A Cat’s Nutritional Needs

1 A Cat’s Nutritional Needs

Protein

Protein is the material basis of life and the most basic and important component of body cells and tissues. Protein digested from food falls into two types: plant protein and meat protein. Humans can absorb both, but cats differ—they mainly absorb meat protein; plant protein is indigestible for them. So cats need lots of meat daily, whether fed commercial food or home-cooked meals—pay special attention. Most meats suit cats, e.g., chicken, beef, fish.

Vitamins

Vitamins are organic compounds in metabolism; two matter most for cats and are in high demand: vitamin E and the B complex. Vitamin E fights oxidative damage; deficiency causes anorexia and depression. The B complex breaks down and absorbs nutrients and regulates the nervous and endocrine systems; deficiency causes poor development, liver disease, and nerve disorders.

Egg yolk, carrot, and lean meat are rich in B-complex vitamins; nuts, dairy, and vegetable oils are rich in vitamin E. If a cat eats rat poison, timely vitamin K also reduces harm.

Trace elements

Trace elements are minerals needed in small amounts but essential. Calcium is vital for bone development, with demand dropping after adulthood; deficiency causes poor bone growth. Zinc handles protein and carbohydrate metabolism, aids wound healing, and keeps skin healthy; deficiency slows development and causes skin disease. Last, copper—important during pregnancy—takes part in connective tissue and blood formation, crucial for fetal development.
