Kidney disease is one of the most common conditions in senior cats. Spotting it early can add comfortable years to their life.
Why kidneys matter
The kidneys filter waste, balance fluids, and support many body functions. Chronic kidney disease is extremely common in older cats, developing slowly as kidney function declines. Because cats compensate so well, signs often appear only once a good deal of function is already lost — making early screening valuable.

Early signs to watch
The most common early clues are increased thirst and urination, along with gradual weight loss. You may refill the water bowl more often and scoop larger or more frequent clumps from the litter box. These subtle changes are easy to miss, so it helps to know what to look for.
Later signs
As the disease advances, cats may show reduced appetite, vomiting, bad breath with an ammonia-like odor, a poor or unkempt coat, lethargy, and constipation from dehydration. Any of these, especially in an older cat, is a reason to see the vet.
Hydration and diet
Because failing kidneys struggle to conserve water, keeping a cat well hydrated is central to care. Many cats drink more from a moving source, so a pet water fountain and plenty of fresh bowls can help. Your vet may also recommend a therapeutic kidney diet to reduce the workload on the kidneys.
Early testing pays off
Routine bloodwork and urine tests, especially in cats over seven, can catch kidney disease before symptoms are obvious. While the damage cannot be reversed, early management with diet, hydration, and medication can slow progression and keep your cat comfortable for years.
