What To Look For In Cat Food For Kidney Disease

Low phos wet cat food (non prescription)

There are two keys things that people are looking at when picking cat food for Kidney Disease. The first is moderately low high-quality protein content. Of course, cats are obligate carnivores so this makes things tricky. They need meat and protein to survive.

The next is keeping the phosphorus content as low as possible. This is because high phosphorus accelerates renal failure. So in order to counteract that we try to restricted phosphorus. A great rule of thumb is to avoid foods that contain ground bone and instead use ground egg shell.

When looking for food how do you know if you are in the guideline of where you need to be for phosphorus? First off you need to find the foods nutritional information on a dry mater basis. Then you are looking for food ideally below 0.5% phosphorus.

Unfortunately a prescription kidney diet is the only way you will achieve this since minimum cat food standard state that on a dry matter basis phosphorus must be at least 0.5%. This means you are going for as close to that 0.5% as you can. As a rule of thumb I avoid anything that has a phosphorus over 1%. Where your max lies may be different depending on your cat. I know we will need to seek out lower phosphorus percentages as his stage of kidney disease progresses.

To quote Dr. Lisa A. Pierson, DVM

Fish can be high in mercury, high in PBDEs , high in phosphorus and can be very addicting. It is best to feed poultry-based diets to cats.

L-Carnitine supplementation aids in the development of lean muscle in this low-protein cat food.

Unlike some other kidney support solutions, this one begins with real meat. Additionally, this diet is grain-free, as it relies heavily on potatoes as the major source of digestible carbs.

Omega-3 fatty acids are provided via fish oil and flaxseed in this recipe . These beneficial fats stimulate the skins natural oil production and aid in the reduction of inflammation.

What Is The Best Non Prescription Low Phosphorus Cat Food

How To Redeem This Offer

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 bodys energy stores as well as cell growth and tissue repair. Because your cats 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 dont 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.

Should You Feed Your Cat Prescription Food For Kidney Disease

In summary, decades of research tell us that the best food for cats with CKD is one with the following qualities:

  • High caloric density
  • High quality or restricted protein
  • Low phosphorus levels
  • Increased B vitamins
  • Omega-3 fatty acids

Currently, prescription or therapeutic diets are the only foods that check all of those boxes at once. Frustratingly, those diets often have other not-so-great qualities.

Think high carbohydrate content, added sugar, and potentially low-quality animal by-products.

This gives you a few options.

You can hold your nose over the ugly parts of a therapeutic or prescription diet. You can opt for a non-prescription food that meets one or two of the above criteria. Or you can make CKD-appropriate food at home.

But youre also taking a riskhomemade food takes time and it can be hard to get everything right. If youre going to make homemade cat food for kidney disease, consider working with a veterinary nutritionist to ensure that you dont miss anything.

What Food Should I Feed A Cat With Kidney Disease

While changing your cat’s diet won’t necessarily cure kidney disease, it will ensure they have more of the support they need to process food correctly and stay as healthy as possible.

The best option is to feed your cat prescription food. Specifically suggested by your vet. Prescription foods are designed just to target the needs of a cat with kidney disease. Most prescription foods will include:

  • Low phosphorus and sodium levels
  • Increased B vitamins and other minerals
  • Fatty acids like Omega-3
  • High caloric density for better weight management
  • High quality and restricted protein

Your vet should be able to provide you with a direct insight into the kind of approved diets you can consider using. Alternatively, they may be able to teach you how to make your own kidney-focused foods at home, but this can be very time-consuming and expensive.

Its Paramount That Your Cat Eats Something

From Dr. David J. Polzin, DVM, PhD, DACVIMs 11 guidelines for conservatively treating chronic kidney disease:

In many or most dogs and cats with chronic kidney disease, death or euthanasia results directly or indirectly from starvation.

Feeding a cat with kidney disease is an exasperating dance between finding foods your cat will willingly eat and choosing foods that wont tax the kidneys. Your cat may enjoy their prescription food for a few weeks and then reject it. She might only eat a food thats high in phosphorus and refuse everything else.

To increase your chances of success, make dietary changes while your cat still has an appetite. Cats in the later stages of kidney failure might feel too sick to try something new.

If your cat becomes extremely finicky and refuses to eat multiple meals at a time, nutritional rules can go out of the window, at least temporarily. Cats with kidney disease might eat baby food, plain chicken breast, Temptations treats, liver, Fancy Feast, or bonito flakes. All of these are better than nothing.

Treating Kidney Disease In Cats

The Best Cat Food Low in Phosphorus

Chronic kidney disease 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
  • 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 cats food should help. The problem is low phosphorus cat foods arent always good.

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, lets take a moment to talk about prescription diets.

You Might Also Consider Supplementing Your Cats Diet With A Probiotic

When bacteria and endotoxins enter the gut, probiotics may help to perform enteric dialysis, taking on some of the detoxifying function that the kidneys have lost.

Azodyl is a synergized prebiotic and probiotic supplement designed for cats with kidney disease. The supplement contains patented strains of Enterococcus thermophilus, Bifidobacterium longum, and Lactobacillus acidophilus. The three probiotics are synergized with psyllium husk, a source of prebiotic fiber.

While its not clear that Azodyl will help, it does show some promise. If youre not willing to spend over $70 a bottle for the putative benefits of Azodyl, consider supplementing with another probiotic.

Talk to your veterinarian before giving your cat any supplements. Your vet can help you determine which supplements could help your cat and instruct you on how to give them.
