Chronic kidney disease affects roughly 30% of cats over 15. Early stages are often silent — by the time symptoms appear, the disease may already be advanced. Catching small daily changes is everything.
When kidney function declines, the body can no longer retain fluids efficiently, leading to increased thirst and urination.
Large volumes of dilute urine are a classic early sign of CKD. Pay attention to how often your cat visits the litter box.
If your cat is losing weight despite a normal appetite, kidney trouble may be the hidden cause.
Toxin buildup in the bloodstream causes fatigue and general weakness — easy to dismiss as normal aging.
Nausea from uremia. If your cat is vomiting on an empty stomach or more frequently than before, take note.
An ammonia-like odor from the mouth is a sign that the kidneys are struggling to filter waste products from the blood.
Chronic kidney disease (CKD) is one of the top three causes of death in cats. The kidneys gradually lose their ability to filter waste from the blood, leading to a slow buildup of toxins throughout the body.
CKD is most common in senior cats aged 7 and older, with roughly 30% of cats over 15 affected. Because early-stage CKD often produces no obvious symptoms, it's sometimes called a 'silent killer.'
Kidney tissue cannot regenerate once lost, which is why early detection and management are so critical — they can significantly extend your cat's life expectancy and quality of life.
Blood tests may appear normal. Urine concentration ability is mildly reduced. Detection at this stage gives the best outcomes.
Increased drinking and urination begin. Subtle changes in weight and appetite. Mild abnormalities on bloodwork.
Clear symptoms emerge — vomiting, dehydration, anemia. Active treatment and dietary management are essential.
Uremic symptoms dominate. Maintaining quality of life becomes the primary goal through IV fluids and medications.
CatsMe's AI health check analyzes photos of your cat to detect subtle changes in condition — weight shifts, posture, coat quality. If you suspect kidney issues, use CatsMe to track daily changes and build a record to share with your vet.
Get Started FreeChronic kidney disease cannot be cured, but with early detection and proper management, its progression can be significantly slowed. A combination of dietary therapy, fluid support, and medication can help maintain your cat's quality of life for years.
A blood panel (BUN, creatinine, SDMA) plus urinalysis typically costs $80–$250 depending on your vet. Regular screening is the most cost-effective way to catch CKD early before it progresses.
A prescription kidney diet with restricted phosphorus, sodium, and moderate protein is recommended. Work with your vet to find a food your cat will actually eat — compliance matters more than perfection.
