Buyer's Guide: How to Select the Best Kidney Disease Cat Food

https://www.youtube.com/watch?v=bH8N-oLZe10

Choosing the right cat food for a cat with kidney disease can be overwhelming due to the plethora of options available.

Specially formulated commercial cat food for kidney disease can significantly improve the cat’s health and delay the progression of the disease.

1. What exactly is Kidney Disease?

Kidney disease occurs when the kidneys fail to remove waste from the bloodstream, leading to a buildup of toxins that can cause significant health issues.

Although kidney disease is typically incurable, it can be managed with a specialized diet and other treatments.

2. Nutrition

Nutrition plays a critical role in managing kidney disease in cats. Cats with kidney disease require specialized nutrition that is low in protein, salt, and phosphorus, and high in omega-3 fatty acids.

A diet tailored to a cat’s specific nutritional needs can help control the clinical signs of kidney disease, improve their quality of life, and slow the progression of the disease.

Cats with kidney disease need more water to support their kidneys, and canned food is the best way to provide this due to its higher moisture content.

Additionally, a low protein diet can help reduce the amount of work required by the kidneys to filter out protein waste products.

Sodium and phosphorus should also be moderated to assist the kidneys in filtering out excess salt and to decrease the growth of the disease.

3. Can Kidney Diseased Cats Eat Chicken?

While chicken can be included in a cat’s diet, the protein levels must be kept low. However, cooked or raw chicken should never be given to cats with kidney disease.

Eggs can also be beneficial as they are low in phosphorus, but they must be combined with other foods to ensure that the overall diet is low in protein.

In conclusion, a specialized diet that meets a cat’s specific nutritional requirements can help manage the clinical signs of kidney disease, improve their quality of life, and slow the progression of the disease.

Working with a veterinarian to develop a nutrition plan that is appropriate for the cat’s needs and providing the necessary treatments to manage their condition is essential.

4. Price

Low phosphorus cat diets are generally more expensive than conventional cat foods due to higher-quality ingredients and smaller production quantities.

However, price is not always a reliable indicator of product quality, so it’s important to examine the product label and reviews before making a purchase. To save money, you can also look for discounts, coupons, and bulk deals.

5. Type of food

Low phosphorus cat foods are available in both wet and dry varieties. Wet food has higher moisture content and is easier to digest, which can help cats with kidney disease avoid dehydration and constipation. Dry food has lower moisture content and is more convenient to store and feed, but it can increase the risk of dehydration and urinary tract infections in cats with kidney disease.

Consult with your veterinarian to determine the optimal type of food for your cat, and consider a mix of wet and dry food to balance the advantages and disadvantages of each.

6. Quality of ingredients

Low phosphorus cat food should be made with high-quality, natural, organic, grain-free, or limited-ingredient ingredients. Avoid products that contain artificial colors, flavors, preservatives, additives, by-products, or other harmful substances. Look for products where meat is listed as the first ingredient, as cats are obligate carnivores that require animal protein for optimal health.

7. Phosphorus content

According to guidelines from the International Renal Interest Society (IRIS), low phosphorus cat food should have a phosphorus content of less than 0.5% on a dry matter basis (DMB). You can calculate the DMB phosphorus content by dividing the phosphorus percentage by the product’s dry matter percentage.

For example, if a product has 10% moisture and 0.4% phosphorus, the DMB phosphorus content would be 0.4 / (100 – 10) = 0.44%, which falls within the acceptable range.

8. Protein content

On a dry matter basis (DMB), low-phosphorus cat food should have a moderate protein content of around 30%. Protein is crucial for feline growth and maintenance, but excessive protein can strain the kidneys and contribute to the accumulation of waste products in the bloodstream.

It’s important to avoid products that contain too little or too much protein, as they can lead to malnutrition or metabolic acidosis in cats with kidney disease.

9. Sodium content

Low-phosphorus cat food should have a sodium content of less than 0.3% by weight (DMB). Sodium plays a vital role in maintaining fluid balance and blood pressure in cats.

However, excessive sodium can contribute to hypertension and edema in cats with kidney disease. It’s important to avoid products with high sodium content, as they can worsen your cat’s condition and increase the risk of heart failure.

10. Calcium-to-phosphorus ratio

The calcium-to-phosphorus ratio in low phosphorus cat food should be approximately 1:1 or slightly higher. Calcium and phosphorus are both crucial for feline bone and muscle health, but they need to be balanced to prevent mineral imbalances and bone disorders in cats with kidney disease.

It’s important to avoid ratios that are too low or too high, as they can lead to hypocalcemia or hypercalcemia in cats with kidney disease.

11. Label reading

Low phosphorus cat food labels should be clear and accurate, providing all relevant information about the product’s ingredients, guaranteed analysis, feeding instructions, etc.

It’s important to carefully read and compare labels of different products to understand their nutritional values and suitability for your cat. Additionally, check the product’s expiration date and storage conditions to ensure its safety and freshness.

12. Customer feedback

Low-phosphorus cat foods should have positive customer reviews from those who have tried them. It’s important to read online or offline reviews and evaluations of various products to assess their strengths, weaknesses, effectiveness, palatability, and more.

Additionally, look for testimonials or endorsements from veterinarians or other professionals who have recommended these products.

FAQs

1. How can you reduce phosphorus in cat food?

Consider adding fresh, low-phosphorus foods like watermelon, apples, bananas, green beans, carrots, broccoli, zucchini, and blueberries to your cat’s diet.

Avoid high levels of phosphorus found in cereal grains or animal products such as rawhides, jerky treats, and real bones.

2. What are the signs of kidney disease in cats?

Signs of kidney disease in cats include decreased appetite, weight loss, anorexia, vomiting, halitosis, excessive urination, and excessive thirst.

3. What causes kidney disease in cats?

Contributing factors to kidney disease in cats include dental disease, free feeding, breed, aging, low body weight, hyperthyroidism, and dehydration.

4. How long can a cat with kidney disease live?

The progression of the disease is unpredictable. Many owners may choose euthanasia due to the time and financial burden of caring for a cat with kidney disease.

The prevalence of kidney disease increases with age, with 10% of cats over 10 and 31% over 15 experiencing kidney disease. Feeding your cat a kidney-protective diet can improve their lifespan and overall health.

5. What are the benefits of a kidney disease diet?

A kidney disease diet can increase survival time in cats and reduce the risk of kidney failure. Improving your cat’s health can also help reduce financial costs related to medical treatment and result in fewer trips to the vet.

Conclusion

Hill's Prescription Diet k/d Kidney Care Canned cat food is the best choice for cats with kidney disease.

It contains high-quality protein in low amounts, as well as low levels of phosphorus and sodium, which is important for cats with kidney problems.

It also provides additional nutrients, such as omega fatty acids.
