Phosphorus in Cat Food
Cats require a specific balance of nutrients in their diet for optimal health, just like we do. There are some differences in the necessary amounts for those nutrients, of course. Phosphorus is an essential mineral that helps support strong bones and teeth. It plays a role in managing the body’s energy stores as well as cell growth and tissue repair. Because your cat’s body only needs a certain amount of phosphorus, excess is filtered out through the kidneys.
The kidneys are designed to filter the blood, removing excess water and wastes to create urine which is then excreted from the body. Higher concentrations of waste products in the blood require the kidneys to work harder which can eventually lead to kidney disease. When the kidneys don’t work properly, it causes wastes to accumulate in the blood even further and can lead to a variety of health issues including hyperphosphatemia and the accelerated progression of kidney disease.
Treating Kidney Disease in Cats
Chronic kidney disease (CKD) is the progressive loss of kidney function over time. It is most commonly seen in cats between 10 and 14 years of age, presenting with symptoms such as:
- Loss of appetite
- Weight loss
- Increased urination
- Bad breath
Treatment for kidney disease in cats varies depending on the severity. In some cases, the first step is to flush out the kidneys with intravenous fluids to stimulate their function and to restart waste removal. Treatment may also involve additional medications to control symptoms as well as proper nutrition to help the cat heal and recover.
Many veterinarians recommend a low phosphorus cat food for kidney disease. The idea is to reduce the workload on the kidneys to help slow the progression of the disease. Phosphorus is one of the waste products that builds up in the kidneys, so reducing the phosphorus content of your cat’s food should help. The problem is low phosphorus cat foods aren’t always good.
Cat foods designed to be low in phosphorus are often low in protein as well since protein contains significant amounts of nitrogen and phosphorus. The issue here is that a cat’s body is biologically adapted to utilizing nutrition from animal sources rather than plants – protein is their primary source of energy. On top of that, your cat’s body has a limited ability to control its own protein metabolism. If the protein content of your cat’s diet is reduced, he’ll likely end up metabolizing a similar amount of protein anyway and some of it may come from his own tissues.
At this point, you may be wondering whether what the best food for cats with kidney disease actually is. Before we get to our recommendations, let’s take a moment to talk about prescription diets.
Is Prescription Cat Food Necessary?
When it comes to specific health problems like kidney disease, many veterinarians recommend prescription-only cat foods. What you need to realize about veterinary pet foods, however, is that they don’t always contain therapeutic ingredients. They may contain different levels of certain nutrients and are marketed for specific health problems, but they aren’t a substitute for veterinary treatment.
In many cases, prescription cat foods are made with low-quality ingredients as well. If you take a look at the label for big brands like Royal Canin and Hill’s Science Diet, you’ll see heavy use of corn, wheat, and soy ingredients. In fact, many recipes don’t even list an animal protein as the first ingredient. Though low phosphorus prescription cat food does exist, you have to wonder whether the low quality of the ingredients cancels out the benefits of a reduced phosphorus diet.
What Should You Look for in a Good Cat Food?
If you want to support your cat’s health, a high-quality nutritious diet is the way to go. If your cat has severe kidney disease, he needs veterinary treatment – a prescription diet won’t necessarily solve the problem. Your cat may be better off with a quality cat food made from wholesome, natural ingredients that’s easy to digest and provides for his nutritional needs. The higher the quality the food, the easier it is to digest which means fewer waste products for your cat’s kidneys to filter out – that means less work they have to do. Either way, a high-quality diet will benefit your cat’s long-term health and wellness.
After talking to your veterinarian, you may decide to switch your cat to a better food. If that’s what you want to do, here are some things to look for in a good cat food:
- Real animal protein as the first ingredient. Animal protein should be the foundation of your cat’s diet and definitely the first ingredient in his food. Look for real meat, poultry, or fish as the first ingredient and ideally two out of the first three.
- Healthy animal-based fats. In addition to protein, your cat needs healthy fats in his diet and they too should come from animal sources as much as possible.
- Rich in moisture. Moisture essential to keep your cat hydrated and to keep his kidneys functioning. Wet cat food is higher in moisture than dry food and may be a better option for cats with kidney disease. It also tends to be more palatable which can help with low appetite.
- No artificial additives. Cats with reduced kidney function may have trouble filtering wastes out of their blood, so avoid any cat food that contains artificial additives.
- High-quality natural ingredients. The more digestible your cat’s food is, the better. Look for natural whole food ingredients instead of by-products and fillers.

Frequently Asked Questions
- Is phosphorus good for cats? Yes, phosphorus is an essential mineral required for optimal health. It plays a role in balance with calcium to support healthy bones and teeth as well as other essential functions. It’s important to recognize, however, that excess phosphorus in the diet can be problematic, especially for cats with kidney disease who have trouble filtering the excess out of their blood.
- What is the best food for cats with kidney disease? Many veterinarians recommend low phosphorus cat food for kidney disease. Phosphorus doesn’t directly cause kidney disease, but many cats with kidney disease end up with high phosphorus levels because the kidneys have trouble filtering the blood.

- Is a prescription or non prescription low phosphorus cat food better? It’s up to you and your veterinarian whether you choose a prescription or non prescription low phosphorus cat food for kidney disease. You may not even need to choose a low phosphorus cat food at all. Depending how your vet is treating your cat’s kidney disease, it may be better to simply choose a high-quality, nutritious diet that will be easy for your cat to digest. Real animal protein with limited carbohydrate content is recommended and you may want to consider a canned food recipe.
- Is wet food better for cats with kidney disease? Wet food is typically a better option for cats with kidney disease than dry food. For the most part, wet foods are higher in protein and lower in carbohydrate content than dry food, though it depends on the recipe. Canned food is also rich in moisture which can be beneficial for cats with kidney disease. The most important thing, however, is the quality and digestibility of the food as a whole.
- Can cats recover from kidney disease? It depends on the severity of the disease and how quickly you catch it.
