Recipes for cats with kidney disease
for use with CompleteMe Renal Feline
These recipes have been formulated to suit the needs of adult cats with kidney disease. They have been formulated by our founders (who are Board Certified Veterinary Nutritionists®) to be appropriate for early renal disease (IRIS stage 1 – 2) or advanced renal disease (IRIS stage 2 – 4), and can be prepared with raw or cooked proteins. Please see below for a table with information on the phosphorus content of the recipes, and comparison to commercial renal diets for cats. We recommend using the filters to select recipes that are appropriate for your cat’s medical needs.
To make these diets, you will need CompleteMe Renal Feline, which provides essential vitamins, minerals and amino acids. It also contains beneficial ingredients for kidney support, such as omega-3 fatty acids from marine algae, betaine and prebiotics to maintain body weight and support the microbiome, and lutein to increase antioxidant activity in the kidney.
Can I just feed raw or cooked meat plus the supplement?
We completely understand how convenient this would be! However, it really doesn't produce an ideal diet, nor is it personalised in any way to the stage of disease.
For example, raw chicken thigh (skin on) plus a low phosphorus meal completer is often recommended as an appropriate choice for cats with CKD. What is interesting about this is that, yes, it does produce a very low phosphorus diet, but it also produces a very low protein diet as well – 77 grams of protein per 1000 kcal ME. This is actually significantly lower than most commercial early renal diets like Purina NF Early Care or Royal Canin Early Renal, which have ~95 to 110 grams of protein per 1000 kcal ME.
For more advanced cases, protein can be further restricted, but again, it's preferable to decide this based on the stage of disease, age of the patient, and any other co-morbidities.
What is also important to understand is that research suggests that severe dietary phosphorus restriction may increase the risk of hypercalcaemia developing in some cats with early CKD, so early renal diets are typically a bit higher in phosphorus than advanced renal recipes. Changing to a moderately phosphorus-restricted diet can resolve hypercalcaemia in some cases.
Why are there carbohydrates like rice or sweet potato in some of the recipes?
For cats with early renal disease (IRIS stage 1 or early stage 2), there are recipe options with either no to very little carbohydrate. By necessity, these recipes are very high in fat, so they may not suit all cats. For cats with concurrent diabetes mellitus and/or pancreatitis, they may be ideal.
There are also some recipe options with low to moderate carbohydrate, and a more moderate fat content. Overweight or obese cats may do better on these recipes, and some cats with gastrointestinal disease may also do better on a moderate fat diet.
For cats with advanced kidney disease (IRIS stage 2 to IRIS stage 4), the provided recipes have greater protein and phosphorus restriction. This necessitates the inclusion of some carbohydrate, so these recipes are typically lower in protein, very high in fat, and moderate to low in carbohydrate. These recipes still generally have 9-20% calories from carbohydrate, so there are still some very low carbohydrate options suitable for cats with diabetes.
