Importance of Right Food for Cats with Kidney Issues

With a well-planned dietary management strategy, you can help alleviate the symptoms of kidney issues in your cat. Sure, you cannot undo the damage that is already done. However, with the right diet in place, you can prevent any future adversities that might happen.

It is the best-known way to decrease the progress of the disease, minimize symptoms, & give the cat a chance to live their best lives.

What to Look for in Cat Food for Kidney Diseases?

It would help if you kept in mind several things when looking for the right cat food for your feline suffering from kidney issues. First, when the dietary protein breaks down indigestion, it produces waste. A healthy kidney can filter out the waste & pass it through poop and straight into your cat’s litter box.

However, as your pet starts to lose its kidney function, the process of waste removal becomes incredibly difficult.

Instead of being passed through the cat’s body, the waste remains in your cat’s bloodstream. This leads to an increase in the blood urea nitrogen (BUN) levels in cats that suffer from CKD or Chronic Kidney Disease.

To reduce the BUN levels, felines with CKD are given food items with protein restrictions.

However, the key is not to deprive your cat of protein content, as it can lead to a rapid decrease in muscle mass along with poor physical stature.

As opposed to cutting down the calorie level to 20 percent from protein, pet parents can choose to give their cat a moderate level of low-waste, highly digestible protein from top-notch animal sources.

Simply put, you should ensure that your cat feels better and not worse with a diet change. A protein-restricted diet would help your cat feel better to a certain point.

However, it would lead to rapid muscle loss & weakness. Before you opt for a protein-deficient diet, make sure you weigh the pros and cons of doing the same.

Should You Select a Diet with Low Phosphorus Content for Your Cat?

As your cat’s kidney function starts to decline, phosphorus doesn’t filter out properly. This leads to a rapid buildup of phosphorus in your cat’s bloodstream. As this happens, your pet will start feeling ill & the kidney function will decline even more.

A proven way to prevent this problem is by bringing down the phosphorus content in your feline’s diet. An ideal food routine for your cat that suffers from CKD should contain 0.5 percent or less phosphorus content in dry matter.

Opt for Low Sodium Levels in Cat Food

As is known, excessive consumption of sodium can enhance blood pressure & worsen your cat’s kidney issues. Therefore, most veterinarians suggest that cats with renal issues should consume a diet short in sodium level. You must also avoid giving your cat treats that are high in sodium levels, such as salty cheese or luncheon meat.

Opt for a Diet with Omega-3 to Reduce Inflammation

Most cats that suffer from kidney diseases develop kidney inflammation or nephritis. So, make sure you select supplements with anti-inflammatory components along with omega-3 acids like DHA and EPA.

The fatty acids feature the ability to bring down inflammation while helping the cat feel better.

Humans & other animals tend to benefit from plant-based omega-3 from sources such as flaxseed oils. However, felines can only use the ones that come from animal fat. A good source of such healthy fatty acids includes fish oils such as menhaden oil, sardine oil, krill oil, and salmon oil.

Pet parents can also opt for green-lipped mussels. Apart from being a rich source of omega-3, they also contain concentrated ETA fatty acids.

You can also opt for supplements dedicated to supplying your cat with the daily requirements for omega-3.

Don’t forget those vitamins

Cats that suffer from kidney disease tend to urinate a lot. This leads to a rapid loss of crucial vitamins from their body. It is especially true for vitamin B. Vitamin B deficiency can lead to appetite loss and poor health.

As pet parents, you need to seek a diet fortified with B-complex vitamins to ensure your cat always thrives and doesn’t face any deficiency. In addition, it is essential to support your cat’s muscle functions & nervous system well-being.

Simply put, your cat with kidney disease should be given a diet with given qualities:

  • Restricted or high-quality protein
  • High-calorie density
  • Low level of phosphorus
  • Higher level of vitamin-B
  • Limited sodium levels
  • Omega-3 from animal sources
