats hide illness well, so signs often only appear once much of kidney function has already declined.
CKD is very common in elderly cats. That is why routine blood and urine testing in senior cats is so important, it can catch CKD earlier than waiting for obvious signs.
Signs of CKD in cats
Signs develop gradually. The earliest and most important:
- Drinking more and urinating more (larger or more frequent litter clumps). Often the first visible sign.
- Gradual weight loss even while still eating.
- Reduced appetite, becoming fussy, or eating less.
- A dull, unkempt coat, because the cat grooms less.
- Lethargy and more sleeping.
- A distinctive bad breath (sometimes ammonia-like), with nausea and occasional vomiting.
- In advanced stages: dehydration, constipation, and a more obvious decline.
Many owners view drinking and urinating more as "an old thirsty cat," yet this is one of the most important signals to have the kidneys checked.
How a vet assesses CKD
Diagnosis and staging use a combination of:
- Blood tests to assess kidney-function markers and mineral balance.
- Urine testing, including urine concentration and the presence of protein, which often gives an earlier clue than blood.
- Blood pressure measurement, since hypertension often accompanies CKD and can damage the eyes, brain, and heart if left unmanaged.
The International Renal Interest Society (IRIS) uses a CKD staging system to guide treatment. Determining the stage helps the vet build a suitable plan and monitor progression.
Cats with CKD are often very stressed at a clinic, and that stress can distort results, for example falsely raising blood pressure. Collecting blood and urine and measuring blood pressure at home is often more comfortable and accurate. Dr. Prabasa can come for these assessments in the place your cat knows, then refer to a clinic if imaging such as a kidney ultrasound is needed.
Care and what you can do at home
CKD cannot be cured, but much can be done to slow it and keep a cat comfortable:
- Maintain hydration. Offer fresh water in several spots, consider a cat fountain, and increase wet food. Cats with CKD dehydrate easily.
- Renal diet. A prescription kidney diet (with adjusted phosphorus and protein) is proven to help quality and length of life in CKD cats. The transition should be gradual and guided by the vet, do not force it to the point the cat stops eating.
- Fluid support. For advanced cats, vets sometimes teach giving fluids under the skin (subcutaneous) at home. This is only done after being trained and on the vet's guidance.
- Manage blood pressure and nausea as prescribed, when needed.
- Monitor appetite and weight regularly and record changes.
- Reduce stress. A calm environment helps a CKD cat feel more comfortable and willing to eat.
Important: do not give human medicines to cats without a vet's guidance. Many human pain and anti-inflammatory drugs are very dangerous to a cat's kidneys, and paracetamol can be fatal to cats even at a small dose. For a CKD cat with already weakened kidneys, drug choices must be very careful and always through a vet.
When to see a vet right away
CKD can suddenly worsen (a uremic crisis). Seek help right away, including a 24-hour clinic outside normal hours, if your cat:
- Stops eating for more than a day.
- Vomits repeatedly or seems very weak.
- Is not urinating, or urinating very little.
- Breathes fast, has seizures, or seems confused.
- Is clearly dehydrated (dry gums, sunken eyes).
A cat that will not eat is more urgent than a dog, because a few days without food can trigger a serious liver problem.
Closing
CKD is a lifelong condition, but with the right monitoring and care many senior cats still enjoy long, comfortable days with you. What matters most is early detection and consistent care. If you notice your cat drinking and urinating more or starting to lose weight, do not wait, message Dr. Prabasa on WhatsApp for an assessment. Dr. Prabasa can come to your home across Greater Jakarta for calm sampling and evaluation, and will honestly refer to a clinic if more complete testing is needed.
