What chronic kidney disease is
Chronic kidney disease, or CKD, is one of the most common conditions seen in older cats. It develops when the kidneys slowly lose their ability to filter waste from the blood, usually over months or years. Because the change is gradual, cats often cope well in the early stages and may seem quite normal for a long time. This slow start is part of why the disease can be present before anyone notices. Understanding what it is helps you know what signs to look for and why check-ups matter.
Early signs are easy to miss
The first signs of CKD are often subtle and easy to put down to ageing. You might notice your cat drinking and urinating more than before, or losing weight gradually over time. A poorer appetite, lower energy and a duller, less well-kept coat can also creep in slowly. Because these changes are so gentle, they are easy to overlook until the disease is more advanced. If you notice any of them, it is well worth mentioning to your vet, as catching them early can make a real difference.
Managing it well
Chronic kidney disease cannot be cured, but it can very often be managed for a long and comfortable time. Early detection through blood and urine tests, including a marker called SDMA, allows your vet to start support sooner. A kidney-friendly diet and good hydration help ease the load on the kidneys and keep your cat feeling well. Your vet may also advise controlling phosphate levels and blood pressure as part of the plan. With the right care, many cats live happily for years after diagnosis.
Why senior check-ups matter
Because CKD can be present long before obvious signs appear, regular check-ups and screening for senior cats are especially valuable. Routine blood and urine tests can pick up early changes while your cat still feels well, giving you the best chance to act. Catching the disease early genuinely changes the outlook and the choices available to you and your vet. Many vets recommend more frequent check-ups as cats reach their senior years. Working together with your vet, you can give your older cat the comfortable, well-supported life they deserve.
