    Buyer’s Guide: How to Find the Best Cat Food for Kidney Disease in Canada

    Once you’ve received a kidney disease diagnosis, educating yourself on what that means and what the disease looks like is essential. So keep reading to learn more about kidney disease, the importance of phosphorus in your cat’s kidney-friendly diet, and other nutritional factors to consider.

    What Is Chronic Kidney Disease?

    Chronic Kidney Disease (CKD) is an ongoing kidney disease. You may sometimes hear it called renal disease or chronic renal failure (CRF). There is no timeline for CKD since it can be very gradual. It can take years for your cat’s kidney function to start failing.

    Healthy kidneys have many important roles, including filtering blood and producing urine. Since the kidneys have a large capacity to perform their functions, you may not begin seeing clinical signs of CKD in your cat until two-thirds of the kidneys are dysfunctional. This may mean that your pet’s kidneys have been deteriorating for months or years before the failure becomes evident.

    There are four stages of CKD. Knowing which stage your cat is in can help your vet determine the type of management (e.g., diet and food) that can slow the disease’s progression and minimize the risk of additional kidney damage.

    What Are the Symptoms of CKD?

    The two early warning signs of CKD include weight loss and poor coat quality. The problem is that these signs are often dismissed as typical signs of aging, so it can take a while for CKD to be officially diagnosed.

    Other symptoms of CKD include:
    • Bad breath
    • Lethargy
    • Depression
    • Increased thirst
    • Variable appetite
    • Vomiting

    The Role of Phosphorus

    You may have noticed that we discussed phosphorus levels throughout our buying guide. It is essential to keep your kitty’s blood phosphorus at a certain level to help slow the progression of CKD. VCA Animal Hospitals suggests that limiting the dietary phosphorus in CKD cats can reduce the effects of renal secondary hyperparathyroidism. This condition occurs if your cat’s parathyroid glands secrete excessive amounts of the parathyroid hormone.

    The recommended phosphorus range for cats with CKD is 0.3-0.6% on a dry matter basis. Most therapeutic kidney foods will fall below 0.5%, but not every cat will eat prescription food. That’s why our list above is comprised mainly of foods you can easily find that are still relatively low in phosphorus.

    Other Factors to Consider

    There are other nutritional requirements besides the phosphorus in your cat’s food.


    Diseased kidneys cannot excrete waste from the body through urine. Your cat’s body will tell them to drink more to compensate for the diluted urine. It is essential for you to provide your cat with fresh water at all times. Offering wet food can also help increase your cat’s water intake.


    VCA Animal Hospitals advises that a decreased protein intake can help slow the progression of kidney disease. This is because kidneys must filter out any waste products from the protein your cats eat.

    If your pet ingests less protein, their blood won’t contain as many waste products, decreasing the amount of work their kidneys need to do. However, your cat’s protein levels mustn’t drop too low, as their bodies may start breaking down their muscle mass to compensate.


    Diets high in sodium can increase your cat’s blood pressure and worsen kidney damage. Avoid offering your pet treats high in salt, such as deli meat and some commercial cat treats.


    Final Verdict

    Hill’s Science Diet Tender Tuna is Canada’s best overall cat food for kidney disease, thanks to its low phosphorus count and high-quality protein. Wellness Morsels Healthy Indulgence provides the best value for its low phosphorus count and antioxidant-rich recipe. Our premium choice is Hill Prescription Diet k/d Kidney Care, and although it’s pretty expensive, it’s prescription strength, so that’s to be expected.
