Growth assays were conducted to estimate the minimal dietary requirement levels of histidine, tryptophan, phenylalanine and tyrosine for the young kitten. Dietary concentrations of histidine and tryptophan of .30 and .15%, respectively, were found to support optimal kitten performance. A preliminary study of the total aromatic amino acid (TAAA) requirement indicated that no more than 1.20% TAAA (.60% phenylalanine + .60% tyrosine) is required by the kitten. Subsequent experiments revealed no…

The tryptophan requirement of the kitten
1. To estimate the tryptophan requirement of the kitten, six male and six female kittens were presented diets containing 0·7, 0·9, 1·1, 1·3, 1·5 and 3·0 g tryptophan/kg diet for six experimental
Histidine requirement of kittens for growth, haematopoiesis and prevention of cataracts
TLDR
The histidine requirement of growing kittens was determined from an experiment in which forty-eight kittens were randomly allocated to six amino acid-based diets supplying: 1.0 and 1.5 g histidine/kg diet, which showed a significant effect of dietary histidine on haemoglobin concentration.
Cats require more dietary phenylalanine or tyrosine for melanin deposition in hair than for maximal growth.
TLDR
Dietary concentrations >18 g total aromatic amino acids/kg diet promote a greater ratio of PTCA:total melanin in hair, unaware of a secondary nutrient requirement being so much greater than the requirement for growth.
Performance of piglets in response to the standardized ileal digestible phenylalanine and tyrosine supply in low-protein diets.
TLDR
In conclusion, it is recommended not to use a Phe+Tyr requirement in the ideal AA profile but rather use a SID Phe : Lys of 54% and a Sid Tyr: Lys of 40% to support maximal growth.
Do cats really need more protein
TLDR
The adult cat requires 12–15 per cent dietary protein for maintenance compared with about 4–5 per cent for the adult rat, man and dog.
Nutrition of the domestic cat, a mammalian carnivore.
TLDR
The cat appears to have less capability to adapt to most changes in dietary composition because it cannot change the quantities of enzymes involved in the metabolic pathways, which has resulted in more stringent nutritional requirements for cats than for omnivores such as the rat, dog, and man.
Assessment of the neurologic effects of dietary deficiencies of phenylalanine and tyrosine in cats.
TLDR
It is suggested that chronic dietary restriction of phenylalanine and tyrosine in cats may result in a predominantly sensory neuropathy, which appears to be greater for normal neurologic function than that required in short-term growth experiments.
