Purchasing Guide for Best Low Phosphorus cat Food

Phosphorus is a mineral that is required in feline diets. However, excessive phosphorus levels might lead to many problems in cats with renal disease. Therefore, it is vital to learn how to choose a healthy, low-phosphorus cat food for your special needs cat.

Phosphorus Contained In Cat Food

Phosphorus is a macromineral that is required for the growth and development of bones.

All cats require enough phosphorus in their diet to maintain a healthy skeletal structure. 

 Kittens, per se, require much greater phosphorus content in their food for growing a healthy skeletal system.

Although mature cats’ phosphorus requirements decrease with age,  phosphorus deficiencies can still cause serious health concerns. Nonetheless, there are several cases in which an overabundance of phosphorus can be detrimental to cat health.

Which Cats Require a Diet Low in Phosphorus?

Your cat’s kidneys assist in maintaining a healthy mineral balance in his body.

However, when renal function is impaired, excess minerals can accumulate in the organ.

These minerals can cause the kidneys to become overloaded, resulting in stones and, eventually, renal failure.

According to research, phosphorus is quite stressful on damaged kidneys. As a result, providing low-phosphorus Cat meals is critical for managing chronic renal illness.

[3]   

Consider the Following When Choosing a Low Phosphorus Cat Food

Only a few cat food manufacturers provide pet food with safe phosphorus levels to support renal health. Due to the potential danger of phosphorus deficiency, it is essential to take these considerations into account while selecting the optimal food for your cat.

Content of Phosphorus

The majority of dry cat meals include roughly 2% phosphorus. This satisfies the nutritional needs of an average healthy cat but may be detrimental to kittens with impaired renal function.

The majority of renal care cat diets include less than 1% phosphorus. A phosphorus level of 0.6 percent is optimal for the majority of cats with renal problems.

Source of High-Quality Protein

Additionally, a high protein level might be dangerous to the health of the kidneys.

However, your cat needs an appropriate supply of amino acids to maintain muscular health.

While real meat may not be the first component, search for a kidney care formula that includes a source of high-quality animal protein, such as whole chicken.

Depending on the severity of your cat’s renal disease, your veterinarian may suggest a reduced protein diet. These are almost typically prescription diets that require veterinary approval.

Proteins with a Low Phosphorus Content

While animal proteins should form the basis of a carnivore feline diet, many types of meat are rich in phosphorus. Premium meats such as beef and liver are examples of proteins with a high phosphorus concentration.

Duck, chicken, and turkey are three of the most often utilized low-phosphorus protein sources in cat diets. You should also select diet that is free from animal by-products or has a restricted amount of byproduct as these components can also contain high levels of phosphorus.

Potassium

Not all minerals are detrimental to kidney health. Adequate potassium levels are critical for renal function and low levels may have a role in renal failure.

Numerous renal care formulas incorporate potassium supplementation in their content.

This mineral can aid in filtration and help with the gradual rebuilding of impaired kidneys.

Calcium

Rather than directly lowering phosphorus, some renal care cat diets contain phosphorus binders, which inhibit your cat’s body from absorbing the mineral.

These binders bind to phosphorus in the digestive tract before it is absorbed from the food, enabling excess phosphorus to pass through.

Calcium is the most often used binder for phosphorus. It is also a necessary mineral for cats, as it is necessary for bone formation. Calcium supplementation can assist in limiting the amount of phosphorus that enters your cat’s kidneys.

High Fiber

Prebiotic fibers contribute to the formation of important element which is nitrogen trap. Nitrogen traps, like phosphorus binders, act in a similar manner. However, rather than trapping phosphorus, these traps help the kidneys in reducing their burden by addressing protein waste.

Protein digestion byproducts frequently pass through the kidney and are excreted in the urine. However, nitrogen traps route these molecules to the colon. Therefore, choose a kidney care formula that contains a high fiber content.

Prescription vs. Over-the-Counter Cat Food

Chronically ill cats may require therapeutic nutrition and customized diets to control their ailments. Prescription diets are the most secure approach to ensure that your beloved friend’s food meets his unique nutritional requirements.

Veterinary approval is required for prescription cat meals. And as phosphorus is critical for your cat’s health, I recommend choosing low-phosphorus formulations only if they have been recommended by your veterinarian.

Clinical research guarantees that all veterinary diets are safe and effective for cats with specific health issues. The best approach to ensure that your cat receives the nutritional assistance he requires is to work with your veterinarian to develop a tailored diet.

Conclusion

A low-phosphorus diet can be a very beneficial nutritional aid for cats with renal disease.

The chronic renal disease greatly impairs the quality of life of your pet. and, excessive phosphorus can overburden the already-weak kidneys, resulting in serious consequences.

As the best overall food low phosphorus diets for cats, I recommend Blue Buffalo Natural Veterinary Diet K+M Kidney + Mobility Support Grain-Free Dry Cat Food
