If you ask the average veterinarian what cats commonly come to vet clinics for, kidney issues will be at the top of the list. Unfortunately, our feline friends are naturally prone to poor kidney function, especially if they’re older or on a strictly dry food diet. Older cats are more vulnerable to cancers, infections, and diseases that can affect the kidneys, while feeding a kibble-only diet can dehydrate cats and put stress on their kidneys over time.
If your cat is showing signs of kidney dysfunction (frequent urination, excessive water drinking, weight loss, bad breath, dull fur, lack of appetite, weakness, etc.), then it’s a good idea to bring them into the vet as soon as you can. Kidney problems can easily go unnoticed for years until the kidneys start failing, so stay observant for any signs of illness or discomfort in your cat.
If your cat has kidney problems, then your vet may recommend switching them to a low-phosphorus (and possibly low-sodium and/or low-protein) food. This is because damaged kidneys have a hard time getting rid of extra phosphorus. High phosphorus levels can pull calcium out of the bones, making them weak and brittle. Meanwhile, controlling sodium and protein intake can help reduce the workload on the kidneys and balance your cat’s blood pressure.
Thankfully we have plenty of kidney-friendly kitty foods in our store. Generally, any food with a phosphorus level below 0.4% is considered low phosphorus. Most low-phosphorus diets will be in the form of wet food or raw food. It’s hard to find cat kibble that is low-phosphorus because of the way that kibble is cooked and also because of how many carbs are found in kibble. Plus, the rich moisture content of wet and raw food helps to flush your cat’s urinary system and promote toxin removal in a way that kibble can’t.
Without further ado, here's a list of delicious and nutritious low-phosphorus cat foods that you can find on our shelves:
