Kidney Disease in cats is becoming more prevalent, and it can affect cats of any age and breed. Treatment for kidney disease varies, depending on how severe it is, but the good news is that diet changes can often help. Proper nutrition, specifically a low-phosphorus diet, can help reduce symptoms and slow or stop kidney disease from progressing.

Because proper nutrition is vital for cats with kidney disease, it may feel overwhelming to find the right brand. Cats in the early stages of kidney disease can thrive from a high-quality ingredient food that is readily available, but some special recipes require a prescription from the vet.1

This article reviews our 10 best cat foods for kidney disease. With over-the-counter products and prescription options, our guide also has a buyer’s guide to help you find the best food for your cat.

    Buyer’s Guide: Choosing the Right Food for Cats with Kidney Disease

    Sadly, there is no cure for kidney disease, so carefully managing your cat’s diet is a top priority. When choosing a cat food that is suitable for a cat suffering from kidney disease, phosphorus restriction is crucial and the simplest way to reduce blood phosphorus levels in cats is to limit their intake.

    Phosphorous

    Phosphorus is expelled through the urine made by the kidneys, and if kidney function is compromised, phosphorus levels will increase. If kidney disease is in its early days, phosphorus can be somewhat restricted, and most cats can thrive on a quality over-the-counter food, but more serious and advanced cases will require a more substantial restriction of phosphorous. Severe cases could also benefit with medication that binds to phosphorus in the intestinal tract to help limit its absorption.

    Protein

    Typically, foods that are high in protein are also high in phosphorus. Meals for cats with kidney disease should always contain the highest quality protein possible so that your cat gets the most benefit, while having a minimal negative effect on its kidneys. Look for quality animal-based protein sources, avoiding proteins that are a byproduct of the manufacturing process.

    It can be difficult to determine the appropriate protein level for your cat’s food. Too much protein increases the amount of urea and phosphorous the body must eliminate, while cats with kidney disease may suffer from more severe muscle wasting with too little protein. Consulting your vet is the safest option when determining how much protein your cat needs.

    Moisture Levels

    Dehydration is a problem for cats with kidney disease, and because canned food contains more water than dry food, canned food is the recommended choice. If your cat refuses to eat canned food, choose a high-quality dry food and do everything you can to encourage your cat to drink plenty of water.

    Dry food may also be a better option for some cats as canned food is not as calorically dense as dry food, therefore some cats may not maintain their weight. Dry food is a better option if the owner is willing to make up for the loss of water by subcutaneous fluid administration and if your cat has a higher calorie intake after changing foods.

    If your cat is losing weight on a diet specialized for kidney disease, the food is not meeting your cats’ nutritional needs, whether or not it seems to be effective for your cats’ kidneys. The solution could be as simple as trying a new brand.

    Any new cat food, including low-phosphorus food, should be introduced gradually by mixing it in with your cat’s regular food.
