Chronic kidney disease (CKD) is defined as any abnormality of one or both kidneys that has been present for several months. It is a common condition, affecting about 1 of every 3 cats.1
Your cat’s kidneys play a vital role in removing metabolic wastes from the bloodstream, regulating fluid and electrolyte balance, producing or activating important hormones and helping control blood pressure. If your cat’s kidneys cannot do their job properly, CKD can eventually lead to life-threatening problems.
The cause of CKD in cats often is unknown; however, several factors
may be involved that could increase your cat’s risk of developing
kidney disease:
Catching CKD before signs become obvious is important since signs do not typically appear until 75% of kidney function has been lost. At 7 years and older, a cat’s kidney disease risk increases, so be sure to get a “senior screening” during their annual check-up. CKD is progressive and irreversible, but your veterinarian can help provide long-term care and show you how to track signs in older cats.
The signs of early-stage kidney disease are not visible. On diagnosis, CKD has already been present for some time but may be managed with the help of vet-recommended cat food for kidney disease. Signs of late-stage kidney disease tend to be similar but are far more noticeable to pet parents.
