The Connection Between Kidney Disease and Diet in Cats

Cats, like humans, can develop kidney disease. It is a common problem among cats, especially as they age. While there are various causes of kidney disease, diet is a significant factor. A cat's diet can affect both the development and the progression of kidney disease.

The Connection Between Kidney Disease and Diet in Cats

The Role of Diet in Kidney Disease

Kidneys play a crucial role in a cat's body. They help remove waste products and excess fluids from the body, regulate electrolyte balance, and produce hormones that regulate blood pressure and red blood cell production. If a cat's kidneys are damaged, they cannot perform these functions correctly. Kidney disease can be caused by various factors, including infections, toxins, and genetics. However, diet is among the most significant factors that can affect kidney health in cats.

According to experts, a cat's diet should provide a proper balance of water, protein, fat, and minerals to maintain the kidneys' health. A specific type of protein called high-quality protein is essential in a cat's diet because it provides the necessary amino acids that the body needs to build and repair tissues. However, when a cat's diet is high in low-quality protein, the kidneys must work harder to eliminate the waste products. Over time, this can damage the kidneys and lead to kidney disease.

What to Feed a Cat with Kidney Disease

If your cat has kidney disease, a proper diet can help manage the condition and slow down its progression. Your vet may recommend a special kidney diet that is low in phosphorus and protein but high in water and fiber. These diets are designed to reduce the workload on the kidneys and help maintain their function. They also help prevent complications such as high blood pressure and urinary tract infections.

It is crucial to note that cats with kidney disease have different nutritional requirements than healthy cats. Therefore, it is essential to follow your vet's recommended diet for your cat's specific condition. Additionally, you should never make any significant changes to your cat's diet without consulting your vet first.


Kidney disease is a common problem among cats, and diet plays a significant role in its development and progression. A proper diet can help maintain a cat's kidney function and slow down the disease's progression. However, it is essential to follow your vet's recommendations for your cat's specific condition. With proper care and attention, you can help your cat live a long, healthy life, even with kidney disease.
