Best Cat Food For Kidney DiseaseWhile kidney problems may seem like a debilitating condition for cats, they can often be managed through prescription diets. Using a therapeutic kidney diet is the most important thing you can do to limit the progression of kidney disease. But because there are so many options available in the market, looking for the best diet for your cat can be overwhelming.

Be sure to work with your vet to get the right food for your feline friend, and read below to find out more about the 8 best cat food for kidney disease.  

What is Feline Kidney Disease?

Before we jump straight to the best cat food that can help support your cat’s kidney function, let’s first discuss what this disease means for cats. Just like in humans, healthy kidneys play a vital role in cats, and are responsible for a wide range of bodily functions, including the following:

  • Controlling their blood pressure
  • Limits production of parathyroid hormone 
  • Pushes the generation of red blood cells
  • Filters waste from their blood
  • Allows the production of urine
  • Helps to prevent dehydration
  • Regulates the production of minerals such as sodium and potassium

Unfortunately, cats are like humans and the function of their kidneys will deteriorate over time, making it a common disease in older cats. Thankfully, this condition can be corrected if you spot early symptoms in your pet and take the proper course of action as suggested by your vet. When left untreated, this condition may result in various health issues such as vomiting, diarrhea, depression, mouth ulcers, and more.    

Signs of Feline Kidney Disease 

Because kidney disease can take a while to develop, the initial signs will be subtle; over time, they can play havoc in your cat’s kidneys. Below are 7 signs of this condition in cats. 

  • Urinating a lot more than usual
  • Increased thirst 
  • Reduced appetite, leading to a dehydrated coat
  • Weight loss
  • Constipation
  • Anemia
  • Lethargy 

Unfortunately, most cat owners will ignore the symptoms that their feline exhibits, such as constipation or sudden weight loss. They will often think that their pet simply has a sensitive stomach, ruling out the possibility of kidney failure. In many cases, ⅔ of diagnosed cats will already have dysfunctional kidneys before they even display any of the clinical signs above.

Things to Consider in Cat Food for Kidney Disease

Because there’s currently no way to cure kidney disease, medical treatment, and a specialized diet are the only options to help your cat manage this condition. This can be achieved by feeding our pets food that’s low in protein, sodium, and phosphorus since kidney disease leads to their limited disposal. With this knowledge, be sure to check for the following when looking for the best cat food.  


Be sure to check for foods that are low in protein, since breaking this down can create excess waste products which will push the kidneys to work even harder. While protein does play a crucial role in your cat’s health, they will be able to function better with foods that contain high-quality proteins in low concentrations. Keep in mind that because you’re providing a lower amount of proteins, it’s important to give your cat the best sources of protein possible.  

Low Sodium

Another process that the kidneys are in charge of is regulating sodium levels in the blood system, and when they don’t function properly, it can result in high sodium levels in the bloodstream. A build-up like this can influence the system to retain more fluids and blood pressure, which will then put further pressure on their kidneys, further damaging them.  

Low Phosphorous

High levels of phosphorus can speed up the loss of function and kidney damage in cats, but when they’re kept low, you can slow down the process as well. When this happens, your cat should feel healthier overall and more energized. This is the reason why many cat foods come with a restriction on phosphorus levels.

Higher Moisture Content

Dry food can be a great option, but wet food comes with the extra benefit of providing additional moisture for your cat’s food. When your cat is suffering from kidney damage, dehydration can be a big problem due to the shortage of fluids from their damaged kidneys. Healthy cats don’t drink much water to begin with, so getting additional moisture from their food will go a long way against kidney disease. 


When you want to help your feline friend eat the right food for kidney disease, don’t choose non-prescription food or opt for a homemade diet. Always work with your vet to determine the best way to help your kitty by giving it food specifically formulated to help with its condition. Moreover, you must provide your cat with fresh water at all times to help it keep hydrated while it regains its appetite back with these great cat food for kidney disease.
