Editing Kitten (section)

====Amino acids====
The lack of readily available [[glucose]] from the limited carbohydrates in the diet has resulted to the adaptation of the liver to produce glucose from the breakdown components of protein—amino acids. The enzymes that breakdown amino acids are constantly active in cats. Thus, cats need a constant source of protein in their diet.<ref name="Sheridan" /> Kittens require an increased amount of protein to supply readily available amino acids for daily maintenance and for building new body components because they are constantly growing.<ref name="Sheridan" /> There are many required amino acids for kittens. [[Histidine]] is required at no greater than 30% in kitten diets, since consuming histidine-free diets causes weight loss.<ref name="Ander">{{cite journal|last1=Anderson|first1=P|last2=Baker|first2=D|last3=Sherry|first3=P|last4=Corbin|first4=J|title=Histidine, phenylalanine-tyrosine and tryptophan requirements for growth of the young kitten|journal=Journal of Animal Science|date=1980|volume=50|issue=3|pages=479–483|doi=10.2527/jas1980.503479x|pmid=7364684|s2cid=1583258}}</ref> [[Tryptophan]] is required at 0.15%, seeing as it maximizes performance at this level.<ref name="Ander"/> Kittens also need the following amino acids supplemented in their diet: [[arginine]] to avoid an excess of ammonia in the blood, otherwise known as [[hyperammonemia]], [[isoleucine]], [[leucine]], [[valine]], [[lysine]], [[methionine]] as a sulfur-containing amino acid, [[asparagine]] for maximal growth in the early post-weaning kitten, [[threonine]] and taurine to prevent central retinal degeneration.<ref name="Ander"/>
