There are some other important amino acids and vitamins (listed
below) that your cat cannot live without. Again, all are
components of animal tissues. Just like taurine, they are all
degraded or destroyed in the cooking process. In regular cooked
commercial cat foods they have to be added in a chemical form after
the cooking process.
1. Arginine is essential for the elimination of protein
wastes. Cats are extremely sensitive to even one meal without
Arginine and would die quickly if it was not contained in their diet.
2. Arachidonic Acid is needed for immune response, blood
clotting and reproductive function. Unlike a dog's liver, a cat's
liver lacks the enzyme needed to convert common linoleic acid to
3. Cysteine is needed in large quantities for the synthesis of
cats' own special amino acid called "felinine". Felinine is
required for proper kidney function. Because our food provides cysteine, cats with kidney problems typically react well to eating Wild Kitty Cat Food.
4. Unlike other mammals, cats cannot synthesize Vitamin A
naturally from carotenoids in a cat's system as it is in other
mammals. Therefore, cat have to eat preformed Vitamin A which is
found in high densities in livers and in egg yolks.
5. Likewise cats cannot synthesize Vitamin B12, yet it
is necessary in their diets. Vitamin B12 is present only in animal products.
6. Niacin is another essential nutrient that cats cannot
naturally synthesize in useful amounts, yet they need it. Meat is a
rich, natural source of niacin. Diets based on cereals will always be
deficient in niacin for cats.
