Meowmie is compiling various home-made recipes for Chronic Renal Failure or Chronic Renal Insufficiency kitties and calculating their phosphorus and protein content.  The nutrition data and tool used for all the calculation is the USDA Nutritional Data Tool. 

http://www.nat.uiuc.edu/mainnat.html


Although the nutrient profiles for foods in the USDA data base are "averages" and should not be taken as the exact representation of one particular food or recipe, it does give us a fair idea of what is in the food and allows us to cmpare "apples with apples" so to speak. 

Let's start with one of Hill's home-made version of thie K/D diet:

Hill’s Homemade (liver and egg) K/D

454g (1lb)    Chicken Liver (you can use beef or pork liver)
2 Cups        Boiled white rice
2 Lrg          Hard boiled eggs, finely chopped
1 Tbsp        Vegetable Oil
1 tsp          Calcium carbonate or ground eggshell
1/8 tsp       Salt substitute (potassium chloride)
                 Water for processing

Calories – 1427.15
Add:
Protein – 131.73g
Fat – 53.35g
Carb – 94.49g
Fiber – 1.26g
Ash – 7.27g

Total:  288.1g x 1000 = 288,100

Phosphorus:  1730.84mg / 288,100mg = 0.006007  x 100% = 0.6007%
Protein:   131.73 / 288.1g x 100 = 45.72%

Both the phosphorus and protein load are acceptable, but Vit A and D load may be too high becuase of the amount of liver used in this recipe.  Vitamin A alone is a whopping  75,130.94 IU !!!  (RDA is 2272 IU/lb DM).

Let's look at one of Strombeck's renal recipes:

Dr. Strombeck's Chicken and Rice Diet
(low-protein, low-phosphorus, normal potassium, normal sodium diet providing 46.4 grams protein/1000 kilocalories)
1/4 cup cooked chicken breast
1/2 ounce clams, canned, chopped in juice
1 cup rice, long-grain, cooked
1 Tablespoon chicken fat
1/8 teaspoon salt substitute-potassium chloride
1 calcium carbonate tablet (400 milligrams calcium)
1/4 multiple vitamin-mineral tablet
[author recommends a supplement prepared for humans with allergies; without vitamins A or D]
1/10 B-complex vitamin-trace mineral tablet

Calories:  406.59
Add:
Protein –  20.77g
Fat – 14.95g
Carb – 44.57g
Fiber – 0.63g
Ash – 1.4g
Total:  82.32g x 1000 = 82,320mg
Phosphorus:  177.66mg / 82,320mg = 0.002158 x 100% = 0.2158%
Protein:  20.77 / 82.32  x 100 = 25.23%

This recipe may be very helpful for a kitty in advanced renal insufficiency, but for a cat that is still in the early stages of CRF/CRI, I fear this recipe may do more harm than good.  The phosphorus level is very attractive, but the low low protein content is definitely NOT.  The idea behind low-protein diets for CRF/CRI cats is to lessen or lower the amount of protein metabolic wastes in the blood (BUN and Creatinine).  But lowering the protein intake of a strict carnivore is a two-edged sword... the diet may help the kidneys... but acat is more than a pair of kidneys... they need protein to repair body tissues and organs and muscles... etc...  So, personally, (and this is just me), I would not feed such a restricted protein diet to a CRF cat unless we are looking at Stage IV CRF.

I like Dr. Pitcairn's renal recipe a little better than Strombeck's - it is a little higher in protein content and the phosphorus load is still very attractive.

Dr. Pitcairn's Feline Diet for Kidney Problems
1 1/3 cups (2/3 pound) ground chicken, turkey or lean heart
4 cups cooked white rice
4 eggs
2 tablespoons cold-pressed safflower, soy or corn oil
1,500 milligrams calcium (around 1.3:1)
1/8 teaspoon iodized salt
1/8 teaspoon potassium chloride (optional , for a saltier flavor)
1 teaspoon parsley, finely grated carrot or other vegetable (optional)
5,000 IU vitamin A
Taurine and other cat vitamins (about 5 days' worth)
50 milligram level B complex (or 10 milligrams per day)
2,500 milligrams vitamin C (½ teaspoon sodium ascorbate)
Mix everything together in a large bowl.  Serve raw if the cat will accept it.  Otherwise, mix all but the vitamins together, bake about 20 minutes in a moderate oven and then wait until it cools to mix in the vitamins.  Occasionally, substitute 1 to 3 teaspoons of liver for part of the meat.

Calories: 2167
Protein: 135g
Fat: 76.23g
Carb: 220.31g
Fiber: 2.53g
Ash:  7.41g
Total:  441.48  x 1000 = 441,480mg
Phosphorus: 1248.38  / 441,480  =  0.002827 x 100 = 0.2827%
Protein:   135 / 441.48  x 100  =  30.578%

Wonderful analysis, kaffe!  Thanks so much!

I too wondered about the Strombeck recipe back when my Tessa was diagnosed last year - 1/4 cup chicken to 1 cup rice??!!

A supplement question - will pumpkin work for the Vit A requirements?  I was reading the can the other night & it said 1/4 cup for a person was 70% daily reqmt for vit A.  Seems like that would give cats enough vit A without added supplements.

This is a recipe I made for darling Elvis - the KING of JustMe's household, who, BTW, is NOT exactly a kidney cat... he just commissioned Kaffe Kooks to run a recipe for his Majesticness - just in case (kings... tou know?)




Elvis the King's Renal Recipe

450g         Ground turkey
50g      Ground chicken liver
100g      Cooked and mashed or pureed mixed vegetables:
                        a.  50g  squash for GI health
                        b.  20g  kale – source of iron, good for kidney kitties who tend to anemia
                        c.  30g yam – great source of potassium – good for kidney kitties who tend to
                             hypokalemia
100g                    Uncooked white or brown rice
1 tsp      Ground eggshell powder (1.6 : 1)
1000mg      Taurine (important for heart function)
2000mg                Salmon Oil (important for good kidney function)
200IU      Vit. E (important antioxidant and should be used with any fish body oil)
2 tabs      B-50 Vitamin B-Complex (important bec kidney kitties pee a lot and B-
                         vitamins get washed out in the urine)
1/8 tsp                  Potassium Chloride (salt substitute) or iodized salt or Dulse
[edit:  there is some question as to the suitability of potassium chloride in a kidney cat's diet - may contribute to metabolic acidosis to which kidney cats are prone]
Calories:  1552.2
Protein: 143.18g
Fat: 62.81g
Carbs: 93.45g
Fiber: 4.37g
Ash: 7.19g
Total:  311g x 1000 = 311,000
Phosphorus:  1166. 8mg   /  311,000  x 100%  =  0.3751%
Protein:   143.18  /  311 x 100%  = 46.038%

Method:
1.  Cook ground turkey and liver in a little bit of water... do not brown
2.  Cook the vegetables in water and mash them together
3.  Over-boil the rice (around 30mins)
4.  Combine all ingredients and run them through blender with enough water for processing


I think these are great ratios... I only hope King Elvis will approve and eat the dang thing!

Thanks, Petslave... just thought a lot of us will be needing something like this.
About pumpkin... (canned)... the Vit A in pumpkin are alpha and beta carotenes... cats have a limited ability to metabolize these ... they need pre-ormed Vit A which can only be obtained from the flesh of their prey... that's why we need to include liver in their diet... I found though that in senior cats, they don't need as much vit A as would a kitten and youn adult and skipping liver from several meals for them may actually be beneficial.

I've PM'd you, Petslave.. check your box

This is a grainless renal recipe for Petslave's kitties, Tessa and Tony:




Tessa and Tony's Grainless Renal Recipe

450g      Ground lean top sirloin beef  OR ground chicken thighs
50 g      Beef liver OR chicken liver (if using chicken thigh)
100g                    Mashed potato (prepared from dehydrated flakes, w/o milk or butter
                         added)
100g      Green Peas (you can use frozen)
50g      Carrot, cooked, grated  OR kale
50g      Pumpkin, canned
1 tsp      Ground Eggshell (or 1800mg elemental calcium carbonate)
1/8 tsp              Potassium Chloride (salt substitute) or iodized salt or Dulse
[edit:  there is some question as to the suitability of potassium chloride in a kidney cat's diet - may contribute to metabolic acidosis to which kidney cats are prone]

1000mg                 Taurine
1000mg               Salmon Oil
200IU      Vit E
2 caps      B-50 Vit B Complex
2/3 - 1 C             Spring or distilled Water

Method:
1.  Cook all meats and veggies.
2.  Combine all ingredients and run through a blender or food processor with sufficient water for processing

Calories: 1710
Protein: 141.4g
Fat:  76.65
Carb: 107.8
Fiber:  15.45
Ash:  10.35
Total:  351.65g  x  1000  = 351,650mg
Phosphorus:  1230mg  /  351,650  x  100%  = 0.3497%
Protein:   141.4  /  351.56  x 100%  = 40.21%
Fat:  76.65  / 351.65  x 100%  = 21.797%
Carb:  107.8  / 351.65  x 100% = 30.655%
Fiber:  15.45  / 351.65  x 100% =  2.943%


** Since we are using mashed potatos (rich source of potassium), the recipe is a little high on carbs.  One can lower the carb load by lessening the amount of mashed potato and substituting the removed amount with equal amount of the other veggies.  For example, if youtake away 50 grams of mashed potato, put in 50 grams of peas or carrot or pumpkin or spread the50grams among all three.

Thank you, sweet Kaffe. On the Strombeck recipe, you can up the chicken breast to about a third of a cup,
about 6 ounces, and cut the rice down a little, just a smidge (1/4 to 1/2 cup), as Rachel Ray would say. Just for variety
and to reduce some of the low protein problems from batch to batch, week to week. Crf kitties are just as parsnickety
as all the other felines. Then you serve and cross your fingers. You may want to consider potassium gluconate powder,
rather than chloride, if there are blood pressure issues. There's also calcium carbonate powder instead of the tablet.
Home eggshells baked at 350 for 10 minutes and processed in a coffee grinder are the best. Of course don't forget to add your phosphorous blockers, Epakitin or aluminum hydroxide gel powder. Alternagel about 30 minutes before eating if you're using it. Consult your vet, and bloodwork
often, unfortunately. There are some B vitamins that are liquid that you might want to investigate. Organic rice. Fresh clams, too, lightly
processed in water to minimize Taurine destruction. Puree in a food processor, and add as much water as you can for your more
advanced kidney kitties. Also fun to watch your vet tear their hair out as you're discussing modifications based on bloodwork, but
if you have a good one, they will these days.

Yes- That will help, 3Cat!  adding a bit more chicken or reducing the rice a bit in the Strombeck recipe is very workable... thanks for giving us the tip.  I have heard of the extreme finickiness of CRI/CRF kitties when it comes to food... no wonder many have resorted to feeding FF and just add binders... in this case, I must agree with everyone that getting Fluffy to eat overrides everything else... the best and most healthy food is absolutely useless if Fluffy won't eat it!   Cheesy

I really really MUST work on some kind of kitty-flavor enhancer!  I should've taken a few more courses in chemistry!  ha ha ha ha

Been tinkering with that recipe for a while, Kaffe, that's all. All the recipes sound
great and better than most of the chemically loaded commercial ones. Had some
rough results with six months on a prescription diet at my house. But always consult
your vet and watch crf behavior for signs.
