Editing Kitten (section)

=== Post-weaning nutrition ===

==== Fat ====
Until approximately one year of age, the kitten is undergoing a growth phase where energy requirements are up to 2.5 times higher than maintenance. Pet nutritionists often suggest that a commercial cat food designed specifically for kittens should be offered beginning at four weeks of age. Fat has a higher caloric value than carbohydrates and protein, supplying 9 kcal/g. The growing kitten requires arachidonic and linoleic acid which can be provided in omega-3 fatty acids. Docosahexaenoic acid (DHA) is another vital nutrient that can be supplied through omega 3 fatty acid. Addition of DHA to the diet benefits the cognition, brain and visual development of kittens.

==== Protein ====
Cats are natural carnivores and require high amounts of protein in the diet. Kittens are undergoing growth and require high amounts of protein to provide essential amino acids that enable the growth of tissues and muscles. It is recommended that kittens consume a diet containing approximately 30% protein, on a dry matter basis, for proper growth.

Taurine is an essential amino acid found only in animal tissue; the mother cat cannot produce enough of it for her kittens. As it is an indispensable amino acid, it must be provided exogenously through the diet at 10 mg per kg of bodyweight, each day. Kittens deprived of taurine can experience poor growth and can result in retinal degeneration in cats.

==== Carbohydrates ====
Felines are natural carnivores and do not intentionally consume large quantities of carbohydrates. The domestic cat's liver has adapted to the lack of carbohydrates in the diet by using amino acids to produce glucose to fuel the brain and other tissues.   Studies have shown that carbohydrate digestion in young kittens is much less effective than that of a mature feline with a developed gastrointestinal tract. Highly digestible carbohydrates can be found in commercial kitten food as a source of additional energy as well as a source of fiber to stimulate the immature gut tissue. Soluble fibre such as beet pulp is a common ingredient used as a fibrous stool hardener and has been proven to strengthen intestinal muscles and to thicken the gut mucosal layer to prevent diarrhea.
