What’S The Best Cat Foods For Kidney Disease ?

Chronic renal disease is one of the most frequent disorders affecting domestic cats, and it is a terrible fact that many cat owners will have to face.

The good news is that symptoms can be reduced and the progression of this condition can be slowed and controlled with adequate nutrition, notably a low-phosphorus diet.

The only way to know if your cat has kidney illness is to get an official diagnosis from a vet, and many of the diets that can help with the symptoms will also require a prescription from the vet.

This is because feeding your cat a low-phosphorus food if they do not have kidney problems can be risky. Before embarking on a specific diet for your feline companion, seek confirmation from your veterinarian.

Finding the perfect diet for your cat can be stressful because proper nutrition is so important for controlling kidney illness.

Fortunately, you've arrived to the correct place! In this post, BestForPets (bestforpets.org) has compiled a list of the best cat foods for kidney disease, along with detailed reviews to help you select the finest diet for your kitty.

Buyer's Guide: Choosing The Best Kidney Disease Cat Food (Low Phosphorus)

Acute renal illness can strike cats of any age or breed at any time. The actual etiology of kidney illness in cats is unknown, however it can be caused by a variety of reasons, including toxins, shock, and bacterial infection.

It is frequently curable with diligent treatment. Chronic renal disease, on the other hand, is more common in elderly cats and develops gradually over time.

A special diet can help control the disease and significantly increase your cat’s lifespan, but it will not reverse the sickness.

Whatever the reason, the disease is defined by your cat’s kidneys failing to adequately eliminate waste items and excreting them in their urine, specifically phosphorus, salt, and protein.

This is why low-phosphorus foods are critical for cats with kidney disease.

What to look for in diets for kidney-diseased cats

Because there is no treatment for renal illness, the only way to manage it is through medicine and proper nutrition control for your cat.

It is accomplished through the use of a customized diet low in phosphorous, protein, and sodium, as the disposal of these is what is limited by renal disease.

With this in mind, you should look for food that contains the following ingredients in it for your cat.


The diet you buy must have relatively low protein levels, as protein breakdown might produce excessive waste products that must be dealt with by your cat’s kidneys.

While protein is essential for your cat’s health, they will require a reduced protein intake or, preferable, a low concentration of high-quality proteins.

Because they are getting less protein, it is critical to provide them with the finest protein source possible.

Phosphorus deficiency

High amounts of phosphorous in your cat’s circulation accelerate kidney damage and loss of function, while low levels halt the damage.

This will also make your cat feel more invigorated and happy in general, which is why most renal disease meals include low phosphorus levels.

Low in sodium

The kidneys are also in charge of salt management in your cat’s circulatory stream. If they are not operating properly, they will naturally have excessive sodium levels in their bloodstream.

This buildup can cause higher blood pressure and fluid retention, putting even more strain on the kidneys and continuing the problem.

Moisture content is high

While dry foods are excellent, wet canned foods provide additional moisture to your cat’s diet. Dehydration is a serious issue in cats with damaged kidneys due to a loss of fluid balance from the kidneys.

Because even healthy cats drink relatively little water, this can aid in the treatment of kidney illness.


Cats with renal illness frequently lose their appetite and thus body weight. This is why excellent and appealing-smelling food is essential since it encourages your cat to consume.


Hill’s Prescription Diet Kidney Care is the best cat food for cats with kidney disease.

This product contains Enhanced Appetite Trigger (E.A.T.) technology, which stimulates the appetite and so increases calorie intake, as well as carefully controlled phosphorus levels, low salt, and high quantities of key amino acids to help develop and maintain muscle.
