What is kidney disease in cats?

 

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.

What causes kidney disease in cats?

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:

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.

Nutrition for cats with kidney disease

If your cat has kidney disease, the nutrition formulated for them can help make an impact on their lives. Specially formulated therapeutic foods that contain decreased amounts of phosphorus and highly digestible protein, and increased omega-3 fatty acids from fish oil have been shown to support quality and length of life in cats with CKD compared to feeding a non-therapeutic food.

 

Your cat’s appetite may vary over time when they have CKD and offering different forms (dry, stews) and flavors of an appropriate food recommended by your veterinary healthcare team can be very helpful. The single most important thing you can do is make any changes to a new food gradually because some cats need several weeks or longer to get used to a new food.

What about using a homemade diet for cats with kidney disease?

 

While it has gained some popularity online, using a homemade food (or a raw food) for cats with kidney disease requires you to take into account several factors, including contamination risks, balancing nutrients, and the overall cost. When looking into nutritional options for cats with kidney disease, it’s always best to get a specific recommendation from your veterinarian.
