What Constitutes a Low Protein Diet for Cats?

Normally, kittens and adult cats need almost 25 to 30% protein in their diets. This amount is necessary to maintain muscle mass and also provide your pet with energy to remain active all day.

However, at times, such high protein levels can lead to enzyme fluctuations in your cat which, in turn, can impact its renal, liver, and heart function. In older cats, over time, this can result in kidney related issues, liver disease, and/or congestive heart failure.

For managing these conditions and preventing the disease from worsening, your vet might place your cat on a low protein diet for cats.

Low protein diet for cats means any cat food, wet or dry, which has controlled levels of protein in it.

Your vet might prescribe specially made veterinarian food with reduced or controlled protein amounts.

Based on your cat’s exact health requirements, your cat could benefit from a food with 10% to 12% protein per serving.

It is very important to understand that ‘low protein diet for cats’ does not mean ‘NO’ protein.

You cat still needs protein to carry out bodily functions and for optimal wellbeing.

To summarize, low protein cat food means any food having controlled or reduced protein levels or easy-to-digest and easy-to-metabolize protein levels.

Low protein diet for cats has a lower percentage of protein as compared to standard cat food available commercially.

If your cat has a confirmed diagnosis of liver/heart/kidney issues, your vet might prescribe low protein cat food containing 10-12% (or even lower) protein levels. Standard cat food contains nearly 30% protein.

When do Cats need Low Protein Cat Food?

Cats with kidney disease (CKD or chronic kidney disease), interstitial inflammation, fibrosis, and obesity, liver disease, heart disease, congestive heart failure, cardiac issues, severe allergies, pancreatitis, etc. sometimes benefit from low protein diets for cats.

However, there is a great deal of controversy in this matter and nothing is black and white.

First of all, there are very few studies on this subject.

It is very important to remember that cats are primarily carnivores. In the wild, their diets constitute nothing but protein.

So, it does not make much sense in limiting their animal protein intake too much.

Then there are other factors that need to be considered while treating CKD, liver issues, renal function impairment, and cardiac diseases in cats.

You see, protein in food is not the only thing that will impact your pet’s health. You also need to consider factors like phosphorus and sodium as well as the balance of electrolytes in the food.

There is no doubt that nutrition and diet are extremely important for the overall health well-being of your cat.

Therefore, when one is treating a serious health issue like CKD or impaired renal function in cats, one must take the entire health profile of the pet into account before finding the best diet for her/him.

What are Some of the Benefits of Low Protein Diet for Cats?

No two cats are the same.

While some cats with kidney issues do well on low protein diets, many do not.

It may require multiple tests along with trial and error to find the best low protein cat food that also has controlled/lower sodium and phosphorus levels.

Having said that, a small percentage of cats with the aforementioned health issues have benefitted from reduced protein or controlled protein levels in their diet.

Such low or controlled protein levels in cat food work in the following ways:

• High-quality low protein cat food could reduce the stress on your cat’s vital organs like kidneys and liver.
• It can sustain adequate nutrition in ailing cats that are too sick to eat.
• Top-rated low protein cat food for kidney disease could modify/slow down/halt the progression of CKD, liver diseases, allergies, heart-issues, etc.
• It could reduce the accumulation of waste products in the blood – a common sign of impaired renal function.

By selecting the best low protein cat food, you can make sure that your pet receives the balanced nutrition it needs for optimal health.

What Features Should You Look for When Selecting the Best Low Protein Cat Food?

Kidney, heart, or liver disease in your cat can be quite serious but with the right food and loving care, your pet can live comfortably for years to come.

Here are some features to consider when looking for the best low protein cat food:

1) Contains controlled levels of highly digestible protein

Completely eliminating your cat’s dietary protein can result in reduced muscle mass and excess weight loss.

Instead, look for low protein cat food with controlled protein levels of highly digestible protein. Look for energy dense nutrition from high-quality low protein cat food brands.

2) Has lower levels of sodium and phosphorus

It is very important to feed your cat a diet lower in sodium and phosphorus. Increased levels of these electrolytes can further tax your pet’s already-impaired renal function.

3)  Is tasty and nutritious

A common side effect of impaired renal and kidney function is an acidic stomach which causes nausea, vomiting, and lack of appetite.

Select a high-quality low protein cat food that is also tasty and stimulates your pet’s taste buds.

Foods with healthy oils and taste-bud stimulating ingredients like herbs, fruits, and vegetables combined with easy-to-digest protein like chicken and/or fish can help.

Conclusion

The best low protein cat food can help cats diagnosed with certain health issues like chronic renal failure, kidney disease, liver problems, and heart-related conditions.
