Hi Petsalve!
A few months ago, I did tinkerwith the home-made version of Hill's K/D diet and came up with this:
This is a home-prepared version of a popular and vet-recommended prescription diet for CRF cats (think k/d protein-restricted diet):
454 grams 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
Method: Dice and braise the meat in the vegetable oil and retain the fat. Combine all ingredients and mix well. Add water as necessary to increase palatability. Keep extra food covered in refrigerator. In addition, you must give a multi-vitamin and mineral supplement to your cat plus 250mg of taurine each day.
I have a BIG problem with this recipe. The only “meat” is organ meat – liver. Think of all that Vit A! Ay! The only other protein source is egg. This surprises me because the humble egg yolk has one of the highest phosphorus values per 100 grams – higher than chicken or beef or turkey. And too much phosphorus is supposed to be a “no-no” for CRF kitties. All that grain too! The calcium-to-phosphorus ratio is also a little on the high side calcium-wise (according to NATS, this recipe has 1014 mg phosphorus and one teaspoon eggshell contains around 1800 mg calcium carbonate). On the plus side, it mentions using ground eggshell as the calcium source. Recent research has shown eggshells to be a viable oral phosphorus binder. Now, I don’t have a CRF kitty (Praise the Lord). But I can’t help tinkering with this recipe and make it more like something I would actually feed my own cats. I would start by reducing the liver and using an animal protein source like pork or chicken instead of eggs. I would also minimize or completely eliminate the rice and put mixed pureed veggies in its stead. How’s this:
100 grams Braised or raw organic chicken heart
100 grams Braised or raw organic chicken gizzard
200 grams Braised or raw organic chicken dark meat (thigh or drumstick)
50 grams Braised or raw organic chicken liver
100 grams Cooked and pureed mixed organic kitty veggies (any three of these:
carrots, zucchini, broccoli, peas, squash, pumpkin, asparagus)
100-200 grams Cooked organic grains like oats or barley flakes (no rice or wheat or corn
please and absolutely no rice bran as rice bran has been shown to "leech" taurine from cat's GI)
1 to 1-1/2 cups water for processing - make it a little "soupy"
2/3 tsp Ground/powdered egg shell (Cal: Phos = 1.3: 1)
1/8 tsp Potassium chloride salt substitute
1000mg Taurine
add supplements like vit B, vit C, vit E, salmon/fish oil/freshly ground flaxseed (for the omegas but NO cod liver oil!)
Phosphorus from meats: 908mg
vit A: 8544IU
Now, if you have a CRF kitty, PLEASE consult yor vet or vet nutritionist before you try any diet.
I know you said "no grains." If you absolutely cannot use any type of grains, then in yur shous, I would simply substitute with vegetables... peas is a good choice I think.
If you remove the gizzards from this recipe, you'll come up with an even lower phosphorus recipe. Its just that gizzards are quite tasty to some cats
I am presently tinkering with another CRF/CRI recipe that has to be low fat as well as low phosphorus (for a freind)... hard juggling act... I will post as soon as I perfect the ratios... oh, by the way... you can make the calcium-to-phosphorus ratio in a CRF recipe higher like 1.5 (cal):1 --- especially if you are using eggshell.
